      Description

      The following SQL doesn't work:

      EXPLAIN 
      SELECT alias.a, alias.b, alias.c, COUNT(DISTINCT d) 
      FROM table_name alias 
      GROUP BY alias.a, alias.b, alias.c 
      GROUPING SETS( (alias.a), (alias.b, alias.a) ); 
      FAILED: ParseException line 15:34 missing ) at ',' near '<EOF>' 
      line 16:0 extraneous input ')' expecting EOF near '<EOF>' 
      

      The following SQL works (without alias in grouping set):

      EXPLAIN 
      SELECT a, b, c, COUNT(DISTINCT d) 
      FROM table_name 
      GROUP BY a, b, c 
      GROUPING SETS( (a), (b, a) ); 
      

      Alias works for just one column:

      EXPLAIN 
      SELECT alias.a, alias.b, alias.c, COUNT(DISTINCT d) 
      FROM table_name alias 
      GROUP BY alias.a, alias.b, alias.c 
      GROUPING SETS( (alias.a) ); 
      

      Using alias in GROUPING SETS could be very useful if multiple tables are involved in the SELECT (via JOIN)
