Thanks for the info. I have an R2 infrastructure where I work, but no archiving database to query against, so it has been difficult to test the issues that others have had since my post.

Guh. Looks like my code got mangled by the site removing HTML.

The correction to the query should be such that LcsLog.dbo.Messages.Toast DOES NOT EQUAL 1. In SQL this is a “less than angle bracket” and a “greater than angle bracket” with no space between.

Or you could change the query to LcsLog.dbo.Messages.Toast = 0, which would probably be better and more precise, in hidsight. Either way. Sorry for the confusion.

Hey guys, try changing lines 62, 66, 78, and 82 of the SQL queries where the toast messages are being filtered out to say ‘and LcsLog.dbo.Messages.Toast 1′ as opposed to ‘and LcsLog.dbo.Messages.Toast Is Null’ — without the apostrophes, of course.

The toast column is a bit value column that also accepts nulls. However, OCS 2007 R2 appears to log them as bit values only. This is why the queries were (correctly) coming back with no data.

PS
I’m no DBA, so forgive me if I my terminology is incorrect.

Having the same problem. It appears that the query for the SQL database isn’t returning any results and that’s why it’s failing. I’ve verified the converstations exist by using an older version of this script. How do we fix this?

We’re getting a similar thing to Kernel. Was working fine a couple of days ago, now we’re getting:

Hi Scott,

I tried the script and it errors out on me. The methmod .getData() doesn’t appear to be working. Now when i use the .get_InnerText() method, it appears to get the body text. Any idea why this might be?
