As a bit of a sidebar, it's a real...

Yeah - I probably could have simplified the question to just "why do aggregate functions return NULL instead of no rows" ... but now that I think about it, my...

So this is a super-old thread to bump, but ironically, I'm working on SSIS packages again after several years, and this exact problem has been coming up again.

I realise now...

That is some very useful info Brian - thanks! The setup I'm trying to create is indeed very similar to yours. Unfortunately since the system is a bit of a...

@desnorton - I don't think sp_ExecuteSQL would actually diminish the danger. If the @WeatherFieldName variable had a semicolon in it, followed by a query - I believe it...

@desnorton - yeah that does seem like it should work better. Still will look rather ugly when dealing with hundreds of columns though.

On the plus side, this is purely for auditing, so there shouldn't...

Alright. Good news. Using the aforementioned approach, I was able to identify the problematic records. Unfortunately, I wasn't able to manually update or delete those records, but after running CHECKTABLE...

Oh! I might have found something!!

I was reading through the original output, and I noticed that at the end there are several records of the following nature:

Msg 8929, Level 16,...

So I did a bit more digging - running DBCC PAGE('mytable', 1, 101273, 2) WITH TABLERESULTS works, and produces the DATA output rows, but since it's a VARBINARY column, I...

Will try the page check option and see if that gets me any more info.

Regarding restoring from a previous backup - to clarify, I do have a working...

Ah. Roger. Will take a look and report back. Thanks!

Hey Numpty,

The output I had pasted is the result of DBCC PAGE against that page. I'm not sure how to interpret that output though; is there something in there which...
