Oracle SQL Tutorial 25 - ASCII and Unicode
 
03:33
In the previous video we talked about some of the most popular data types. We are going to discuss them in more detail. The data type we are going to start with is CHAR and NCHAR. I told you of both of these but I never explained the difference. That's because there is some other stuff I need to explain before I can explain the difference. This has to deal with what is known as character sets. When you have a string, there are only so many characters you are allowed to store in that string. The characters you are allowed to store is determined by what is known as the character set. A common character set is ASCII. This character set allows you to store English characters, numbers, and some symbols. ASCII started with 127 characters, and then they came out with the ASCII extended, which allows for up to 255 characters. Even with 255 characters though, we are limited in what we can store using one character set. If the computer only allows ASCII, we are going to be limited when working with different languages. Of course it works for some situations, but globalization of software has been a big thing with the development of the interwebs …and the movement towards a new world order (Revelation 13:7). That means that ASCII is no longer the best character set. It has largely been replaced with a character set known as Unicode. Oracle has a few Unicode character sets that we can use when we work with string data. When you start studying character sets, I can promise that you will run across the word encoding. Encoding refers to the way that the allowed characters can be stored on the computer. A computer doesn't just store a letter, everything has to be stored in binary. Unicode is the character set, but it has numerous different encodings. Essentially, the computer can store the same characters in multiple different ways, depending on which encoding is used. The most popular encodings for Unicode are UTF-8 and UTF-16. UTF stands for Unicode Transformation Format. In the next video we will be discussing these in detail and express their differences. Once we got that down, we'll be able to loop back around to data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

ASCII Function in SQL Query with Example
 
01:33
ASCII(): ASCII function returns the NUMBER code that represents the specified character. Sytax: ASCII( single_character ) PARAMETERS: single_character is the specified character to retrieve the NUMBER code for. If more than one character is entered, the ASCII function will return the value for the first character and ignore all of the characters after the first. Let's look at some Oracle ASCII function examples and explore how you would use the ASCII function in Oracle/PLSQL. For example: ASCII('C') would return 67 ASCII('T') would return 84 ASCII('T2') would also return 84 Thanks for watching...:)

Oracle SQL Tutorial 26 - UTF-8 and UTF-16
 
05:46
UTF-8 and UTF-16 are different encodings for the Unicode character set. Let's discuss UTF-8 first. UTF-8 is what is known as a variable-length character set. This means that the amount of storage a character takes up depends on what character it is. For example, if we store the character A, it will only take up one byte. In fact, ASCII is a subset of UTF-8. That means UTF-8 encoding can work with ASCII data. If you are new to computer storage, a byte is a very small amount of information. The smallest thing a computer can store is a bit. 1 or 0. On or off. There are 8 bits in a byte, 1024 bytes in a kilobyte, 1024 kilobytes in a megabyte, 1024 megabytes in a gigabyte, and 1024 gigabytes in a terabyte, and 1024 terabytes in a petabyte. Considering it is completely possible for a database to be multiple petabytes, you can understand that a byte is very small. If you store a non-English character, the size of UTF-8 will increase to 2, 3, or 4 bytes. If you think back to when we used the VARCHAR data type, we passed in 50 CHAR. The reason we throw in that CHAR is that the default for Oracle is 50 characters. Now you can understand why adding the CHAR might be important. If a character can take up multiple bytes, you cannot guarantee 50 characters. Now, on to UTF-16. UTF-16 is also a variable length encoding, but it differs in that It is either 2 or 4 bytes. That means to store an A, it now takes two bytes rather than one. Even though a byte is so small, when you are storing billions of characters, an unnecessary byte really adds up to a lot of wasted storage. We can only represent so many characters with 2 bytes. When we run out of options, we move to four bytes to allow for other characters. Which do we use? It often depends on what platform you are on and also what languages you are working with. For example, if you are working with Asian language, UTF-16 stores each character in 2 bytes while UTF-8 stores each character in 3 bytes. So you could save space by using UTF-16. Additionally, UTF-16 works better when you are writing code in Java or something from Microsoft .NET because UTF-16, or a subset of it called UCS-2, is widely adopted. Other than that, UTF-8 will be the one you want. Now that we have built a pretty good foundation of character sets, we can now continue our discussion of data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 32 - VARCHAR2 and NVARCHAR2
 
