Transferring and summing values from an SQL column

I have two columns in a table, I need the values in column 1 to be transferred and added to the values in column 2.

This can be done with a PHP or is there some easier way to do it?

Original:
ID /  1  /  2  /
1    150   100
2    200   50
3    75    175

Como deve ficar:
ID /  1  /  2  /
1     0    250
2     0    250
3     0    250

There is not much secret to do this in SQL. You didn’t give a lot of details about the table but basically this is to do in all rows:

UPDATE tabela SET col2 = col1 + col2, col1 = 0;

I put in the Github for future reference.

This is adding up the two columns and playing the result on the second, as you say you want.
