I've run into a small issue with mdb2.
I have a mysql database with a field set to longtext not null.
inserting "" into that field works just dandy when using the mysql_
functions.
However, when using mdb2 - it converts "" to NULL which is NOT what I
want to have happen, and the result is that the execute() fails
because the database table does not accept NULL for that field.
Why does mdb2 turn "" into NULL for a text type when MySQL knows there
is a difference? How do I suppress that?

Why not set a default in the field then, as am empty string and let the
db handle field properly? Having a Not Null with no default is bad db
design.
I need it to error when an attempt to create a record without setting
that field is attempted, but setting the field to an empty string is fine.
Attempting to insert data without defining that field indicates there is
not sufficient information to create a record. Setting that field to a
zero length string however indicates that there is enough information to
create a record. Assuming that no information is the same as an zero
length string is not OK.
Call it bad design if you want, by MySQL knows the difference between
NULL and an empty string, so should my database abstraction layer.
