Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

As you are probably using a SqlCommand for calling the query, you can specify the timeout for that one:

using (SqlConnection cn = new SqlConnection(Configuration.DefaultConnectionString))
{
    using (SqlCommand cmd = new SqlCommand(query, cn))
    {
        cmd.CommandTimeout = 60;
        cn.Open();
        ...


Or specify the timeout for the connection in the web.config (which I will not recommend).

More info here http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlcommand.commandtimeout(v=vs.110).aspx[^]


Cheers
   
You can set the Connection Timeout=value(may be in sec or millisec can't remember) in connection string for the long running query to achieve this
best of luck.....
   
If you give cmd.CommandTimeOut = 0 .Your client API will never time out form SQLSERVER.It will last until the operation is got over.

Hi Rajesh,

Do you really think setting that value to 0 and running forever sql server is a good idea??? I dont yhink so.
