Hi,

I am having a table with 16 lakhs records in it. Each record contains approximately 50 columns. I am using MSSQL Database. Basically the table contains details of the user's registration details. I have a application built in VB.net which will be selecting a random user_id and then searches for the record which contains that particular id and retrieves the details . The user_id column in my table is set as primary key. My Query is as given below:

SELECT * FROM user_Table WHERE user_id=MyNumber

The value for MyNumber is passed from the application. The problem is that the application takes much time to execute this query.(almost 15 secs for per 1000 users) which is very slow. I need to increase the speed by atleast 50-70%. Currently I am using ADODB recordset for this query. I have also tried using datasets but no improvement in the speed. Is there any way to optimize the SQL Server's performance or do I need to change my query. Please Help...
