I’m trying to run one SQL command to update multiple databases. If I copy ‘n paste sql code below directly into PHPMYADMIN it executes just fine, but when I run the sql through php it doesn’t update?

If I run the updates for each database separately via my php script they both update fine, so I’m confused?

What am I doing wrong?

SQL Code:

UPDATE rst.users a, rst.user_type b 
SET a.first_name='Timsd',a.last_name='Lebaronsd',a.password='timsd',
 a.email='tim@dog.comsd', a.user_type_id='5',a.language_code='en_US', 
   a.timezone='Pacific/Midway', create_ts = '2010-07-16 12:33:31' 
WHERE a.user_type_id = b.user_type_id AND b.account_id = 1 AND a.users_id = 90; 

use externalusers; 

UPDATE externalusers.user 
SET fullname="'Timsd' 'Lebaronsd'", emailaddress="'tim@dog.comsd'" 
WHERE rst_id = 90 AND rst_account_id = 1;

    mysql_query() and similar functions can’t execute multiple statements for security reasons.
    Use mysqli_multi_query() if you really want to execute multiple statements with single call.

    P.S. It’s not a PHP feature, but a feature of mysql C API.