03:06
This video we are going to discuss the VARCHAR2 and the NVARCHAR2 data types. The previous videos are a good foundation to this video. I've actually discussed so much stuff in those videos that I don’t have a whole lot to say. Good for you, right? I discussed over the previous videos that you should prefer to use VARCHAR2 over CHAR. That's because there is not a difference in performance or storage for a VARCHAR2 column. The only difference is that an CHAR column forces each value to take up a certain length even if it's not. There is one difference between the variable length and fixed length data types here that you need to know about, and that is storage limits. CHAR has a limit of 2000 bytes, while VARCHAR2 has a limit of 4000 bytes. That means you can store twice as much junk in a VARCHAR2 column! Other than that, these data types work exactly the same. I recommend you always use the VARCHAR2 data types instead of the CHAR data types, and only use NVARCHAR2 if you have a non-Unicode database. This will allow you to store Unicode characters in a column. Now, the amount of storage you can put in a VARCHAR2 column is twice what you can put in a CHAR column, but 4000 characters is still not very many characters. This is where the LOB data types come in, which we will discuss in the next video! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 27 - CHAR Part 1
 
03:52
This video and the next is going to cover CHAR and NCHAR. Be sure to check out the previous two videos as these are going to introduce you to some foundational knowledge required to understand these data types. CHAR is a fixed-length data type. What that means is that every value for a CHAR column is going to be the same length. You specify the length in parenthesis when you create the table. The thing you need to know though is that the default measurement is in bytes. That means if you specify the length to be CHAR(50), the length of each value will be 50 bytes, by default. If you want to change that to 50 characters, you can pass in the word CHAR as in CHAR(50 CHAR). This is known as a qualifier. Specifically, they are known as length semantics qualifiers (describes the meaning of the given length). Now, I said the default was bytes, but you can actually change the default to characters. In that situation, you can actually use the keyword BYTE to break away from the default. In general, it's best to put CHAR or BYTE even if it is the default. In general, it's best to keep things consistent. It's okay to have these measured in CHAR or BYTE, but it is recommended that every column is the same. It allows you to be more consistent as if some columns measure length in bytes and some measure length in characters, things can get confusing. If you do want to change the default, look up NLS_LENGTH_SEMANTICS as well as the potential problems it may bring. What values are allowed in parenthesis? That is what we are going to discuss in the next video. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle LTRIM Function
 
03:06
https://www.databasestar.com/oracle-trim/ The Oracle LTRIM function allows you to remove a specific character from the left side of a string. It’s one of the most commonly used string manipulation functions in SQL, in my experience. The “L” in “LTRIM” stands for “left”. It’s often used to remove spaces from the left of a string. However it can be used to remove other characters, such as leading characters from URLs. The syntax for the LTRIM function is: LTRIM(input_string, [trim_character]) The input_string is the text you want to remove characters from. It can be any kind of expression, such as a specific text value or a column. The trim_character is the character you want to remove from the left of the string. It’s an optional parameter, and if you don’t specify it, then a space character is used by the function. The parameters can be any type of string. The function will return either a VARCHAR2 or a LOB data type, depending on the type of data you specify in the parameters. You can specify more than one value for the trim_character, and the LTRIM function will remove both characters from the left of the string. The function is similar to the RTRIM value, where RTRIM removes characters from the right of the string. For more information on the LTRIM function, including the SQL used in this video, read the related article here: https://www.databasestar.com/oracle-trim/

