Daniel Barclay (Drill) commented on DRILL-2689:
-----------------------------------------------

A SQL <separator> is not usually required between a <nondelimiter token> (e.g., "]") and a <delimiter token> (e.g., the "LIMIT" keyword).

Is there some overriding rule that requires a space in the reported case?
