%OldKeyEqual meta-SQL element

Syntax

%OldKeyEqual(recname [correlation_id])

Description

The %OldKeyEqual meta-SQL construct is similar to the %KeyEqual construct, except that it uses the original values of the record fields, rather than the current values. Since the rules for which values are original and which are current are not very clear, especially for standalone record objects, avoid using this meta-SQL construct. You should use separate records to hold previous values. This can make your code clearer and more maintainable.

Note:

This meta-SQL construct can only be used in PeopleCode programs, not in Application Engine SQL actions. Also, this meta-SQL is not implemented for COBOL.
