Is there a single query (subqueries in it are allowed) where I can copy the content of one field into another field, per row. Example:
price, and priceBackup
Records:
45.55
47.77
45.55 copies into priceBackup for that specific row,
47.77 copies into priceBackup for that specific row.
I do have a primary key, auto increment on it under ‘id’.
Thanks guys!
Add a WHERE clause if you only want to do this for some rows.
