My xFileControl() method has actually returned a SQLITE_OK and not as stated in the documentation, a SQLITE_NOTFOUND. I fixed it and now all the PRAGMAs worked fine.

I In that case, as you have a custom vfs, could you check if it's your vfs that is handling those pragmas? The documentation at "http://sqlite.org/c3ref/c_fcntl_busyhandler.html#sqlitefcntlpragma"; describes that when you run a PRAGMA statement on a database, sqlite will call the xFileControl method of the vfs file handle (as given in a sqlite3_io_methods structure) with SQLITE_FCNTL_PRAGMA as the second parameter. If that method returns SQLITE_OK, then sqlite will assume the vfs has handled the pragma, and will not handle it itself. This could cause pragmas to fail silently. -- Ambrus _______________________________________________ sqlite-users mailing list sqlite-users at mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users ________________________________ Firma: Capgemini Deutschland GmbH Aufsichtsratsvorsitzender: Antonio Schnieder ?
