SQL – Structured Query Language is a standard language for querying a database. PL SQL is called as Procedural language extension to SQL. T-SQL stands for Transact SQL. This is the extension of structured query language. T-SQL was originally developed by Sybase and now it is taken by Microsoft. T-SQL adds some advanced features to SQL to make it more powerful like declared variables, transaction variables and exception handling. These additions make T-SQL more complete which specifies the universality of a computing language.
PL SQL is an extension created by Oracle to have the benefits of looping, functions, variables. PL SQL block has three sections.
- Declare
- Begin
- Exception
Declare section:
Declare section is an optional section where we can declare the variables.
Begin section:
Begin is the section where all the SQL commands are written.
Exception section:
Exception block: if some error encounters in the earlier statements it is managed or handled in this block. Finally the project is finished by End statement.
For example
Procedures:
It is a named block of statement. It may or may not return the value.
Syntax:
Create PROCEDURE procedure name [parameter name [IN|OUT|INOUT]type[…,])]{IS|AS}
BEGIN
<procedure body>
End Procedure_name;
T-SQL uses some transactions which ensure data consistency.
Data types: In these sections there is lot of classification like numerics, Date and time, Character strings and Unicode character strings and binary strings.
- Numerics data types like BigInt and Int,smallInt ,decimal,Bit.
- Date and Time has Date ,Time,datetime2 etc.
- Character strings has Char, varchar.
- Unicode character strings has Nchar,Nvarchar
- Binary strings has Binary, Varbinary and image.
T-SQL Transactions:
Is a set of T-sql statements which executes together as a unit like we have
- COMMIT statement to save the changes.
- ROLL BACK statement to undo the changes before saving.
- SAVEPOINT statement splits the complete transaction in smaller parts for ROLL BACK.
- @@ TRANCOUNT counts the number of transactions for sql.
Difference between PL SQL and T-SQL
| PL SQL | T-SQL |
| PL SQL was developed by Oracle. | T-sql was developed by Microsoft. |
| It is a natural programming which is compatible with the sql and also provides better functionality. | it provides highest degree of control to the programmers |
| PL sql is good with its performance with oracle database server | T-sql is good with the performance with Microsoft sql server. |
| It is complex to understand and Use | it is much simpler and easy to Use |
| There is a AUTOCOMMIT Command which saves transactions automatically. | There is no AUTOCOMMIT command all transactions are saved manually. |
| here INSERT INTO statement must be used. | here SELECT INTO statement must be used. |
| PL sql provides OOPs concepts like data-encapsulation, function overriding etc | This allows inserting multiple rows into table using BULK INSERT statement. |
