0005464: DB Access error after deleting events from Event view (SQL server 2008)
I've tried to delete events from event viewer without selecting any level (i.e. All). As a result I got "DB Access Error" (attached file).

Now, every time people go to login page or when log out from Testlink, the error shows up.

Just go to Event viewer page as admin.
Click on "Clear Events" without selecting any log level or user.
I have attached the log file generated by Testlink and a screenshot.
No tags attached.

Issue seems related to logic used to do the delete ( SQL with IN CLAUSE).
As found by user (see forum) in this particular situation qty of elements on IN was over the limit impossed and managed by MSSQL

On attached error file this is indicated by this message to some extend

The query processor ran out of internal resources and could not produce a query plan. This is a rare event and only expected for extremely complex queries or queries that reference a very large number of tables or partitions.

Some references that can be useful to understand a little bit more [^] [^]

Please replace the file pointed by the commit, retest and provide feedback

I've replaced the original logger.class.php with the new one. To test it, I need time until events are pile up, so I prefer to wait for a week or more then clean events.

Proposed solution has issue with MySQL while working with Postgres, need to find an alternative.

This seems to work [^]
