There is no way not to use transactions. If you don't start transaction explicitly, implicit transaction will be started for each statement. This ensures that when a statement fails (e.g. because of constraint violation), it has no effect and that you don't end up with corrupt database when the write fails (because application crashes, power fails or whatever). > is the data safe from failure if I turn off the journal? No. http://sqlite.org/pragma.html#pragma_journal_mode clearly says, that if you set PRAGMA journal_mode = memory or PRAGMA journal_mode = off and the application crashes while writing the database, the database will likely go corrupt. > The insert isn't concurrent Locking is independent of journal mode. > and I'm using System.Data.SQLite (.net) The above applies to using sqlite from any language. The bindings all use the same library. -- Jan 'Bulb' Hudec <b...@ucw.cz> _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
