Ingo Bürk updated FLINK-22770:
------------------------------
Description:
The SET/RESET statements are currently implemented using regular expressions in
the ExtendedParser. They should instead be properly added to the grammar and
parser.
In a second step, the ExtendedParser implementation for it can be removed.
However, this would be a breaking change as key/value would then have to be
quoted (as they are in other places, i.e. table options) and no longer be
treated as SQL identifiers

The SET/RESET statements (DCL¹) are currently implemented using regular
expressions in the ExtendedParser. They should instead be properly added to the
grammar and parser.
In a second step, the ExtendedParser implementation for it can be removed.
However, this would be a breaking change as key/value would then have to be
quoted (as they are in other places, i.e. table options) and no longer be
treated as SQL identifiers.
¹ SET also exists in a no-argument version where it becomes DQL. For the scope
of this issue I'm excluding this here.
