Getting Started with PL/SQL Table Functions: Pipelined Table Functions
 
14:49
Pipelined table functions are table functions in which rows are returned or "piped" back to the calling query before the function has completed, avoiding the blocking behavior of normal PL/SQL functions and reduce PGA consumption. This video is part of the Oracle Dev Gym class "Getting Started with Table Functions". You can watch it independent of the class, but then you miss out on the tutorials and quizzes!

Turning Relational Database Tables into Spark Datasources
 
55:43
https://developer.oracle.com/code/online | Kuassi Mensah: This session presents a Spark data source for joining big data with master data in an RDBMS. It describes how such an implementation: Allows parallel and direct access to the RDBMS database (with the option of controlling the number of concurrent connections). Introspects the RDBMS table, generates partitions of Spark JDBCRDDs based on the split pattern, and rewrites Spark SQL queries into the RDBMS SQL dialect. Uses hooks in the JDBC driver for faster type conversions. Pushes down predicates to the RDBMS, prunes partitions based on the where clause, and projects columns to the RDBMS to reduce the amount of data returned and processed on Spark. Writes back the result set to the RDBMS table for use by traditional BI tools

SQL Server 2008 Partitioned Table and Parallelism
 
05:45
Detailed Article for "Partitioned Table and Parallelism" is available at : http://sqlserver-training.com/sql-server-2008-partitioned-table-parallelism-concept-video Follow us at more Updates at ----------------------------------------- Website : http://sqlserver-training.com/ Twitter : http://twitter.com/dbatag/ Facebook : http://facebook.com/dbatag/ Linked In : http://in.linkedin.com/in/dbatag/ ================================ SQL Server 2008 has removed the bottleneck of single-thread per partition over partitioned tables, which was found in SQL Server 2005. The previous bottleneck can cause performance problems under certain circumstances: On systems with many CPUs, if the table schema has less partitions than there are CPUs, then not all the CPUs will be used to process the query. Some examples: On a 32-way box, a query over a 12-partition table (e.g. a sales table partitioned by month) will only use 12 threads (one on each of 12 CPUs). This means 20 CPUs are potentially idle. On a 4-way box, a query over a 12-partition table only accesses a single partition so will only use one thread (on one CPU). This means 3 CPUs are potentially idle. On tables that have skewed data such that one partition is much larger than another, the length of time the query takes to complete will be bounded by the single thread processing the largest partition. As part of the set of improvements in SQL Server 2008 for data warehousing there will be an option to change the threading behavior for queries over partitioned tables. The new, alternative model is that all available threads process part of each partition and then move into the next partition. This allows all available CPUs to take part in processing the query, which should lead to a drop in the query completion time. The Following video shows, SQL Server 2008 -- Partitioned Table & Parallelism feature and shows graphically, how SQL Server 2008 has improved performance of Partitioned Tables.

Oracle DB Vs MySQL for Enterprise DataBase Deployments
 
08:54
Oracle DB is big, and expensive, but it brings a lot to the "table" when compared with MySQL. MySQL has limited ability to audit. MySQL's security is unsophisticated. There are no groups or roles, no ability to deny a privilege (you can only grant privileges). A user who logs in with the same username and password from different network addresses may be treated as a completely separate user. There is no built-in encryption comparable to Oracle. MySQL's Authentication is built-in. There is no LDAP, Active Directory, or other external authentication capability. MySQL has no MPP (massively parallel processing ) support. Unlike Oracle MySQL has no fractional-second storage type for times, dates, or intervals. There is no RAC (Real Application Cluster) support in My SQL, and no failover or server promotion either. These are strong features in Oracle MySQL's number of joins per query is limited to 61. Oracle's limit is much larger. MySQL Replication is asynchronous and has many limitations and edge cases. For example, it is single-threaded, so a powerful slave can find it hard to replicate fast enough to keep up with a less powerful master.

This means a given student can be enrolled into many courses and a given course can have many students enrolled. Below is the question asked in an interview for SQL Server Developer role. Write a SQL script to insert data into StudentCourses table. Here are the rules that your script should follow. 1. There will be 2 inputs for the script Student Name - The name of the student who wants to enroll into a course Course Name - The name of the course the student wants to enroll into 2. If the student is already in the Students table, then use that existing Student Id. If the student is not already in the Students table, then a row for that student must be inserted into the Students table, and use that new student id. 3. Along the same lines, if the course is already in the Courses table, then use that existing Course Id. If the course is not already in the Courses table, then a row for that course must be inserted into the Courses table, and use that new course id. 4. There should be no duplicate student course enrollments, i.e a given student must not be enrolled in the same course twice. For example, Tom must not be enrolled in C# course twice. Answer : To avoid duplicate student course enrollments create a composite primary key on StudentId and CourseId columns in StudentCourses table. With this composite primary key in place, if someone tries to enroll the same student in the same course again we get violation of primary key constraint error. Alter table StudentCourses Add Constraint PK_StudentCourses Primary Key Clustered (CourseId, StudentId) Here is the SQL script that inserts data into the 3 tables as expected Declare @StudentName nvarchar(50) = 'Sam' Declare @CourseName nvarchar(50) = 'SQL Server' Declare @StudentId int Declare @CourseId int -- If the student already exists, use the existing student ID Select @StudentId = Id from Students where StudentName = @StudentName -- If the course already exists, use the existing course ID Select @CourseId = Id from Courses where CourseName = @CourseName -- If the student does not exist in the Students table If (@StudentId is null) Begin -- Insert the student Insert into Students values(@StudentName) -- Get the Id of the student Select @StudentId = SCOPE_IDENTITY() End -- If the course does not exist in the Courses table If (@CourseId is null) Begin -- Insert the course Insert into Courses values(@CourseName) -- Get the Id of the course Select @CourseId = SCOPE_IDENTITY() End -- Insert StudentId & CourseId in StudentCourses table Insert into StudentCourses values(@StudentId, @CourseId) If required, we can very easily convert this into a stored procedure as shown below. Create procedure spInsertIntoStudentCourses @StudentName nvarchar(50), @CourseName nvarchar(50) as Begin Declare @StudentId int Declare @CourseId int Select @StudentId = Id from Students where StudentName = @StudentName Select @CourseId = Id from Courses where CourseName = @CourseName If (@StudentId is null) Begin Insert into Students values(@StudentName) Select @StudentId = SCOPE_IDENTITY() End If (@CourseId is null) Begin Insert into Courses values(@CourseName) Select @CourseId = SCOPE_IDENTITY() End Insert into StudentCourses values(@StudentId, @CourseId) End Use the following statement to execute the stored procedure Execute spInsertIntoStudentCourses 'Tom','C#'
