T-SQL

T-SQL, or Transact-SQL, is an extension of SQL (Structured Query Language) used primarily in Microsoft SQL Server and Sybase databases. It allows users to manage and manipulate data by writing queries that retrieve, insert, update, and delete information from databases. T-SQL also includes programming features like conditional statements and loops, enabling complex data operations and automation. It plays a crucial role in data analysis, reporting, and application development, making it an essential tool for database administrators and developers in various industries.
