All Implemented Interfaces:

Context, Wrapper

class SqlGroupIdFunction
extends SqlAbstractGroupFunction

The GROUP_ID() function.

Accepts no arguments. If the query has GROUP BY x, y, z then GROUP_ID() is the same as GROUPING(x, y, z).

This function is not defined in the SQL standard; our implementation is consistent with Oracle.

Some examples are in agg.iq.
