DELETE transaction with SNAPSHOT isolation level - conflicts another table

Hi,

we are executing the following query in a stored procedure using snapshot isolation level:

DELETE FROM tBackgroundProcessProgressReport
FROM tBackgroundProcessProgressReport LEFT OUTER JOIN
tBackgroundProcess ON
tBackgroundProcess.BackgroundProcessProgressReportID =tBackgroundProcessProgressReport.BackgroundProcessProgressReportID LEFTOUTER JOIN
tBackgroundProcessProgressReportItem ON
tBackgroundProcessProgressReport.BackgroundProcessProgressReportID =tBackgroundProcessProgressReportItem.BackgroundProcessProgressReportID
WHERE (tBackgroundProcess.BackgroundProcessID IS NULL) AND
(tBackgroundProcessProgressReportItem.BackgroundProcessProgressReportItemID IS NULL)

The query should delete records from tBackgroundProcessProgressReport which are not connected with the other two tables.
However, for some reasone we get the following exception:

System.Data.SqlClient.SqlException:Snapshot isolation transaction aborted due to update conflict. Youcannot use snapshot isolation to access table 'dbo.tBackgroundProcess'directly or indirectly in database 'RHSS_PRD_PT_Engine' to update,delete, or insert the row that has been modified or deleted by anothertransaction. Retry the transaction or change the isolation level forthe update/delete statement.

The exception specifies that we arenot allowed to update/delete/insert records in tBackgroundProcess, butthe query indeed deletes records from tBackgroundProcessProgressReport,not from the table in the exception.
Is the exception raised because of the join?

Has someone encountered this issue before?

Thanks,

Yani

Hi,

it looks like this forum is not the best place to ask, since it's dedicated to asp.net

So anybody with idea where i could ask for a solution for my problem?

Thanks in advance!
