product: | |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 | |
Problem description: | |
"group by 1" syntax which MSSQL does not support is pushed down to MSSQL incorrectly: SELECT MIN(ID1) FROM (SELECT ID1 FROM NICK1 UNION ALL SELECT ID2 FROM NICK2) 1 ----------- SQL1822N Unexpected error code "42000" received from data source "MSSQL2008". Associated text and tokens are "Each GROUP BY expression must contain at least one col". SQLSTATE=560BD To recreate the issue: SET PASSTHRU MSSQL2008; DROP TABLE TABLE1; DROP TABLE TABLE2; CREATE TABLE [TABLE1]( [ID1] [int]); CREATE TABLE [TABLE2]( [ID2] [int]); SET PASSTHRU RESET; CREATE NICKNAME NICK1 FOR "MSSQL2008"."dbo"."TABLE1"; CREATE NICKNAME NICK2 FOR "MSSQL2008"."dbo"."TABLE2"; SELECT MIN(ID1) FROM (SELECT ID1 FROM NICK1 UNION ALL SELECT ID2 FROM NICK2); From explain, we can see following query is pushed down to MSSQL: RMTQTXT : (Remote statement) SELECT MIN( A0."ID1") FROM "dbo"."TABLE1" A0 GROUP BY 1 | |
