SQL Query : Copy one Column to another column in MySQL

by Gabi Solomon

I wanted to do add a new column to a table and to copy the values from that a diferent to column ( from the same table ) to the new column. And even though i thought of very integrates query’s at first, the solution was quite simple :D ( as always ).

[SQL]
ALTER TABLE `table_name` ADD `new_column` TEXT NOT NULL;
UPDATE `table_name` SET `new_column` = `old_column`;
[/SQL]

Nice and simple.
Cheers

    Depending on your version of mysql you might have to change that a little.  I had to use:
    UPDATE `tablename` SET `new_column` = `old_column`;

    I’m not sure why, or what version but if you are having issues, try it this way also.
