Please note the the semicolon at the end of an SQL Statement is required. "PRAGMA busy_timeout = 1000000" is not complete SQL. Also, the schema prefix needs to be replaced with the attach name of the database whose properties you wish to query/change. It may be omitted if "main" is desired.

In any case, connections need to indicate if or how long they are willing to wait for the db file to be unlocked. Default is NO. The easiest way is to specify a timeout on the connection. The value needs to be longer than your longest write transaction is expected to run and shorter than the latency required by your application. -----Ursprüngliche Nachricht----- Von: sqlite-users [mailto:sqlite-users-boun...@mailinglists.sqlite.org] Im Auftrag von Urs Wagner Gesendet: Montag, 14.
