INCORRECT VALUES MIGHT BE INSERTED INTO A TABLE WHEN AN INCORRECT PLAN IS CHOSEN FOR INSERT FROM SELECT | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 | |
Problembeschreibung: | |
Incorrect values might be inserted into a table as a result of an incorrect plan being chosen for an INSERT from a SELECT. The problem only occurs when intrapartition parallelism is enabled via the INTRA_PARALLEL database manager configuration parameter. The problem is more likely to occur if all of the following statements are true: - The table contains very wide columns -- close to 8KB or larger. - The reference to the target table in the subselect is within a separate query block. In the following example, t1 is the target table. Note how it is accessed in a separate query block in the subselect: insert into t1 select t2.* from t2, (select c00 from (select c00, ROWNUMBER() OVER() RN FROM t1 where c00 is not null) as t WHERE RN BETWEEN 30 AND 33) as TT where t2.c00 <> TT.c00. | |
