Description
SQL is a domain-specific language used in programming and designed for managing data held in a relational database management system, or for stream processing in a relational data stream management system.
T-SQL (Transact-SQL) is a set of programming extensions from Sybase and Microsoft that add several features to the Structured Query Language (SQL), including transaction control, exception and error handling, row processing and declared variables.
All applications that communicate with SQL Server do so by sending T-SQL statements to the server. T-SQL queries include the SELECT statement, selecting columns, labelling output columns, restricting rows and modifying a search condition.
