Process B can see only data that is committed before it's read transaction is started.
I suspect you are creating a transaction in process B right after connecting to the database that remains open for the lifetime of the connection. This will force Process B to see the state as it was before it's transaction started, i.e. before Process A committed it's changes. -----Ursprüngliche Nachricht----- Von: sqlite-users-boun...@mailinglists.sqlite.org [mailto:sqlite-users-boun...@mailinglists.sqlite.org] Im Auftrag von Gelin Yan Gesendet: Mittwoch, 01. Juni 2016 17:16 An: sqlite-users@mailinglists.sqlite.org Betreff: [sqlite] a question about data synchronization Hi All I have a question about data synchronization. The question is: I have two process A & B. Both of them connect to the same database In Process A insert a value into a table XX and commit. In Process B select from the same table XX and I didn't find the inserted record. If I close the connection in Process B and connect it again, I can select this inserted record. Did I do something wrong? I expect the inserted data is available without reconnection. BTW: I use the latest Sqlite version and WAL mode.
