Subject [IBO] How set default to blank string?
Author G. Allen Casteran
Ihave column defined as VARCHAR(30) DEFAULT '' (CHECK VALUE IS NOT NULL).
IBO tries to Insert a NULL for fields where the
user did not make an entry on my entry form. That causes the check
constraint to fail, since InterBase is not using the default.

Therefore what is the best way to set the default values of an empty string
if I am using a TIBOQuery?
