SQLExecute takes 100% CPU usage - Microsoft SQL Server

vishal

Hi
I a am executing a stored procedure from C code using SQLExecute . It
takes some time to Execute the procedure. However when I see the
processor usage during that time it shows 100% cpu usage.
Can anyone tell me why SQLExecute uses 100% CPU when running the
stored proceudre.
Thanks

Too little information to say anything useful. The only thing I can think
of is that the stored procedure produecs a huge result set.

If your application is running on the same machine as SQL Server, use
taskmgr to identify the process consuming the CPU. If sqlservr.exe is the
culprit, some query tuning is probably needed. You can examine the
execution plan using Query Analyzer and
modify the proc and/or experiment with indexes to make it more efficient.

If your client application is consuming the CPU, a large result may be to
blame as Erland indicated.

Hope this helps.

CPU Usage jumps to 100%

by: David Schwartz | last post by:

When I run my VB.NET Windows Forms application, the CPU usage jumps up to 100%. If I drop-down a menu, the usage goes down to a more reasonable number, like 0-2%. The same is true when a MsgBox comes up. Has anyone else noticed or experienced this? Why would this be? Is this the norm for VB.NET apps? Thanks in advance.
