SQL is the standard language to query a database.
PL SQL basically stands for “Procedural Language extensions to SQL.” This is the extension of Structured Query Language (SQL) that is used in Oracle.
T-SQL basically stands for ” Transact-SQL.” This is the extension of Structured Query Language (SQL) that is used in Microsoft.
In this tutorial, we will learn-
Difference between SQL and PL/SQL
- SQL is a single query that is used to perform DML and DDL operations.
- PL/SQL is a block of codes that used to write the entire program blocks/ procedure/ function, etc.
- It is declarative, that defines what need to be done, rather than how things need to be done.
- PL/SQL is procedural that defines how the things needs to be done.
- Execute as a single statement.
- Execute as a whole block.
- Mainly used to manipulate data.
- Mainly used to create an application.
- Interaction with a Database server.
- No interaction with the database server.
- Cannot contain PL/SQL code in it.
- It is an extension of SQL, so that it can contain SQL inside it.
Difference Between T-SQL and PL-SQL
- T-SQL is a Microsoft product.
- PL-SQL is developed by Oracle.
- Full Form of TL SQL is Transact Structure Query language.
- Full Form of PL SQL is Procedural Language Structural Query Language.
- T-SQL gives a high degree of control to programmers.
- It is a natural programming language that blends easily with the SQL
- T-SQL performs best with Microsoft SQL server
- PL-SQL performs best with Oracle database server.
- It is easy and simple to understand.
- PL-SQL is complex to understand.
- T-SQL allows inserting multiples rows into a table using the BULK INSERT statement.
- PL/SQL supports oops concepts like data encapsulation, function overloading, and information hiding.
- SELECT INTO statement used in T-SQL
- INSERT INTO statement must be used in PL/SQL
- In T-SQL NOT EXISTS clause used along with SELECT statements.
- In PL/SQL, there is a MINUS operator, which could be used with SELECT statements
Difference between SQL and T-SQL
- SQL is a programming language which focuses on managing relational databases.
- T-SQL is a procedural extension used by SQL Server.
- This is used for controlling and manipulating data where large amounts of information are stored about products, clients, etc.
- T-SQL has some features that are not available in SQL. Like procedural programming elements and a local variable to provide more flexible control of how the application flows.
- SQL queries submitted individually to the database server.
- T-SQL writes a program in such a way that all commands are submitted to the server in a single go
- The syntax was formalized for many commands; some of these are SELECT, INSERT, UPDATE, DELETE, CREATE, and DROP.
- It also includes special functions like the converted date () and some other functions which are not part of the regular SQL.
