OLE DB Error when performing DELETE

[jeremyw]

I'm attempting to delete rows from two of my tables. The tables have a one-to-many relationship, and I've attached a screenshot of their definition and relationship so you can see how they're structured.

The second table has a foreign key into the first, and the "ON DELETE" rule for this relationship is set to "CASCADE". In other words, when I delete a row from the first "parent" table, any linked rows in the second "child" table should automatically be deleted as well. This is in fact what happens when I perform simple SQL DELETE statements from the MS SQL Server Management utility.

However, when executing the same commands via a TMSSQL component from the SDAC library, I get the following OLE DB error. Based on MS documentation, the error code provided means the following:

0x00040EDC 265948
Updating this row caused more than one row to be updated in the data source

Any idea why the delete won't work properly using the SDAC component? I can always go and delete the linked rows first from the child table, but why should I have to if I've properly established an ON DELETE CASCADE relationship?

I can not reproduce the problem.
Please send me a complete small sample to dmitryg*devart*com to demonstrate it, including script to create database objects.

Also supply me the following information:
- the exact version of SDAC. You can see it in the About sheet of TMSConnection Editor;
- the exact version of your IDE;
- the exact version of SQL server and client. You can see it in the Info sheet of TMSConnection Editor.
