Cut it out with the nulls already

[Stomp]

I'm trying to deal with a SQL database (over which I have no structural control) via ODBC. In this database there are numerous fields which are to remain empty the great majority of the time, but they are configured to not allow null values. Instead, an empty string ('') must be used.

So far as I can tell, FileMaker doesn't think very highly of that tactic, and I am slowly being driven mad. Why are you even touching those fields, when they are unmodified and not even on the layout, FileMaker? Why?

If anybody can proffer a method to make FileMaker send an empty string that would be grand. Or make it stop updating unmodified fields. That'd work too.

Also, the fact that the Execute SQL script step doesn't list DSNs on the FileMaker server puzzles me deeply. Throw me a bone, here.
