We employ Structured Query Language (SQL), a declarative querying language approved by the American National Standards Institute, to interface with any RDBMS (ANSI). Transact-SQL is a Microsoft SQL extension that extends ANSI SQL features (T-SQL). T-SQL is a SQL standard that adds features and capabilities to make Microsoft SQL Server data access and manipulation more efficient, robust, and secure. A query in T-SQL tells SQL Server what you want, but it doesn't tell it how to achieve it. When SQL Server gets a query, it runs a series of processes to deal with it.
