Hi, I am writing this because of a question on the fora at WebmasterWorld.com.
A user there is having trouble understanding the formula for estimating the memory requirement for a heap table: SUM_OVER_ALL_KEYS(max_length_of_key + sizeof(char*) * 2) + ALIGN(length_of_row+1, sizeof(char*)) The question is at http://www.webmasterworld.com/forum23/1731.htm I have tried to answer, guessing quite a bit, so if somebody knows better, please post a correction here or on webmasterworld. No registration is needed to read the posts. I'll repost relevant answers there if necessary. I have no affiliation with webmasterworld, besides being a user of the site. sql,query -- René Seindal ([EMAIL PROTECTED]) http://sights.seindal.dk/ --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
