Hi All,
We're running SQL Server 2000, SP3.
I have a stored procedure that consists of a single Select statement.
It selects a bunch of columns one of which is a column of data type
TEXT.
SP takes 30 sec to run which causes timeouts on the Front End.
When I comment out the Text column from the select it only takes 1
Sec.
Is there anything I can do about it? I know I can't index a Text
column. It's also not used in the where clause, so no need for
Full-Text Search.
But we absolutely have to have it in the Select clause.
Thanks for the help in advance.

Return less rows at once?
It's probably slow because it's sending back a lot of data -- send back less
data and it will be faster.

Performance wise Less is More but lso try deferring the select of the text.
If the front end displays a list of entries (e.g. Grid) and the text in a
seperate control, which gets displayed as the grid is scrolled down ...
retrieve into the grid and only select the first one. As the user changes
the selected row, retrieve just the displayed text data item.

I agree, but remember, there's also a tradeoff due to network round
trips, server connection, etc -- it takes time to retrieve any data every
time you make another request to the server. So the OP should test very
carefully to make sure that network traffic doesn't slow down the app when
more db calls are made. This is especially important in web-based
situations.
I assumed that he would test any advice given. The root of both of our
answers is less is more.
Perhaps I need to create a signature block for my postings - Any feed back
on the following would be appreciated.
1.Your mileage may vary.
2. Past results do not guarantee future returns.
3. Some settling of contents may have occurred during shipping.
4. This free advice come with an infinite money back guarantee, (as any
number time zero remains zero).

Personally, if I were to create that, it would have something along the

I am getting records from a db and displaying the records to the user
