Case TS010900705 shows that Optim PROP does not support self-referencing referential integrity relationships.
The enhancement request is apparently to support it.
Workaround available: In general Optim masking using Lookup should work here. You need to list all keys that can occur and the masking of them to a new value, in a Lookup table. Then Optim does not use PROP but uses Lookup to mask the columns that are involved.
Bonjour,
Pour information, le ticket ouvert sur ce sujet est le TS010900705.
Vous pourrez y lire tout l'historique sur ce sujet, notamment la prise en compte d'une colonne Oracle (et non DB2) en VARCHAR pour l'utilisation de la fonction Nextval. La colonne en question ne contient que des caractères numériques et la fonction Nextval Oracle fonctionne correctement dans ce cas.
Au bout de quelques mois, ce ticket a fait l'objet d'un correctif IBM que nous avons installé et qui fonctionne correctement sauf dans le cas des relations réflexives. C'est ce cas bien précis qui nous gêne encore et nous oblige à utiliser des moyens détournés et pas très agréables pour couvrir tous les cas de peuplement qui nous sont demandés.
Cordialement, Frédéric Mosbach
Note, a SEQUENCE in Db2 can only be a numeric datatype (smallint, bigint, int, decimal)
Question 2: Is there an IBM Case number for this as a problem?
Optim PROP NEXTVAL is usually used for a SEQUENCE column. What does the client expect to be the behavior when there is a character column value?
