Performance Tuning in SQL Server 7.0 by Efficient Data Retrieval
Database Programmers using interfaces APIs like ADO, DAO etc. must remain aware of the result sets they are building. One should try to reduce the size of the result set by eliminating columns in the select list that do not have to be returned, or by returning only the required rows. This reduces I/O and CPU consumption on the SQL Server.
