SQL-92

SQL-92 was the third revision of the SQL database query language.

Unlike SQL-89, it was a major revision of the standard.

The standard specification itself grew about five times compared to SQL-89.

Many of the new features had already been implemented by vendors before the new standard was adopted.

[1] However, most of the new features were added to the "intermediate" and "full" tiers of the specification, meaning that conformance with SQL-92 entry level was scarcely any more demanding than conformance with SQL-89.
