Problem summary
**************************************************************** * USERS AFFECTED: All DB2 10 and 11 for z/OS users of a SQL * * statement containing UNION ALL and one of * * the sub-query select list of UNION ALL * * references a column with BLOB data type. * **************************************************************** * PROBLEM DESCRIPTION: An ABEND04E RC00C900D0 at location * * DSNXGRDS DSNXROHB OFFSETCD80 may occur * * when a statement satisfies all of the * * following list of conditions: * * * * 1. A fullselect statement contains * * UNION ALL. * * * * 2. One of the sub-query select list of * * UNION ALL references a column with * * BLOB data type. * * * * 3. The corresponding of other sub-query * * select list of UNION ALL is BINARY * * or VARBINARY data type. * **************************************************************** * RECOMMENDATION: * **************************************************************** The following example helps to illustrate the problem. Step 1. Create TABLE T1 and T2. CREATE TABLE T1( C1 INTEGER, C2 BINARY(2) ); CREATE TABLE T2( C1 FLOAT, C2 BLOB(4) ); Step 2. Populate Table T1 and T2. INSERT INTO T1 VALUES (1, BINARY('BB', 2)); INSERT INTO T1 VALUES (2, BINARY('CB', 2)); INSERT INTO T2 VALUES (3, BLOB('CCBB')); INSERT INTO T2 VALUES (4, BLOB('CCBB')); Step 3. statement which can cause ABEND04E. SELECT C1, C2 FROM T1 UNION ALL SELECT C1, C2 FROM T2; DB2 does not process the data type conversion of BINARY column T1.C2 properly which can result in the ABEND.
Problem conclusion
DB2 has been modified correctly to process data type conversion to avoid the ABEND. Additional keywords: SQLUNIONALL SQLLOB
