Error:

System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. The statement has been terminated. Sample code:

Datacontext context = new Datacontext();
tablename tb=new tablename();

string DeleteQuery="delete from table A";
context.ExecuteCommand<tb>(DeleteQuery);
DeleteQuery=string.empty;


string InsertQuery="Insert into table B(a,b,c,d)Select table from C Union All Select Table from D";
context.ExecuteCommand<tb>(InsertQuery);
InsertQuery=string.empty;

here while executing insert query i m getting an error System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. The statement has been terminated.

If table C and D contain a lot of rows, it may just be taking longer to run the insert than the default command timeout (30 seconds). Add this line before your insert command:

context.CommandTimeout = 240  // set timeout to 4 minutes

By the way, you should be disposing of the context when you have finished with it. The easiest way to do this is:

using (Datacontext context = new Datacontext())
{
    // your code goes here
}
