Question

I am looking for a solution for table ‘A” which structure is:

ID      NAME    SHOWN
1       Eddie    0
2       Marie    1
3       Shawn    15
4       Frank    12
5       Danny    7

I’d like to commit a SELECT on this table so that for each resulted row, the ‘SHOWN‘ would increase, so for example:

SELECT * from 'A' WHERE `ID`>3;

would cause table ‘A’ the following change:

ID      NAME    SHOWN
1       Eddie    0
2       Marie    1
3       Shawn    15
4       Frank    13
5       Danny    8

Only Frank and Danny’s ID is bigger than 3, so the resulting SELECT would yield Frank and Danny and so, their respective ‘SHOWN‘ column is increased by 1

How can I achieve this behavior?

Answer 1

You may update your table with the expected increment then.

UPDATE A
SET SHOWN = SHOWN + 1
WHERE ID > 3
