You can view, write, and modify synchronization scripts using Sybase Central. In this section you write the following synchronization scripts:
upload_insert To define how data inserted into the remote database is to be applied to the consolidated database.
download_cursor To define what data should be downloaded from the consolidated database.
Each script belongs to a designated script version. You must add a script version to the consolidated database before you add scripts.
