>>>>>>>Hey gang,

One thing that I run into all the time is nullable fields. I do not like nullable fields, and when I set up my schema I explicitly set the field property to not allow null. When I get the data and the data allows nullable fields exceptions are thrown.

Please let me know if your googling turns up and good utility
