This function never returns any value other than 5, indicating SQLITE3_NULL.  SQLite 3 doesn't have column types, it has column affinities.  Different rows of the same table (and rows resulting from a SELECT) can hold values of different types.  Therefore this API cannot return anything useful, and the method appears to be using SQLITE3_NULL as a placeholder.

The function in useless and should be removed or marked as deprecated in future releases, so as not to give any programmer the false idea that the values returned are useful.
