SQL: Delete Vs Truncate Vs Drop
 
08:27
In this tutorial, you'll learn the difference between delete/drop and truncate. PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

UPDATE STATEMENT WITH JOIN IN ORACLE SQL
 
07:18
This video demonstrates how user can update data of a particular table(t1), based on the join condition with other table(t2). So it would be a easy way to ditch the for-loop, and check for the condition every time. What was to be achieved from the for-loop can be achieved with a single simple update statement. A simple trick to update data in table based on some conditional data in some another table, would help you to increase the performance of your code massively. For ex : UPDATE TABLE1 t1 SET COL1 = (SELECT COL FROM TABLE2 t2 where t1.col = t2.col);

In this video, I show you how to filter for a SQL null or empty string. It can be difficult to filter a null because you can't simply compare with an equal sign. You have to use a special IS NULL clause to make the filter work. I also show you how to combine both the SQL Null and Empty String together in a special trick with the isnull SQL Server function.

This means we no longer have to use multiple statements for performing Insert, Update and Delete. With merge statement we require 2 tables 1. Source Table - Contains the changes that needs to be applied to the target table 2. Target Table - The table that require changes (Inserts, Updates and Deletes) The merge statement joins the target table to the source table by using a common column in both the tables. Based on how the rows match up as a result of the join, we can then perform insert, update, and delete on the target table. Merge statement syntax MERGE [TARGET] AS T USING [SOURCE] AS S ON [JOIN_CONDITIONS] WHEN MATCHED THEN [UPDATE STATEMENT] WHEN NOT MATCHED BY TARGET THEN [INSERT STATEMENT] WHEN NOT MATCHED BY SOURCE THEN [DELETE STATEMENT] Example 1 : In the example below, INSERT, UPDATE and DELETE are all performed in one statement 1. When matching rows are found, StudentTarget table is UPDATED (i.e WHEN MATCHED) 2. When the rows are present in StudentSource table but not in StudentTarget table those rows are INSERTED into StudentTarget table (i.e WHEN NOT MATCHED BY TARGET) 3. When the rows are present in StudentTarget table but not in StudentSource table those rows are DELETED from StudentTarget table (i.e WHEN NOT MATCHED BY SOURCE) Create table StudentSource ( ID int primary key, Name nvarchar(20) ) GO Insert into StudentSource values (1, 'Mike') Insert into StudentSource values (2, 'Sara') GO Create table StudentTarget ( ID int primary key, Name nvarchar(20) ) GO Insert into StudentTarget values (1, 'Mike M') Insert into StudentTarget values (3, 'John') GO MERGE INTO StudentTarget AS T USING StudentSource AS S ON T.ID = S.ID WHEN MATCHED THEN UPDATE SET T.NAME = S.NAME WHEN NOT MATCHED BY TARGET THEN INSERT (ID, NAME) VALUES(S.ID, S.NAME) WHEN NOT MATCHED BY SOURCE THEN DELETE; Please Note : Merge statement should end with a semicolon, otherwise you would get an error stating - A MERGE statement must be terminated by a semi-colon (;) In real time we mostly perform INSERTS and UPDATES. The rows that are present in target table but not in source table are usually not deleted from the target table. Example 2 : In the example below, only INSERT and UPDATE is performed. We are not deleting the rows that are present in the target table but not in the source table. Truncate table StudentSource Truncate table StudentTarget GO Insert into StudentSource values (1, 'Mike') Insert into StudentSource values (2, 'Sara') GO Insert into StudentTarget values (1, 'Mike M') Insert into StudentTarget values (3, 'John') GO MERGE INTO StudentTarget AS T USING StudentSource AS S ON T.ID = S.ID WHEN MATCHED THEN UPDATE SET T.NAME = S.NAME WHEN NOT MATCHED BY TARGET THEN INSERT (ID, NAME) VALUES(S.ID, S.NAME);

