Question

I want to edit an entire mysql table’s row.

I don’t really know mysql at all, so in basic programming this is what I want to do:

from row year in table videos:

The key here is that I want to prepend 19/20 and not add it.

if (year < 50)
    year = year+2000
else
    year = year+1900

How would I go about doing this?

Answer 1

Try this:

UPDATE yourtable
SET year = year + IF(year >= 50, 1900, 2000)

This will work both if your column is an integer type and also if it is a character type.
