How to make a SQL run longer?

Hell All,
To reproduce one of our cusotmer's probem, I need to make the SQL to
run for more than a minutes before it returns the result set. I do not
have large amount of data in the database to simulate the dealy.

Is there a way in SQL to cause the delay while returning the result
set

Thanks for the help.

Regards
RajWAITFOR will do that.

select getdate()
waitfor delay '00:01:00'
select getdate()

Thanks for replying. My challange is that I can pass only one SQL
statement at at time. Is there a function that I use like this:

select a, b, c
from table_a a, table_b where a.cid = b.cid and delay(0:0:1)

Thanks.

maybe you should tell us WHY you need a delay, because most in the eyes of
most people a SQL-server must be fast, so no DELAY's...

I hink when you do give that information, there might be another way to
solve your problem.

You could write one that calls xp_cmdshell and the uses a wait command
in the shell.

But hopefullly you can also access the database from a regular query
window. In such case you can start a transaction that locks one of the
tables in your query. After a minute you commit/rollback that transaction,
so that the other process is let go.

Our is an reporting application that can connect to either SQL server
or Oracle, retrieve the data and prsent the data over the web for the
end users. This application has the option to preview the data while
developing the report. Duing the preview, if the query takes more
than
one minute than our application hangs.

I need to reproduce this behaviour but unfortunately does not have
enough
data in my database to create the one minute.

Thanks.
Raj
