This isn't DMO but it compliments the other scripts.
Given a table it will script all the data as insert statements.
This can be used to populate a table or to record changes e.g. in lookup tables.
It uses sp_CreateDataLoadScript (the remote version) which can be found under tsql scripts on this site)
