Juan A couple of problems I see with that is you will have to reload (or pack) your database more often and it makes it difficult to use in a multi user environment.
What I would do is use the temp table and then create an EEP (when exiting row). This EEP would check “FK” against the “PK”. Granted you would have to write a few more lines of code for the EEP but I believe it would be safe for multi users.

While this might require more frequent PACKing, might this work for you?

I think the same. An opportunity to improve, because temporary table is very usefully to enter data using a form. Thanks.

I just fired up 9.5 and created a temp table and then an FK on it and I got an error. I fired up an old copy of 6.5 and it doesn't work there either, so I assume this has never worked.

(At least for me). This could be a issue?

But you can create the temp table first and then use the alter command to add the FK afterwards. See if that works. Here's an example: ALTER TABLE mpsinvoice ADD FOREIGN KEY (vendornum) REFERENCES vendors Karen -----Original Message----- From: Juan Otazú < <mailto:[email protected]> [email protected]> To: RBASE-L Mailing List < <mailto:[email protected]> [email protected]> Sent: Thu, Feb 14, 2013 1:05 pm Subject: [RBASE-L] - Create FK in temporary table Hi to all, I need to create a temporary table to enter data into a form and validate some PK, FK rules.

(2801) Do not create the temporary table. The only one change has been add "temporary" to line 1. Some issues to connect temporary FK to regular PK ? Thanks in advance.
