How do I add to each row in MySQL?
This is probably really easy for most of you but I can’t wrap my head around it. I have a column in my table that is of type Float. I want to modify the value of this column for each row by adding 15. For example, if the column’s value for a particular row is 10, I want to add 15 to it to make the new value 25, and the same for each subsequent row.
I am attempting to use PHP to do this but is there a way to do this just straight SQL?
