Adding Non Data Access Features to UltraLite Applications
Adding synchronization to your application
An UltraLite database cannot have uncommitted changes when it is synchronized. If you attempt to synchronize an UltraLite database when any connection has an uncommitted transaction, the synchronization fails, an exception is thrown and the SQLE_UNCOMMITTED_TRANSACTIONS error is set. This error code also appears in the MobiLink synchronization server log.
For more information on download-only synchronizations, see download_only synchronization parameter.
