Difference Between T-SQL and PL-SQL

SQL is a standard that has been adopted by ANSI in 1986. It has been used as a base by many RDBMS (relational database management system) vendors. Both T_SQL and PL-SQL are relational database management system and are an extension to the Structured Query Language.

The difference that separates T-SQL from PL-SQL is their proprietary. T-SQL is a Microsoft product whereas, the PL-SQL is a product of Oracle. In this article, I have tried to explain some more differences between T-SQL and PL-SQL with the help of a comparison chart.

Comparison Chart

Basis for Comparison	T-SQL	PL-SQL
Product	T-SQL is a product of Microsoft.	PL-SQL is a product of Oracle.
Full Form	Transact-Structured Query Language	Procedural Language-Structured Query Language.
Feature	Offers a great degree of control on how an application works.	Integrates well with the SQL.
Server	T-SQL performs best with Microsoft SQL server.	PL-SQL server performs best with Oracle database server.

Definition of T-SQL (Transact – SQL)

Transact-SQL is a product Microsoft, and it is an extension to SQL. T-SQL is entirely a database programming language which has variables, functions, data definition, data manipulation statements, loops conditional statements and procedures.

T-SQL also features function for string operation, mathematical operations, date and time processing, error checking. This kind of add-ons makes T-SQL turing complete, which means this computing language is universally accepted.

T-SQL performs best when used with Microsoft SQL servers as it is a Microsoft proprietary.

Definition of PL-SQL (Procedural Language – SQL)

PL-SQL is a Procedural extension to Structured Query Language Which was developed by Oracle Corporation in early 90’s for its own database management. As PL-SQL is an extension to SQL, that means the SQL statements are embedded in procedural language statements.

PL-SQL is a block structured language; it executes the block of code at a time. PL-SQL being procedural extension allows declaring variables, constants, functions, loops, procedures, packages, etc. Like procedural language, it also features error handling. These features make PL-SQL turing complete which means like T-SQL, PL-SQL is also universally accepted.

With the help of PL-SQL, you can create applications, server pages that would display the information, obtained by the SQL statements in the code of PL-SQL.

Conclusion

Both are the Relational Database Management Systems and use SQL as their standard language. Neither of them can be preferred over the other. It is up to the user which language to choose.
