Home -> Community -> Mailing Lists -> Oracle-L -> unknown value
Hi all:
This is probably a simple question, but then again may
be not. We are developing an application and will be
loading data into bunch of tables. We will have a
situation where some of the values will not be
provided
for various reasons. We don't want to make them NULL
because some of these fields are part of a PK so we
decided to come up with some values to mean "unknown".
Is there any reason NOT to use a question mark as such
a value for char strings? To me it sounds like a
character is a characted and question mark shouldn't
be
treated differently then, say, an "X". Is there a
situation when having "?" in a character field instead
of a letter can create problems?
thank you
Gene
