Re: [PHP-DB] combining the results of mysql query and finding the unique tuples in php

If you're looking for unique results, do a UNION query for all the tables. You'll need to add a dummy field for the 5-field tables, and make sure the field names are the same (use oldfieldname AS newfieldname to make sure everything ends up the correct result column). UNION queries automatically remove duplicates. Toby -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] Connecting PHP to MySQL on Windows
Mike, A plain HOST file should have the commented part at the top, and only 1 reference to localhost unless you are creating Virtual hosts. I would suggest removing the ::1 line BR Gavin On Fri, Jan 7, 2011 at 4:18 AM, michael manning michaelgmann...@gmail.comwrote: Hi, I swapped out 'localhost for '127.0.0.1' in the url but this had no effect.

[PHP-DB] Can't find sqlite_open
Hello, I have a script that is calling sqlite_open, however, sqlite_open can't be found on my systems. I'm running RHEL5 and I get the following relevant output from php -i: PDO support = enabled PDO drivers = odbc, sqlite pdo_sqlite PDO Driver for SQLite 3.x = enabled PECL Module version = 1.0.1 $Id: pdo_sqlite.c,v 1.10.2.6 2006/01/01 12:50:12 sniper Exp $ SQLite Library = 3.3.6 From searching around, it seems like there is a PDO version, which looks to be enabled here, and a older version, which would provide sqlite_open. Is that correct? Thanks! -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
