disable foreign key rules

Disable the Uniface implementation of the CAS and NULL foreign key rules on delete of a row in a one table.

USYS$ORA_PARAMS = disable foreign key rules

USYS$ORA_PARAMS = df

Description

When this option is set, Oracle handles the referential integrity rules.

By default, the Uniface CAS and NUL foreign key rules are enabled when using Oracle. When using Uniface, it is recommended that you do not change this default in a development environment otherwise there is an overhead of the data conversion procedure.

If you decide to implement the relationships in Oracle, you must set the this option.
