Wikipedia

Transact-SQL (T-SQL) is Microsoft's and Sybase's proprietary extension to the SQL (Structured Query Language) used to interact with relational databases. T-SQL expands on the SQL standard to include procedural programming, local variables, various support functions for string processing, date processing, mathematics, etc. and changes to the DELETE and UPDATE statements.

Example from Wikipedia:
-- begin transaction BEGIN TRAN BEGIN TRY -- execute each statement INSERT INTO MYTABLE(NAME) VALUES ('ABC') INSERT INTO MYTABLE(NAME) VALUES ('123') -- commit the transaction COMMIT TRAN END TRY BEGIN CATCH -- roll back the transaction because of error ROLLBACK TRAN END CATCH
