[teiid-issues] [JBoss JIRA] (TEIID-5223) Problem with union aliasing when bind variables used

Problem with union aliasing when bind variables used ---------------------------------------------------- Key: TEIID-5223 URL: https://issues.jboss.org/browse/TEIID-5223 Project: Teiid Issue Type: Bug Affects Versions: 9.3.5 Reporter: Mike Higgins Assignee: Steven Hawkins Fix For: 10.2 When a query with a union, function call, and bind variables is issued in 9.3.5, an alias is not applied correctly. When the same query is run with an explicit constraint list, it works. It works in both cases in Teiid 9.3.4. Query is: SELECT Substances."SUB_ID", NADALM_FUNCS.MOLFILE(Substances."XCTAB") "MOLFILE" FROM ( SELECT NADALM.SUBSTANCE."SUB_ID", NADALM.SUBSTANCE."CTAB" "XCTAB", NADALM_FUNCS.MOLFILE(NADALM.SUBSTANCE."CTAB") "MOLFILE" FROM nadalm.substance UNION ALL SELECT D360_DC.DESIGN_COMPOUND."DC_ID" "SUB_ID", D360_DC.DESIGN_COMPOUND."CTAB" "XCTAB", NADALM_FUNCS.MOLFILE(D360_DC.DESIGN_COMPOUND."CTAB") "MOLFILE" FROM d360_dc.design_compound) Substances WHERE (Substances."SUB_ID" in (?, ?, ?, ?, ?, ?, ?,?, ?, ?)) Generated SQL with error is: SELECT v_0.SUB_ID, NADAL_CERTARA.MOLFILE(v_0.c_1) FROM (SELECT g_1."SUB_ID" AS c_0, g_1."CTAB" AS c_1 FROM "NADAL_CERTARA"."SUBSTANCE" g_1 WHERE g_1."SUB_ID" IN (?, ?, ?, ?, ?, ?, ?,?, ?, ?) UNION ALL SELECT g_0."DC_ID" AS c_0, g_0."CTAB" AS c_1 FROM "NADAL_CERTARA"."DESIGN_COMPOUND" g_0 WHERE g_0."DC_ID" IN (?, ?, ?, ?, ?, ?, ?, ?, ?, ?))) v_0 Note that top branch references v_0.Sub_id, which is not legal (should be c_0).