Oracle SQL Tutorial 28 - CHAR Part 2
 
03:33
Now this video is a continuation of the last video. I decided to break the video up into sections so they didn't cover so much information and drag on for 10 minutes. This video we are going to talk about the length of CHAR. Now it is important to remember that CHAR is a fixed-length data type. This means that every row's value for this column is going to have the same length. The length is given to the database by specifying the length in parenthesis, such as CHAR(10). If you give a value shorter than that, it will be padded with spaces. What range is allowed though? The lowest is actually one. The highest is 2000. Now, remember that Oracle allows either the specification of CHAR or BYTE. The limit of 2000 is actually 2000 bytes. What happens if you put 2000 CHAR? Well, Oracle actually lets you do that. What is the problem with this though? The problem is that not all characters are 1 byte. This means that our 2000 CHAR is inaccurate. This will only work with 1 byte characters. This might not seem like a big problem, but it can lead to runtime errors in code that uses our database. A runtime error is when our code runs and in certain circumstances we get an error and others we do not. If we allow a user to insert up to 2000 characters, but they decide to use multibyte characters such as Chinese, we will get an error. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 29 - NCHAR Part 1
 
04:58
NCHAR is another data type available in Oracle database. This data type is very similar to the char data type with some key differences. NCHAR is also known as the national character set. This is a data type that allows us to store Unicode characters. It is really recommended that you watch the two videos over Unicode and UTF-8 because this video is going to talk a lot about it. Why is it that we have an entire data type dedicated to storing Unicode? That will be easily understood once we understand how character sets and encodings are applied to Oracle. They are applied at the database level. That means that you have a character set that applies to the entire database. This is in contrast to some database management systems that allow you to apply a data type at the table and column level. For example, in MySQL you can make a table have a character set, and make a specific column in that table a different character set. That means we can customize everything at the expense of adding potential complexity and confusion. Oracle does not work that way. In Oracle, we define one character set for the entire database. The problem with defining a character set for the entire database is that it may not be the character set we want to use for everything. That is where the NCHAR column comes in. The NCHAR column allows us to have a Unicode column inside of a database that does not use Unicode as the default character set. That is important because it is very often that we want to use Unicode but we may not need to use it for everything, for example if that application is working with ASCII nearly all of the time. If you are using Unicode for the database, then NCHAR is not going to be needed and should not be used. This data type is not as widely accepted, so only use it if you absolutely need to, specifically when you need to store Unicode in a non-Unicode database. Additionally, there is some controversy when it comes to whether or not you should use the CHAR and NCHAR data types in Oracle at all. We will discuss why in an upcoming video. In the next video we are going to go over some specific character sets that Oracle can use.

Oracle DECOMPOSE Function
 
01:41
The Oracle DECOMPOSE function is used to transform a string into a Unicode string. It will split a character that has an accent, for example, into two characters. It’s the opposite of the COMPOSE function. The syntax of the DECOMPOSE function is: DECOMPOSE ( input_string [CANONICAL|COMPATIBILITY] ) The parameters of this function are: - input_string is the string that will be decomposed into separate character values in a string. It can be any character data type. - CANONICAL|COMPATIBILITY is an optional parameter and allows you to specify the mode of decomposition. CANONICAL is the default. CANONICAL means it can be re-composed with the COMPOSE function. COMPATIBILITY means that it can’t be re-composed, but it can be useful for katakana characters.

