asp.net mvc 4 中的等待操作超时

Question

I have a table contains 100 columns and 2,000,000 records .

When I am fetching records using stored procedure from that sometimes I am getting "The wait operation timed out." error .When I alter the stored procedure and try to fetch the records, it works fine.

Can anyone let me know what is the best solution for this ?

Answer 1

As vishal Naik has mentioned, SQL server has a default query timeout setting of 30 seconds. A possible solution would be to manually increase this time for a given query and this, while not recommended, should be effective. The code is as follows:

SqlCommand cmd = new SqlCommand(commandText, conn);
cmd.CommandTimeout = 60; // or any other length of time in seconds
/*Any other properties to be modified in the command will come here*/
SqlDataReader dataReader = cmd.ExecuteReader();

Answer 2
