regex

Hi,

I have this SQL condition that is supposed to retrieve all rows that satisfy the given regexp condition:

country REGEXP ('^(USA|Italy|France)$')

However, I need to add a pattern for retrieving all blank country values. Currently I am using this condition

country REGEXP ('^(USA|Italy|France)$') OR country = ""

How can achieve the same effect without having to include the OR clause?

Thanks, Erwin
