There is no record locking in SQLite -----Ursprüngliche Nachricht----- Von: sqlite-users [mailto:[email protected]] Im Auftrag von Clyde Eisenbeis Gesendet: Montag, 06. Februar 2017 14:19 An: SQLite mailing list <[email protected]> Betreff: Re: [sqlite] Retrieve INTEGER PRIMARY KEY
In this case, there is only one record added ... no one else has access to this database. In the past, I have locked a record, so no one else can access that record while it is being modified. Is locking an option in SQLite? Perhaps there is no equivalence to OLE DB ... oledbCmd.CommandText = "Select @@Identity" ... int iKeyID = (int)oledbCmd.ExecuteScalar()?
