RE: CLRPFM on file that is foreign key

["Flensburg, Carsten" <Flensburg@xxxxxxxxxx>]

Hello Jeff,

It should not be necessary to remove the constraint, just disable it
temporarily. Here's an excerpt of the recovery part of the CPF3134
second level message text:

Recovery  . . . :

    1 -- Find the dependent files of the referential constraints using
the    
  DSPDBR command on parent file &1 in library &3.  Disable the
referential    
  constraints using the CHGPFCST command or WRKPFCST command on the
dependent 
  files. After the clear operation has completed, use the CHGPFCST
command or 
  WRKPFCST command on the dependent files to enable the referential

  constraints.


Best regards,
Carsten Flensburg

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"?
