Hi All, If I got one table A_table with many columns, and a second table B_table is the same but with just primary field and unique field... How much meaningful is the time difference between these queries? 1. SELECT unique_field FROM A_table WHERE prim_field='val'; 2. SELECT unique_field FROM B_table WHERE prim_field='val';
If I split A_table into some tables, and define C_table to be MERGE on the A_table pieces. Is the time difference between selecting from A_table or C_table is meaningful? thanks in advance, -Lorderon. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
