Apologies that this reply is coming possibly a bit late. My experience is essentially limited to Postgres, Informix, and Foxpro, the last in which I haven't done any development in a while. General procedure that I know of is: 1 - dump the schema of one to a file and tweak it so that it conforms to the standards of the target database server 2 - dump the data to a pipe-delimited text file 3 - use the schema from the source database program to create a database in the target database program/server 4 - import the pipe-delimited data. In the case of Informix and Postgres, both have utilities (dbschema and pg_dump with the -s flag, respectively) which allow you to output a databases schema to stdout or a file. I know that with Foxpro 3.0 there was some sort of schema utility included somewhere. Informix has an SQL command called UNLOAD which allows you to dump data to pipe-delimited formats; pg_dump -a dumps the data in postgres; COPY in the postgres monitor gives you a little more control as to the format of data dump. Informix's syntax is a cleaner implementation in this regard, though. Postgres's pg_dump is great, though, for backing up a whole database w/ schema and restoring it. So I only gave you half an answer since I didn't address your MS Access or Filemaker pro issues. I suspect though you can do exports and control the format in some way. > Thanx, Steve. -- Max Pyziur BRAMA - Gateway Ukraine pyz@brama.com http://www.brama.com/
