Sybase Anywhere provides a possibility, which different clients with different date sources can be synchonised with a central DB server. Its manual is here: http://manuals.sybase.com/onlinebooks/group-pbarc/conn5/sqlug/
The SQL of Sybase is a little different from the standard SQL, for example:
>> Clearing a table "dummy"
>> Output to a file
select * from dummy;
output to 'dummyfile.sql'
