#SQLite该查询语句不符合我的想法。我该怎么办

Question

const static char* QUERY_UPDATE_ROUTE_ADDRESS = "UPDATE [PRouteAddrTable] SET [addressLanguage] = ?, [iso] = ?, "   \
                                                "[country] = ? , [state] = ?, [city] = ? , [cityCenter] = ?, "      \
                                                "[street] = ? , [street2] = ?, [houseNo] = ? , [zip] = ? "          \
                                                "WHERE RouteID = ? AND WptUseType = ? AND Lon = ? AND Lat = ?";

执行此查询时，表为空。因此，我认为即使执行查询语句后，表也应该为空。但是有一个记录。我似乎在想错。

请帮助我
