The 本製品 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.
