Home -> Community -> Usenet -> c.d.o.misc -> index on multiple columns vs multiple indexes on single column
Could someone explain (or point out the relevant documentation about)
situations in which you would want to index several columns vs making
multiple indexes, one for each column? Also, I understood that the
order of columns in a multi-column index was important, but I do not
understand why.
