ok sorry heres hte point i trying to make. version 1.2/libmergeant 
attempts to be what bonddb is. Its the same feature set.  I could rip 
out bonddb and replace it with libgda and it would do the same thing 
without to much code to rewrite.  Now thats feasible if it was more 
mature with update/insert row stuff, but i know bonddb works and i've 
been using it for years so i will proberly continue to use it in 
immeditate future. but if i am going to get bonddb to talk to libgda 
then i want to talk at a lower level, its costly resource wise to have 
libgda and bonddb doing the same job and one is just a wrapper to 
another.  I can just talk to libgda datamodel fine but it could problems 
later on with version > 1.2 with bugs if both libgda and bonddb 
libraries were trying to do the same thing. Should the 1.2 changs be at 
a higher abstraction layer in the api?

so gdacommand is like an update or insert?

its more of a tool though.

be nicer if that was in api so i know that it was specifically freed for 
non-gobject stuff. talking more so of structures.
