I am working in a controlled environment, so I can rule out changes made to
data.
I created an eo model of a single table, just because I wanted to
incrementally test the whole premise of "SQL Server - EOModeler". And to be
super cautious I only tried updating one record, one field.
I've never tried turning SQL logging on, can you point me to the right
location? (is it in xcode?)
I really appreciate your help :)
