Hi,

it happened the second time now that a TIBCQuery doesn't work correctly after a - minor - change in the SQL statement.

When inserting a new record now, it complaints about a missing foreign key value, but that field should be filled by the master-details mechanism.

It worked before the SQL change, and I can't restore the functionality even when changing back the SQL statement.

Last time (with another query in the same project) I had to rebuild the whole query from scratch (with lots of persistent fields), I'd really like to avoid that!

Any ideas?
I use version 3.50.0.18 due to unicode problems in 3.50.0.19 described in another topic (http://www.devart.com/forums/viewtopic.php?t=19480).

Please help to solve that issues!

BR,
Martin

Hello,

If you establish Master/Detail Relationship using the MasterSource, MasterFields, and DetailFields properties, please check that they are not empty and set correctly. And if you use SQL code to establish Master/Detail Relationship, please check that you didn't remove the SQL code that manages this relationship from your SQL statement.
