Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problembeschreibung: | |
DB2 may abend when the SQL statement satisfies all the following conditions: 1. Query has an equality predicate between simple column and a constant value, i.e. Q1.col1 = <literal>. 2. The same query block also has an OR predicate, e.g. "P1 OR P2 OR .. OR Pn", Pi stands for an OR subterm predicate. 3. An OR subterm predicate Pi contains "Pa1 AND Pa2.. AND Pak". One Pa is a provable FALSE predicate and another Pa is an EXISTS, NOT EXISTS, IN, or NOT IN predicate. | |
