JOIN Queries
The add-in supports the complete join syntax in Presto. Presto supports inner joins, outer joins, and cross joins. The default is inner. Multiple join operations are supported.
SELECT field_1 [..., field_n] FROM table_1 [[AS] alias_1] [[INNER|[FULL|RIGHT|LEFT] OUTER|CROSS] JOIN [EACH] table_2 [[AS] alias_2] [ON join_condition_1 [... AND join_condition_n]] ]+
Note that the default join is an inner join. The following limitations exist on joins in Presto:
- Cross joins must not contain an ON clause.
