Multiple Inserts with MySQL

Andy Jarrett posted this technique for insterting multiple rows (bulk insert) in one SQL statement a few months ago. It's a handy trick:

INSERT INTO x (a,b)
VALUES 
 ('1', 'one'),
 ('2', 'two'),
 ('3', 'three')

I tried that on a couple hundred thousand rows today, and I got an error that my statement was bigger than the Max Allowed Packet size in MySQL. So keep that in mind when using. You can either change the setting, or go about it a different way.

This is all good and well if you are inserting the exact same information into multiple tables, but what if you want to insert into 2 or more tables the information from ONE form, but each table has different sets of information. You have to then do it as 2 or more seperate INSERTS :(

hi, how do you insert data from one record's column into another record's column in the same table. p.s the columns from where and to where data is being transfered is the same column in the same table.

OK, so how can I do this with CFQUERY? When working with MySQL (PhpMyAdmin), this works fine--> [ INSERT into table (colA, colB, colC, colD) VALUES (1958, 106165412, 'stuff', 1), (1958, 106165412, 'stuff', 1), (1958, 106165412, 'stuff', 1), (1958, 106165412, 'stuff', 1), (1958, 106165412, 'stuff', 1) ] But if I wrap it in CFQUERY, ColdFusion (BlueDragon) gives an error. Why?
