That's because of an unfortunate historical behavior of sqlite3_step, which now has to be maintained for backward compatibility. When sqlite3_step fails, it returns a generic SQLITE_ERROR code. One has to follow up with a call to sqlite3_reset or sqlite3_finalize, which returns the actual error code that sqlite3_step should have returned in the first place, even though the actual reset or finalize operation succeeds. If you use sqlite3_prepare_v2 function to prepare your statement, you opt out of this legacy behavior and then sqlite3_step returns the actual error code directly, and sqlite3_reset and _finalize behave in a sane way.
