Re: [PHP-DB] mysqldump via php
Thanks all for the help! exec() seems the best option.

My thought was to use mysqldump, write the data to a file and save the file. However... $query=mysqldump $dbase; $result=mysql_query($query) or die(mysql_error()); ...immediately results in an error in your SQL syntax near mysqldump [database name]. The reason I want to do a MySQL back up via php is that I have a web application in which the user can archive a project, which involves moving a lot data from one set of tables to another set of tables. The user can also delete a project, which removes lots of data from the DB altogether. Although there are lots of Are you sure you really want to do this? messages the user must click upon, I am sure I will eventually get a user telling me she accidentally archived/deleted stuff and can I help. So, my thought was to do a incorporate a mysqldump in the archiving/delete page. That way there would be a snapshot of the pre-action db, making it easy to put things right. Can you help with my query - or by suggesting an alternative solution? Thanks, Jeffrey -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] LIMIT
If you're using MySQL then: SELECT SQL_CALC_FOUND_ROWS * FROM aTable LIMIT 5 SELECT FOUND_ROWS() It's in the mysql documentation under SELECT syntax I believe.

Is there a way to find out that 100 rows would have been returned if there was no LIMIT clause, by using only Query #2 and maybe a PHP function on the $result?

RE: [PHP-DB] LIMIT
Thanks, but that's an additional query. I was wondering if there may be a PHP function that can operate on the $result or perhaps $link of the single query that uses a LIMIT clause and have the information [count(*) had there not been a LIMIT clause count_no_limit(*) maybe? even though there was a LIMIT clause]. Something like mysql_info. Regards, Dwight x2407 -Original Message- From: Frank M.
