sqlite3_open_v2() and as UTF-16 in the native byte order for sqlite3_open16(). A database connection handle is usually returned in *ppDb, even if an error occurs. The only exception is that if SQLite is unable to allocate memory to hold the sqlite3 object, a NULL will be written into *ppDb instead of a pointer to the sqlite3 object. If the database is opened (and/or

created) successfully, then SQLITE_OK is returned. Otherwise an error code is returned. The sqlite3_errmsg() or sqlite3_errmsg16() routines can be used to obtain an English language description of the error following a failure of any of the sqlite3_open() routines. The default encoding will be UTF-8 for databases created using sqlite3_open() or sqlite3_open_v2(). The default encoding for databases created using sqlite3_open16() will be UTF-16 in the native byte order. Whether or not an error occurs when it is opened, resources associated with the database connection handle should be released by passing it to sqlite3_close() when it is no longer required. The sqlite3_open_v2() interface works like sqlite3_open() except that it accepts two additional parameters for additional control over the new database connection. The flags parameter to sqlite3_open_v2() can take one of the following three values, optionally combined with the SQLITE_OPEN_NOMUTEX, SQLITE_OPEN_FULLMUTEX, SQLITE_OPEN_SHAREDCACHE, SQLITE_OPEN_PRIVATECACHE, and/or SQLITE_OPEN_URI flags: SQLITE_OPEN_READONLY The database is opened in read-only mode. If the database does not already exist, an error is returned. SQLITE_OPEN_READWRITE The database is opened for reading and writing if possible, or reading only if the file is write protected by the operating sys

Answers STAFF Dave McFarland Treehouse Teacher Dave McFarland Dave McFarland Treehouse Teacher about 1 year ago Sorry error establishing a database connection wamp for the error Heri Mardinal. The version of SQLite in Workspaces isn't the same as in the video. You need to load the database when you open sqlite. https://www.sqlite.org/c3ref/open.html To do that type: sqlite3 database.db Petrov von Petrov 21,890 Points Petrov von Petrov Petrov von Petrov 21,890 Points 4 months ago Apparently the .open command was deprecated, because if you do .help, you won't find the .open command. But If you're using the command indicated by Dave McFarland ─ sqlite3 database.db ─ , you won't need to https://teamtreehouse.com/community/open-databasedb-error open the database anyway, because it will already be loaded. You can safely skip that command and jump to .tables, and follow along from there.
