登录超时超时错误的第一个SQL查询

Question

I'm running SQL Server 2005 and using IIS for ASP scripts.

I have a problem with sql that is when I run a sql query (exp : http://[host name] with localhost as [host name]) at first time (like when I start my windows) or when the session times out due to being idle for too long, this error happens :

Login Timeout Expired

but after that when I refresh the page, everything will be OK and it works like it should be.

Answer 1

It looks like it takes a long time to run the sproc the "first" time, from then on it only takes less than a sec to execute the sproc. 

SQL Server will generate a execution plan for the stored procedure when it runs the first time, so it will cause a long duration. Then next times SQL can reuse the exection plan so the duration becomes shorter. However a duration of 46secs is abnormal, you can try to create a clustered index on the table, in order to speed up query.
