Procedures in SQL

A pre-compiled stored procedure is a logical unit made up of one/more SQL statements (SQL stands for Structured Query Language). The database server saves it as an object. An SQL procedure is a collection of SQL statements and logic that is written and saved to accomplish a specified goal. An SQL procedure consists of a name, a parameter list, and a set of Transact-SQL statements. Stored procedures are stored as named objects in SQL Database Server.
