## 34.45. `sql_languages`

The table `sql_languages` contains one row for each SQL language binding that is supported by Postgres Pro. Postgres Pro supports direct SQL and embedded SQL in C; that is all you will learn from this table.

This table was removed from the SQL standard in SQL:2008, so there are no entries referring to standards later than SQL:2003.
