I'm not sure why you'd want to do that, however you can use Table Hints to
accomplish that... please see BOL for more details.

Just wanted to know if this is possible.
In my stored procedure lets say I fire the below select query :
"SELECT * FROM EMP where EmpName = 'Nilesh'"

and before my stored procedure completes execution. If another user fires
the same select query, his call should wait. However if he fires a SELECT
query for an employee with another name his call should succeed.

Is this possible ?

Thanks
Srihari

Table hints will not work for this.

One possibility: route everything through stored procedures, and use the new
sp_getapplock and sp_releaseapplock. You could use the person's last name as
the resource name to lock, or employeeid, or whatever.
