Re: [PHP] Getting two queries into one result set
Hi guys, Thanks for your replies but neither UNION or REGEXP can be used with SHOW TABLES... Any ideas?

[snip] Thanks for your replies but neither UNION or REGEXP can be used with SHOW TABLES... [/snip] SHOW TABLES is such a limited query and allows for such primitive conditionals that you would probably have better results doing two queries and looping them into the same output -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Getting two queries into one result set
You don't say how many tables you have, how they are named or anything outside of the query itself. Assuming that not all your tables are named PID_* how about simply doing SHOW TABLES LIKE '%PID_%' and selecting appropriate results within the php script using strstr or regular expressions? SHOW TABLES is (normally) such a quick query returning a larger result set shouldn't be too much of a problem, should it?

If it is, then you should rework your db to reduce the number of tables :) Alternatively use multi-query with use_result and more_results. If it's concise code that you are after, then set up all the search strings in an array, and pass this through a loop that performs each query at a time and cats the results into a new array.

[PHP] Getting two queries into one result set
Hi, I have a query where I select all table names where the table name has PID_1 in i.e. SHOW TABLES LIKE '%PID_1%'; However there may be cases where I need to search for tables where the table name is PID_1 or PID_2. In MySQL this can't be done in one query, so how can I do two queries and combine the result set so I can loop through it?
