Hello. You need either SELECT ID, ARRAY_AGG(DISTINCT Item) Item FROM tbl2 GROUP BY ID or SELECT ID, GROUP_CONCAT(DISTINCT Item SEPARATOR ', ') Item FROM tbl2 GROUP BY ID depending on data type of expected result. Use ARRAG_AGG for ARRAY result or GROUP_CONCAT for VARCHAR result.
ARRAY_AGG is not available before H2 1.4.197, so use a recent version of H2. -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
