Hello everyone,

I have a table called pollData. It will always contain only 1 row. It has columns option1, option2, option3, option4, option5 each of type int. In the beginning, these columns have 0 as their value. How do I add 1 to any column, say option2? I mean do i retrieve the value of that column first, perform addition, and store back, or is there any auto increment function?
