dbsync_srvapp.central_set_sync_timestamp()
Registers the point in time of last central data refresh.
Syntax
FUNCTION central_set_sync_timestamp()
Usage
The function registers the point in time of the last fetch of table row(s) into the application
memory. Call this function before central_change_init()
, to
set the timestamp of the last data refresh in the current DB sync server-side app, to check for
other user changes when calling the register_central_*()
functions for a given row.
If more recent changes have been done by another user, the registration function will return an
error. The DB Sync server-side app code should then fetch fresh data, re-do the modifications, and
re-initiate a central change process taking other user changes into account. If this function is not
used, the registration functions ignore changes done by other users.
