Problem summary
**************************************************************** * USERS AFFECTED: All DB2 9 for z/OS and DB2 10 for z/OS * * users who use BINARY and VARBINARY data * * types. * **************************************************************** * PROBLEM DESCRIPTION: Incorrect output may occur for an SQL * * statement that contains a predicate * * comparing a BINARY value with a * * VARBINARY value. * **************************************************************** * RECOMMENDATION: * **************************************************************** Incorrect output may occur for an SQL statement that contains a predicate comparing a BINARY value with a VARBINARY value. For example, CREATE TABLE MYTAB1 (COL1 BINARY(5)) ; CREATE TABLE MYTAB2 (COL1 VARBINARY(5)) ; INSERT INTO MYTAB1 VALUES (BINARY('ABC')); INSERT INTO MYTAB2 VALUES (VARBINARY('ABC')); SELECT HEX(MYTAB1.COL1) FROM MYTAB1, MYTAB2 WHERE MYTAB2.COL1 = MYTAB1.COL1; Two binary strings are equal only if the lengths of the two strings are identical. If the strings are equal up to the length of the shorter string, the shorter string is considered less than the longer string even when the remaining bytes in the longer string are hexadecimal zeros. In the SELECT statement above, one record 'C1C2C30000' is returned when no record is expected(RNF). This problem happens because DB2 doesn't handle the data types correctly when comparing the two values.
Problem conclusion
DB2 code is fixed to handle the data types correctly when comparing BINARY with VARBINARY values. Additional Keywords: SQLINCORR SQLINCORROUT INCORROUT DB2INCORR/K
