SQL formula for blank cells

ScottLeeds

I have a table with some cells that are blank. I would like a zero to populate in the cell instead of them being blank. Is there a simple SQL formula someone could share with me to change the blank cell to a 0 number?

You could do something like this:

CASE WHEN TRIM(fieldname) = '' THEN 0

ELSE IFNULL(fieldname,0) END

This will check to see if it is blank or if it is null (which are two different things) and replace it with 0 if either are true. Otherwise, it will return the existing value.

Alternatively you can combine both together and use a coalesce and NULLIF

COALESCE(NULLIF(TRIM(`fieldname `), ''), 0)
