):T-SQL,

• or Transact-SQL, is a database programming language developed by Microsoft. It is an extension of standard Structured Query Language (SQL) and includes additional features that make it easier to interact with relational databases, such as SQL Server. T-SQL is used to create queries, stored procedures, triggers, and other operations on the database.

and FROM clauses:

• In SQL language, the SELECT clause is used to retrieve data from one or more tables in a database. It allows you to specify the desired fields and can include aggregation functions to perform calculations on the data. The FROM clause is used to indicate from which table or set of tables the data should be retrieved.

Simple Query:

• A simple query refers to a basic statement of fetching data from a database. It usually involves using the SELECT clause to specify the desired fields and the FROM clause to indicate the source of the data. Simple queries are fundamental for data analysis and manipulation, allowing the extraction of specific information from the database according to the user's needs.
