Question

Just a quick and simple question:
I am using php and am looking to update a field with values from a field in another table.
I have the syntax working fine in mysql, but can’t seem to get it right in php.
example

tbl_1:
UID    |    Message    |    customer_email

tbl_2
AccountNumber    |    customer_email

update tbl_1 
set tbl_1.Message = REPLACE(Message,'FOO',AccountNumber) 
from 
tbl_1 inner join tbl_2 on tbl_1.customer_email = tbl_2.customer_email;

Any ideas?

Answer 1

$sql = "update tbl_1  set tbl_1.Message = REPLACE(Message,'FOO',AccountNumber)  from  tbl_1 inner join tbl_2 on tbl_1.customer_email = tbl_2.customer_email; ";   
$result=mysql_query($sql) or die("$sql: " . mysql_error());

Your query should work as is. The PHP doesn’t manipulate the SQL, it just passes it on.

Also, remember that if you are passing user input to the database, always sanitize it (or use PDO and save yourself).
