A Simple SQL Update Via PHP


NFD

Recommended Posts

Hi,

What I am trying to do is update one field on one table based upon a match of anoother field on another table.

Here is my initial query (at this stage entered via phpmyadmin):
UPDATE `table1` SET `test_id` = 'table2.test_id' WHERE `group` = 'table2.group' ;

Whilst the query itself runs, it affects 0 rows which is unexpected as there are 2000+ matches.

Firstly I need to know what part of the query am I doing incorrectly?

Afterwards, I want to have a go at making it a query run as part of a php file that does alot of data inserts first.

Any help that can be given would be much appreciated :)
