Default indexes

hello

stull fuzzy on index retrieval and the order of the indexed fields....

if i have a table with these columns indexed (col1, col3, col4)
and the sql says col1, col4, col3 does the index still get used or
does it stop at col1 because of the order?

i assume always using the exact order of fields in the sql to match the
indexes is the way to be correct but am unsure about different orders
or if the sql has two out of four included but they are either in the
same order or ordered differently.

thanks in advance!

tom