Oracle SQL Tutorial 30 - UTF-8 and UTF-16 Character Sets
 
04:01
A few videos ago we discussed UTF-8 and UTF-16 encoding, but when we are working with a database we do not worry about encodings as much as we do character sets. That's because a specific character set is going to have a specific encoding. The reason I am making this video is to introduce you to the most common character sets and to teach you the differences. That’s because as we go into the national character sets we need to understand the information taught in this video. So the first character set I am going to teach you about is AL32UTF8. AL32UTF8 is a character set that uses the uff-8 encoding and each character can take up to 4 bytes with the utf-8 encoding. There is another character set (not encoding) called utf8 (no hyphen) which is also encoded with UTF-8. This can be a little confusing because UTF8 is the name of an encoding and a character set, but bear with me. Both of these character sets are UTF-8 encoded, but UTF8 uses an older version of UTF-8 encoding. Generally, they work about the same, but the way certain characters are stored is slightly different, specifically way certain characters are stored is slightly different, specifically what are known as supplementary characters, which take up 4 bytes. The max size for a UTF8 character set is 3 bytes, as they do not directly support the supplementary characters as 4 bytes but instead store them across 2 groups of 3 bytes each. Oracle recommends that you use AL32UTF8 for all future development instead of the archaic UTF8 character set. There is another character set that you should know about, and that is AL16UTF16, which uses the UTF-16 encoding. Watch my video over UTF-8 and UTF-16 to learn more about UTF-16. Lastly, there is a character set known as UTFE, which uses an encoding known as UTF-EBCDIC. This is like a super archaic character set, and I'm not even going to talk about it. I thought I would at least mention it as it is going to come up a bit in the next video's topic. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 15 - How to Add Primary Key Constraints
 
02:54
The goal of this video is to take the CREATE TABLE statement we have and walk through the different ways to create primary keys. This and foreign keys are the most common constraints, so we need to make sure that you have this one down. Once we have a more complex database design with multiple tables, we will learn the proper way to create foreign keys. For now, I am going to keep all of our constraints at the column level, unnamed. The only exception is the primary key, because that is what we are focusing on in this video. The first way to create the primary key is at the column level, unnamed. The primary key is very important because it what we use to distinguish rows from one another. Every table you create is going to need a primary key, and I suggest putting a lot of effort into making sure your keys are set up correctly and organized. --Delete the table if needed: DROP TABLE users; CREATE TABLE users( user_id NUMBER PRIMARY KEY, username VARCHAR2(50 CHAR) NOT NULL UNIQUE ) The next way is at the column level, but named: --Delete the table: DROP TABLE users; CREATE TABLE users( user_id NUMBER CONSTRAINT users_pk PRIMARY KEY, username VARCHAR2(50 CHAR)NOT NULL UNIQUE ) The general naming convention here is the table name followed by an underscore, followed by pk for primary key. Finally, the third way, which is at the table level, is the way we are going to create our primary key: --Delete the table: DROP TABLE users; CREATE TABLE users( user_id NUMBER, username VARCHAR2(50 CHAR) NOT NULL UNIQUE, CONSTRAINT users_pk PRIMARY KEY (user_id) ) Now, once you've created these constraints, you can use Oracle SQL Developer to find these constraints. Open your databases in the connections tab and find the table in the Tables folder. Double click your table and travel to the Constraints tab. You can tell here that the UNIQUE constraint still exists in this table, but it has a pretty disgusting name. It kind of wants to make me puke. Referencing that constraint in the future with that wacky name would be a burden. Engrave these three options in your head so that you can use any of them whenever you need and can read other peoples' code. Thank you for sticking with the series thus far. In the next video, we will be…doing something. See you then! :) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me on Patreon! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oralce CHR Function
 
01:38
https://www.databasestar.com/oracle-chr/ The Oracle CHR function allows users to provide a numeric code and return the ASCII character that matches the code. It’s the opposite of the ASCII function, which allows you to provide a character and return the code for that character. The syntax of the CHR function is: CHR(number_code [, USING NCHAR_CS]) The number code parameter is the code that you want to return the equivalent character for. The USING NCHAR_CS keyword means that the national character set will be used. More information on character sets can be found here: One common use of the CHR function is CHR(10). The number 10 is the line feed character, or “new line”, and is often used to start a new line of text. CHR(13) is also a common use, which is a carriage return. CHR(9) is a tab character. For more information on the Oracle CHR function, including the SQL used in this video, read the related article here: https://www.databasestar.com/oracle-chr/

