?What is the difference between t-sql and pl/sql

T-SQL, also known as Transact SQL is a set of programming extensions from Sybase and Microsoft that add several features to the SQL, whereas PL SQL is a procedural language to create SQL

T SQL is term from Microsoft for Programming SQL Language, PL SQL is term from Oracle for Programming Language.

t-sql is a part of microsoft where as pl/sql is of oracle 

T-SQL (tha stands for Transact SQL) is the SQL language used for Microsoft SQL Server, while PL-SQL is the Oracle version of the SQL Language.

PL-sql is a procedural language used by oracle and T-sql is a proprietary language used by microsoft in sql server.

Both of them are for relational database the only difference between PL/SQL and T-SQL is that PL/SQL is product of ORACLE where as T-SQL is of Microsoft product

Although both systems use a version of Structured Query Language, or SQL, MS SQL Server uses Transact SQL, or T-SQL, which is an extension of SQL originally developed by Sybase and used by Microsoft. ... PL/SQL in Oracle can also group procedures together into packages, which can't be done in MS SQL Server.
