group:How to make a SQL run longer?
sql server (alternate):
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 Raj

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. Raj
WAITFOR will do that.
select getdate() waitfor delay '00:01:00' select getdate() Roy Harvey Beacon Falls, CT [quoted text, click to view] On Wed, 27 Jun 2007 11:16:26 -0700, Raj <jkamaraj@gmail.com> wrote:

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

With your suggestion, I was able to do what I want. Here are the steps I followed 1. Create the following SP in my SQL server. CREATE PROCEDURE byroyalty1 @percentage int AS begin transaction select au_id from titleauthor(tablockx) WAITFOR DELAY '0:1:0' commit transaction GO Note the exclusive lock for the table titleauthor 2. Execute this procedure from SQL Query analyzer just before I run my application. Now my application has to wait longer atleast a minute before it gets the resultset from the databse. Thank you for your help. Regards Raj

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. -- Erland Sommarskog, SQL Server MVP, esquel@sommarskog.se Books Online for SQL Server 2005 at http://www.microsoft.com/technet/prodtechnol/sql/2005/downloads/books.mspx Books Online for SQL Server 2000 at

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