Asp.Net Gives a Timeout Error While Running a Stored Procedure

Question

I am using asp.net, .NET 3.5, C#, and SQL Server Express 2005.

I have created a stored procedure in SQL, and when I run SP from SQL server it takes less than 1 second to return results. I have also tried that query in query analyzer and it also gives me results in less than 1 second. But when I try to call this SP from .NET (C#), it takes a long time, and then gives a timeout error.

Here is the code I am using to call the stored procedure:

SqlConnection con = new SqlConnection();

con.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
con.Open();

SqlCommand command = new SqlCommand("spReport_SiteUsage_KP", con);

command.CommandType = CommandType.StoredProcedure;

command.Parameters.Add(new SqlParameter("@fromDate", SqlDbType.DateTime));

command.Parameters.Add(new SqlParameter("@toDate", SqlDbType.DateTime));

command.Parameters[0].Value = Convert.ToDateTime(DatePicker1.SelectedDate.ToShortDateString());

command.Parameters[1].Value = DatePicker2.SelectedDate;

int i = command.ExecuteNonQuery();

con.Close();

Store Procedure :

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[spReport_SiteUsage_KP]
    @fromDate datetime = null,
    @toDate datetime = null
AS
    truncate table dbo.RPT_SiteUsage

IF (@FromDate is not null and @ToDate is not null) --Hourly Report, grouped by hour
Begin   

    insert into RPT_SiteUsage 
    select '' as ReportType, 
    'Site Usage for '+ datename(mm,@fromDate)+' '+datename(dd,@fromDate)+', '+datename(yy,@fromDate) + 
    ' To '+datename(mm,@toDate)+' '+datename(dd,@toDate)+', '+datename(yy,@toDate) as ReportTitle,
    min(@fromDate) as FromDate,max(@toDate) as ToDate,

            inner join dbo.UMM_Cookie c on s.CookieId=c.CookieId
            where ua.actiondate< @fromDate --this is the from date
        group by UserId,ua.sessionId    
         ) Old on ua.sessionId = Old.sessionid
    left join
        (select ua.sessionId,count(distinct(uaP.PageEntryId)) as PagesVisited
        from dbo.UMM_UserAction ua,
        dbo.UMM_UserActionPageReview uaP 
        where ua.UserActionId=uaP.UserActionId
        and ActionDate between @fromDate and @toDate
        group by ua.sessionId
        )pVisited on ua.sessionId = pVisited.sessionId
    where ActionDate between @fromDate and @toDate

    IF (select count(*) from RPT_SiteUsage)=0
        insert into RPT_SiteUsage 
        select '(1 day)' as ReportType, 
        'Site Usage for '+datename(mm,@fromDate)+' '+datename(dd,@fromDate)+', '+datename(yy,@fromDate) + 
        ' To '+datename(mm,@toDate)+' '+datename(dd,@toDate)+', '+datename(yy,@toDate) as ReportTitle,

Timeout on what line? con.Open (probably) or command.Execute? — JP Alioto

Another idea, the TimeOut of each SqlCommand is also controlled individually, so, you can control it with CommandTimeOut property.

command.CommandTimeout = 120;

However, I would check the execution plan to see where is it wasting or hogging db resources, I suggest this just for experiment, not on production.

Well - I would say there's an error in your connection string. Please check it.

If it takes long before the query returns an error, there is probably something wrong with your connection (string).

Ah, more info. Can you publish the Exception details?

It could be the fun issue with a bad query plan cached on the proc. Especially if the guts of the proc just as a Query in Query Analyzer runs fine. Check this link out on how to resolve the situation: http://www.mssqltips.com/tip.asp?tip=1304
