humm i will check the source and understand how it is done, thanks oleksandr! but... another doubt... today query cache have: query blocks (with query and flags), table blocks (with tables) result blocks (with results) there's any way of two query blocks (or more) link to same result block?
If it would be inexpensive way to detect query with same semantic why do not put them as one query? Why all that complications with linking the same result (and same tables BTW)?
But there is no inexpensive way to detect it (re-printing query is quite expensive if we will do it for each query). I hope it explain everything.
