View & manage your progress/pace 3. In-class projects and code reviews 4. Personal guidance from your Mentors ---------------------------------------------------------------------------------------- A variable is nothing but a name given to a storage area that our programs can manipulate. Each variable in PL/SQL has a specific data type, which determines the size and layout of the variable's memory; the range of values that can be stored within that memory and the set of operations that can be applied to the variable. The name of a PL/SQL variable consists of a letter optionally followed by more letters, numerals, dollar signs, underscores, and number signs and should not exceed 30 characters. By default, variable names are not case-sensitive. You cannot use a reserved PL/SQL keyword as a variable name. PL/SQL programming language allows to define various types of variables, which we will cover in subsequent chapters like date time data types, records, collections, etc. For this chapter, let us study only basic variable types. With PL/SQL you can declare variables and then use them in SQL and procedural statements anywhere that an expression can be used. Variables can be used for the following: • Temporary storage of data: Data can be temporarily stored in one or more variables for use when validating data input and for processing later in the data flow process. • Manipulation of stored values: Variables can be used for calculations and other data manipulations without accessing the database. • Reusability: After they are declared, variables can be used repeatedly in an application simply by referencing them in other statements, including other declarative statements. • Ease of maintenance: When using %TYPE and %ROWTYPE (more information on %ROWTYPE is covered in a subsequent lesson), you declare variables, basing the declarations on the definitions of database columns. If an underlying definition changes, the variable declaration changes accordingly at run time. This provides data independence, reduces maintenance costs, and allows programs to adapt as the database changes to meet new business needs. More information on %TYPE is covered later in this lesson. Types of Variables" All PL/SQL variables have a data type, which specifies a storage format, constraints, and valid range of values. PL/SQL supports four data type categories—scalar, composite, reference, and LOB (large object)—that you can use for declaring variables, constants, and pointers. • Scalar data types hold a single value. The main data types are those that correspond to column types in Oracle server tables; PL/SQL also supports Boolean variables. • Composite data types, such as records, allow groups of fields to be defined and manipulated in PL/SQL blocks. • Reference data types hold values, called pointers, that designate other program items. Reference data types are not covered in this course. • LOB data types hold values, called locators, that specify the location of large objects (such as graphic images) that are stored out of line. LOB data types are discussed in detail later in this course.

Oracle SQL Tutorial 12 - Intro to Constraints
As I believe I've mentioned in an earlier video, a constraint is basically a rule we can put in our database that prevents someone from putting the wrong data in. It protects our relationships and data integrity. Because the goal of these constraints are to protect our data integrity, you may hear them called integrity constraints. There are many integrity constraints we are going to talk about: NOT NULL UNIQUE PRIMARY KEY FOREIGN KRY CHECK There is also the DEFAULT attribute. These are all keywords we can add to our columns that will change the way the database works with our data and also prevents incorrect data. NOT NULL is a constraint you can put on a column that prevents nulls. A null is the absence of a value. When we say null, we are saying that every single row has to have a value for this column. UNIQUE is a constraint that makes every row have a unique value for this column. Now note, this does not require values to be put it, and it will allow multiple rows to be null. Next, we are going to talk about primary keys. What qualifies a column as a candidate key? First, not a single row should have a null for that column. Second, every row must be unique. The primary key constraint is essentially a combination of the NOT NULL constraint and the UNIQUE constraint. The foreign key constraint sets the requirement that any value in this column for any row must match a row in another column. Check constraints allow us to be more strict with what data is allowed in our database. NOT NULL and UNIQUE give some level of restriction, but what if we want something more specific? For example, what if we only want values between 0 and 100? That is where check constraints come in. When using check constraints, you give a boolean expression. A boolean expression is something that can be evaluated to true or false. It will only insert the row if the value you try to put into the row makes the expression evaluate to true. So if you put in a value too great or small, the expression will be false and the data is not allowed to be entered. The default constraint is a value you can give a column, and if for any reason when the row is created in the table a value is not provided, the default value will be given. So for example, we could have a bank account table where the balance defaults to 0. How do you actually implement these constraints when you are creating a table? In the next video we are going to be adding these to our users table.

Oracle SQL Tutorial 23 - Intro to Data Types
Every column within a table has to be given what is known as a datatype. A data type is a fairly simple concept when you dissect the word. It is literally the type of data. Why do we use types, though? The biggest benefit is so that Oracle knows how to interpret and work with our data. It also makes the database better at rejecting incorrect data. If we had to concept of a data type, there would be a lot more work involved in forcing data to be of the right format. It would also be harder for us to get the database to treat the data in the correct way. In addition to this, a database can optimize storage and performance for a column if everything is of the same data type. Because of this, each column can only support one data type. There are numerous different data types in Oracle and it helps us if we categorize them. The first types of datatypes we should learn about are: String, Numeric, Temporal Now, there are few more categories we could make, but these are the main ones. We will worry about the other ones another day as I am only introducing the topic. A string data type is anything within quotes. Most databases use single quotes for string data. Inside of the quotes can be any number of characters. What is a character? Think of any letter, number, or symbol you can type. Some people call these letters, numbers, and symbols alphanumeric. Numeric data type includes only numbers. These data types are often used for data that you plan on using for mathematical calculations. Temporal data types are data types that are used for dates and times. Now, each data type is probably going to have some options you'll need to worry about, but one that comes up with every data type is storage. The reason we need to consider storage is because we may end up with millions of rows in a table and the difference between a few bytes for each row will make a huge difference when we look at the whole picture. When a data type gives you the option of size, you will want to a size that will be able to hold what you need, but nothing more. In the upcoming videos we are going to discuss the available data types in more detail. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

IIF function in SQL Server
iif function in sql server 2012 iif function in sql server example sql server iif function example In this video we will discuss IIF function in SQL Server. IIF function Introduced in SQL Server 2012 Returns one of two the values, depending on whether the Boolean expression evaluates to true or false IIF is a shorthand way for writing a CASE expression Syntax : IIF ( boolean_expression, true_value, false_value ) Example : Returns Male as the boolean expression evaluates to TRUE DECLARE @Gender INT SET @Gender = 1 SELECT IIF( @Gender = 1, 'Male', 'Femlae') AS Gender Example : Using IIF() function with table data. We will use the following Employees table for this example. SQL Script to create Employees table Create table Employees ( Id int primary key identity, Name nvarchar(10), GenderId int ) Go Insert into Employees values ('Mark', 1) Insert into Employees values ('John', 1) Insert into Employees values ('Amy', 2) Insert into Employees values ('Ben', 1) Insert into Employees values ('Sara', 2) Insert into Employees values ('David', 1) Go Write a query to display Gender along with employee Name and GenderId. We can achieve this either by using CASE or IIF. Using CASE statement SELECT Name, GenderId, CASE WHEN GenderId = 1 THEN 'Male' ELSE 'Female' END AS Gender FROM Employees Using IIF function SELECT Name, GenderId, IIF(GenderId = 1, 'Male', 'Female') AS Gender FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/iif-function-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/iif-function-in-sql-server_14.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists
