p.s., if you reply, kindly CC me as well. hi, i have the following SQL query
select col1 from table1 where col2 = 'xxx' or col3 = 'xxx' how can i get rid of this OR? due to my table design and the logic involved, i have to check both these 2 columns (in a search function). i cannot concaneate them to make a third column because i need to check for exact match but for both the columns. the EXPLAIN gives me the "ALL" type, which of course is not optimal. if i remove the OR in the above SQL, and make only one condition, then this EXPLAIN comes back as "const". this is ideal! and what i want. so what can i do to replace the OR? in a curious fit, i tried : select col1 from table1 where 'xxx' in (col2, col3) and to my surprise this works!!! but the EXPLAIN returns "ALL" again. so it is useless.. thanks in advance for any insight/ideas! .ep __________________________________________________ Do You Yahoo!?
