Question

I want to insert multiple rows of data into a MySQL database, but only when my order_id field is unique. This is the current query I have, which doesn’t work. Lets say a record with an order_id of 2 is already in the table:

INSERT INTO conversion
       (user_id,url_id,order_id,sale,commission,transaction_date,process_date) 
VALUES (1,1,1,'32',0.3995,'2010-11-15 12:15:18','2010-11-15 12:15:18'),
       (3,6,2,'*not-available*',0.001975,'2010-11-15 12:15:18','2010-11-15 12:15:18') 
WHERE (order_id <> 3);

Any help is appreciated.

Solved by using REPLACE.

Example:

REPLACE INTO conversion (user_id,url_id,order_id,sale,commission,transaction_date,process_date) VALUES (1,1,3,'32',0.3995,'2010-11-15 12:50:31','2010-11-15 12:50:31'),(1,2,2,'*not-available*',0.001975,'2010-11-15 12:50:31','2010-11-15 12:50:31');
