Question

I need to copy data from original table and add custom column specified in query

Original table struct: col1, col2, col3

Insert table struct: x, col1, col2, col3

INSERT INTO newtable 
   SELECT * 
   FROM original 
   WHERE cond

and I’m getting this error

Column count doesn’t match value count at row 1

HOW can I insert X value in this single query?

I tought something like this can pass

INSERT INTO newtable 
   SELECT 'x' = NULL, *  
   FROM original 
   WHERE cond

Any ideas?

Is it possible to use *? Because that table has so many columns and X has to be first value

I know this all is bad but I have to edit unbeliveable ugly db with even worse php code

Answer 1

The second statement is almost correct, but instead of 'x' = null, use null x (I’m assuming you want to store a null value in a column named x);

INSERT INTO newtable 
SELECT null x, o.* FROM original o WHERE cond
