RE: CLRPFM on file that is foreign key

Jeff,

One SQL way would be to cascade the deletes of the header records down to the detail records instead
of restricting them.

Then just CLRPFM header and both tables are cleared.


HTH,

Charles

Subject: CLRPFM on file that is foreign key

How does one do a CLRPFM on a table that is the target of a
foreign key constraint?

It's a header/detail arrangement with the following constraint:

ALTER TABLE JEFF/detail
CONSTRAINT gottahaveaheader FOREIGN KEY ( dorder# )
REFERENCES header ( horder# )
On Delete Restrict
On Update Restrict ;

The CL stream has the following:

CLRPFM DETAIL
CLRPFM HEADER

Since I clear the detail first, I thought it would be OK to
clear the header, but it won't allow it. I get CPF3134 which says:

Message . . . . : Referential constraint error processing
member HEADER.
Cause . . . . . : The operation being performed on member
HEADER file
HEADER in library JEFF failed because of reason code 1. The
reason codes
and their meanings are:
1 -- A clear operation was requested and the file is a
parent file with
established and enabled referential constraints.

Note that the constraint in question is from file DETAIL
which I just cleared, so it's empty. (I confirmed it was
that file's constraint by removing the constraint.)

Do I have to remove the constraint and re-add it? Or is
there an "SQL way"?

Thanks.
