What causes a journal file to be created in SQLite?

Question

I started noticing a weird behavior with my SQLite queries for my iPhone application. Whenever I execute an \"INSERT\" statement, a journal file is created beside my db fil

Answer 1

As Joe said, the journal is created when a transaction is started and SQLlite creates one for you when you start a statement.

To clear out that journal and make sure that the statement was committed to the db use:

sqlite3_finalize(insertStmt);   

Before your close.

The .journal file will go away and all your data will be nice and safe in your DB.

Hope this helps.
