Error when attempting to delete rows

I have a log table with no indexes, triggers, or keys. During the course of development, I will clean out the entries by selecting all the rows (in Database Explorer) and hitting the delete key.

Occassionally, I will end up with couple rows (out of many) that won't delete. I get the following error when I attempt to delete the "affected" rows:

A problem occurred attempting to delete row 1.
Error Source: Microosft.VisualStudio.DataTools.
Error Message: The row value(s) updated or deleted either do not make the
unique or they alter multiple rows (2 rows).

I'm also not able to modify any of the data of the affected rows. There don't seem to be anything really special or unique about these affected rows (compared to the ones I'm able to delete). I've tried rebooting the machine and that did resolve the issue.

This is the second time I've encountered this issue. By any chance, is this a known bug with the beta (it's SQL Server 2005 June CTP)? Or is it some else I'm not aware of?

I've also tried deleting the rows using SQL Server Management, same results.

RichardCan you run SQL Profiler to check the different events executing while you delete these records? There must be something happening in the background that is causing all these.|||

Did you ever get the problem resolved? I am having the same problem.

Thanks, Bob

Does the table have a primary key or unique constraint?

|||I just saw this. I'm sure it was resolved since the post was awhile ago, but that error message can occur if there is a constraint which the deletion violates. A common one might be that a field is set to "NOT NULL".
