Because this example specifies a sparse map, colocation_name defaults to db1_tableop1, which overrides the colocation name specified, if any, when the table operator was created.

SELECT * FROM db1.tableop1
    ( ON ( SELECT * FROM tab1) PARTITION BY col1
      ON ( SELECT * FROM tab2) PARTITION BY col2
      EXECUTE MAP = OneAMPMap
      USING myvalue(10,20)
    ) AS d1;
