Copy data from one field to another on every row

Question

So I\'ve got:

id    number
 1      0
 2      0
 3      0

Is there a sql statement to copy everything from id into number?

Answer 1

You can use an update statement and reference the columns. Just do the following:

update mytable set number = id

That sets number equal to id on each row. Enjoy!
