We will need a little more information. The table looks sound but is clearly designed to link 2 other tables. If you are failing to insert or update, it seems likely that it is because the data is absent in the foreign tables. Can you confirm? Because without that forgeign data, these rows are pretty meaningless. What is it you are trying to do? -- - michael dykman - mdyk...@gmail.com - All models are wrong.
