History of Standards
The first standard for SQL was published in 1986 and commonly known as SQL-1. An amendment to this standard, containing support for referential integrity, was published in 1989. The next major version of the standard was published in 1992 and is often referred to as SQL-92 (or SQL-2.) In 1996 a standard for stored procedures and functions was published (SQL/PSM), which was followed by the next major version, SQL-99. As mentioned, the current standard was published in 2016 and is called SQL-2016.
