 * Once a sql statement is compiled, it is cached in {@link SQLiteDatabase}

 * and it is released in one of the 2 following ways

 * 1. when {@link SQLiteDatabase} object is closed.

 * 2. dalvikVM wants to reclaim some memory and releases it from the cache in

 * {@link SQLiteDatabase}.

 * 2. if this is not cached in {@link SQLiteDatabase}, {@link android.database.Cursor#close()}

 * releaases this obj.
