I am using phpMyAdmin to simplify the DB administration, but yes
I have setup the table as you are suggesting. The problem as I see it
is that the value of the incoming data is ' ', and when this is inserted
into the database it becomes '0'. The problem is if I test against this
value now, the input value is still ' ' and the database is '0'.
The goal is a change log on this table. I am accomplishing this
by reading each line of the incoming file and doing a select on the key
field to grab the database entry as an array. Then I work through the
database array comparing it's contents to the incoming file data array.
If a difference is discovered, then the database array is populated into
the change log table and the incoming file data array is populated into
the live table. Obviously this strange behavior is disrupting this
change log testing.
Thanks again for any feedback.

Hi,
Not sure what you're trying to achieve,
Are you trying to have a blank(' ') instead of '0'?
or are you trying to actually store as 'NULL'?
Have you tried
create table table_name (
field datatype(size) default as 'NULL',
...
)
?
