Problem IC95326 | Status: Geschlossen |
IN A FEDERATION SYSTEM, AN UPDATE/DELETE STATEMENT DOES NOT APPLY THE PREDICATES CONTAINING FUNCTION TEMPLATES | |

Problembeschreibung: | |
This problem is specific to the Federation feature of DB2 and when a remote function is mapped to the Federated server in DB2 as a function template. Any UPDATE/DELETE statement containing predicates with the function template does not apply such predicates. As a result, the UPDATE/DELETE statement might update or delete more rows than it should. For example, in a Federated system has a nickname N1(c1) is mapped to a remote table T1(c1) and a function template MY_LTRIM() is mapped to a function SYSIBM.LTRIM() at a remote server. Assume that the table T1(C1) has 2 rows of values 'A' and 'B'. The statement UPDATE N1 SET C1 = 'X' WHERE MY_LTRIM(C1) = 'A' should update only the first row from 'A' to 'X'. Without applying this fix, the statement will update all the rows to 'X'. Likewise, the statement DELETE N1 WHERE MY_LTRIM(C1) = 'A' should delete only the first row. It deletes all the rows without applying this fix. | |

Local-Fix: | |
Replace any usage of function templates in any predicates of UPDATE/DELETE statements with equivalent versions of local function in the Federated server. This could impact the performance of the UPDATE/DELETE. | |