Part 12   Can we join two tables without primary foreign key relation
 
10:38
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/09/part-12-can-we-join-two-tables-without.html Can we join two tables without primary foreign key relation Yes, we can join two tables without primary foreign key relation as long as the column values involved in the join can be converted to one type. ID column in Departments table is not the primary Key and DepartmentId column in Employees table is not the foreign key. But we can still join these tables using ID column from Departments table and DepartmentId column from Employees table, as both the columns involved in the join have same data type i.e int. Select Employees.Name as EmployeeName, Departments.Name as DepartmentName from Employees join Departments on Departments.ID = Employees.DepartmentId The obious next question is, if primary foreign key relation is not mandatory for 2 tables to be joined then what is the use of these keys? Primary key enforces uniqueness of values over one or more columns. Since ID is not a primary key in Departments table, 2 or more departments may end up having same ID value, which makes it impossible to distinguish between them based on the ID column value. Foreign key enforces referential integrity. Without foreign key constraint on DepartmentId column in Employees table, it is possible to insert a row into Employees table with a value for DepartmentId column that does not exist in Departments table. The following insert statement, successfully inserts a new Employee into Employees table whose DepartmentId is 100. But we don't have a department with ID = 100 in Departments table. This means this employee row is an orphan row, and the referential integrity is lost as result Insert into Employees values (8, 'Mary', 'Female', 80000, 100) If we have had a foreign key constraint on DepartmentId column in Employees table, the following insert statement would have failed with the following error. Msg 547, Level 16, State 0, Line 1 The INSERT statement conflicted with the FOREIGN KEY constraint. The conflict occurred in database "Sample", table "dbo.Departments", column 'ID'.

Self join in sql server - Part 14
 
11:19
In this video we will learn about 1. Self Join - Joining a table with itself 2. Self Join is not a different type of join. It can be classified as Inner Self Join, Outer Self Join (Left, Right and Full), or Cross Self Join.

Subqueries in sql   Part 59
 
14:34
In this video we will discuss about subqueries in sql server. Let us understand subqueris with an example. Please create the required tables and insert sample data using the script below. Create Table tblProducts ( [Id] int identity primary key, [Name] nvarchar(50), [Description] nvarchar(250) ) Create Table tblProductSales ( Id int primary key identity, ProductId int foreign key references tblProducts(Id), UnitPrice int, QuantitySold int ) Insert into tblProducts values ('TV', '52 inch black color LCD TV') Insert into tblProducts values ('Laptop', 'Very thin black color acer laptop') Insert into tblProducts values ('Desktop', 'HP high performance desktop') Insert into tblProductSales values(3, 450, 5) Insert into tblProductSales values(2, 250, 7) Insert into tblProductSales values(3, 450, 4) Insert into tblProductSales values(3, 450, 9) Write a query to retrieve products that are not at all sold? This can be very easily achieved using subquery as shown below. Select [Id], [Name], [Description] from tblProducts where Id not in (Select Distinct ProductId from tblProductSales) Most of the times subqueries can be very easily replaced with joins. The above query is rewritten using joins and produces the same results. Select tblProducts.[Id], [Name], [Description] from tblProducts left join tblProductSales on tblProducts.Id = tblProductSales.ProductId where tblProductSales.ProductId IS NULL In this example, we have seen how to use a subquery in the where clause. Let us now discuss about using a sub query in the SELECT clause. Write a query to retrieve the NAME and TOTALQUANTITY sold, using a subquery. Select [Name], (Select SUM(QuantitySold) from tblProductSales where ProductId = tblProducts.Id) as TotalQuantity from tblProducts order by Name Query with an equivalent join that produces the same result. Select [Name], SUM(QuantitySold) as TotalQuantity from tblProducts left join tblProductSales on tblProducts.Id = tblProductSales.ProductId group by [Name] order by Name From these examples, it should be very clear that, a subquery is simply a select statement, that returns a single value and can be nested inside a SELECT, UPDATE, INSERT, or DELETE statement. It is also possible to nest a subquery inside another subquery. According to MSDN, subqueries can be nested upto 32 levels. Subqueries are always encolsed in paranthesis and are also called as inner queries, and the query containing the subquery is called as outer query. The columns from a table that is present only inside a subquery, cannot be used in the SELECT list of the outer query. Next Video: What to choose for performance? Queries that involve a subquery or a join Text version of the video http://csharp-video-tutorials.blogspot.com/2013/01/subqueries-in-sql-part-59.html Slides http://csharp-video-tutorials.blogspot.com/2013/09/part-59-subqueries-in-sql-server.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
