DB2 - Problem description
| Problem IC73847 | Status: Closed |
SQL1224N or SQL421N returned for inline SQL function with scalar aggregate function as parameter | |
| product: | |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 | |
| Problem description: | |
When the SELECT list of a result table of a SET operator (e.g.
UNION ALL, INTERSECT, etc.) references an inline SQL function
with a scalar aggregate function as input argument, DB2 may
return SQL0421N or terminate abnormally (SQL1224N).
When SQL1224N is returned, the trap file will contain the
following stack:
Signal #11
sqlnq_sem
sqlnp_smactn
sqlnp_parser
sqlnp_main
sqlnn_cmpl
sqlnn_cmpl
sqlra_compile_var
sqlra_find_var
sqlra_get_var
sqlri_ddl_get_section
sqlri_ddl_common
....
....
Examples:
CREATE FUNCTION lws.GETDOCID(docid VARCHAR(254)) RETURNS
VARCHAR(319)
LANGUAGE SQL
NO EXTERNAL ACTION
DETERMINISTIC
RETURN CONCAT(CONCAT('{DOCID$',docid), '}') ;
-- Example 1: SQL0421N
SELECT 'foo' as key
FROM sysibm.sysdummy1
UNION ALL
SELECT lws.GETDOCID(CHAR(ROW_NUMBER() OVER())) AS key
FROM sysibm.sysdummy1;
-- Example 2: SQL1224N
SELECT lws.GETDOCID(CHAR(ROW_NUMBER() OVER())) AS key
FROM sysibm.sysdummy1
UNION ALL
SELECT 'foo' as key
FROM sysibm.sysdummy1 ; | |
