Hi everyone, I'm relatively new to SQLite and currently I'm experimenting a little bit with the SQLite database on an embedded system. I want to change the journal mode of a database to WAL. So I did the following:
rc = sqlite3_open(dbPath, &db); rc = sqlite3_exec(db, "PRAGMA journal_mode=WAL;", testCallbackPrint, 0, &zErrMsg); [?] sqlite3_close(db); Unfortunately, after these lines, the journal mode is not changed. The sqlite3_exec function returns SQLITE_OK (0), testCallbackPrint is never called and the error message is empty. Also reading the value of journal mode with ?PRAGMA journal_mode;? leads to the same result (rc=0, callback noch called and error message is empty). It seems as if the pragma is ignored completely, so I tested other pragmas, with the same result. So what am I doing wrong? To compile, I use the following options -DSQLITE_ENABLE_MEMSYS5 -DSQLITE_ENABLE_8_3_NAMES=2 -DSQLITE_THREADSAFE=0 -DSQLITE_OS_OTHER=1 -DSQLITE_ENABLE_API_ARMOR -DSQLITE_DEFAULT_MMAP_SIZE=0 -DSQLITE_TEMP_STORE=0 -DSQLITE_DEFAULT_CACHE_SIZE=500 Thanks. ________________________________ Firma: Capgemini Deutschland GmbH Aufsichtsratsvorsitzender: Antonio Schnieder ?
