Re: [PHP] Getting Newest
Why cant u do a query with some subselects and verify the date from each one or do three queryies for the newest one and then compare them with each other... Should be relatively simple... However, it would be better if the date where a timestamp...MHO On Wed, 2002-11-06 at 21:10, Stephen wrote: I have three tables with certain content in each that's added almost daily.

Re: [PHP] Getting Newest
Lighten up! Participation here is voluntary. Maxim gave you a good answer, as you provided no information about the table structure. I'd be wondering why you are using three tables, but that's probably another discussion. Based on what he gave you, and a little study you should be able to figure it out, otherwise query each table in turn pick the most recent according to whatever criteria you use. Have an index on the field which determines most recent, check the max() function and side effects it may have on query speed.

I know that you can select data from multiple tables, but when I do that I get an error.

Re: [PHP] Getting Newest
That's probably because you can't do it in a single SQL statement, but have to use three separate ones and build the logic to check which one is the most recent in PHP. Try outputting the query and posting it to the list, or try inserting a line like this: echo mysql_error(); after you execute your query--that will print out what the MySQL server thinks is wrong with your current query. Hope this helps!

you could make a union of all the records, and order by newest date first: (select id, date, name, text from table1) union (select id, date, name, text from table2) union (select id, date, name, text from table3) order by date desc then select the first record /nick -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