Oracle SQL Tutorial 24 - Important Data Types
 
06:09
In the upcoming videos we are going to discuss data types in depth, but I don't want to drown you in all of the details. Because of that, I'm giving you this video which is going to introduce you to the most important data types. Then, in the upcoming videos, I'll describe them in more depth. One of the data types we've already discussed in this video is NUMBER. This data type is used to, obviously, store a number. It can be used to store integers (whole numbers), or numbers with decimals. There are two other numeric data types you should know of. BINARY_FLOAT and BINARY_DOUBLE are both numeric data types that are known as floating point numbers. A floating point number is often used for large numbers that have decimal places where it is acceptable to not be completely precise. What I mean by this is that these numbers can only store numbers correctly up to a certain decimal point. If you need perfect precision, you will want to use the NUMBER data type. Now storing numbers is good sometimes, but occasionally you will want to store string data. String data can be any sequence of characters, including numbers. By telling the database that a column is a string data type, the database knows how to treat that column. There are four important string data types that you need to know about. The first two are CHAR and NCHAR. These data types are used to store a fixed-length string. So for example, you can say you want to store 12 characters. This means that every value for this column will be exactly 12 characters. If you insert less than 12 characters, the data will be padded with spaces. This means you will want to use one of these data types when every value in the column is the same length. What is the difference between CHAR and NCHAR? CHAR uses what is known as ASCII while NCHAR uses Unicode. The difference is what characters are allowed and how much space each character takes. ASCII takes up less space but only supports English, numbers, and some symbols. UNICODE allows you to store characters from multiple languages but takes up more space. Those were both fixed-length string. What if you want to store data that changes in length? That is where VARCHAR2 and NVARCHAR2 come in. When it comes to storing dates, the data types that are most important are DATE and TIMESTAMP. Date can be used to store dates and time. Timestamp is a data type that can be used to store an exact moment in time. Lastly, there are interval types. These store a date range. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

CHR Function in SQL Query with Example
 
01:36
CHR(): The Oracle/PLSQL CHR function is the opposite of the ascii function. It returns the character based on the NUMBER code. Syntax: CHR( number_code ) Here number_code is the NUMBER code used to retrieve the character. Example: Let's look at some Oracle CHR function examples and explore how you would use the CHR function in Oracle/PLSQL. CHR(116) would return 't' CHR(84) would return 'T' Thanks for watching...:)

What is CONTROL CHARACTER? What does CONTROL CHARACTER mean? CONTROL CHARACTER meaning

What is CONTROL CHARACTER? What does CONTROL CHARACTER mean? CONTROL CHARACTER meaning - CONTROL CHARACTER definition - CONTROL CHARACTER explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In computing and telecommunication, a control character or non-printing character is a code point (a number) in a character set, that does not represent a written symbol. They are used as in-band signaling to cause effects other than the addition of a symbol to the text. All other characters are mainly printing, printable, or graphic characters, except perhaps for the "space" character (see ASCII printable characters). All entries in the ASCII table below code 32 (technically the C0 control code set) are of this kind, including CR and LF used to separate lines of text. The code 127 (DEL) is also a control character. Extended ASCII sets defined by ISO 8859 added the codes 128 through 159 as control characters, this was primarily done so that if the high bit was stripped it would not change a printing character to a C0 control code, but there have been some assignments here, in particular NEL. This second set is called the C1 set. These 65 control codes were carried over to Unicode. Unicode added more characters that could be considered controls, but it makes a distinction between these "Formatting characters" (such as the Zero-width non-joiner), and the 65 Control characters. The Extended Binary Coded Decimal Interchange Code (EBCDIC) character set contains 65 control codes, including all of the ASCII control codes as well as additional codes which are mostly used to control IBM peripherals.
