Question

我正在使用petapoco。加入6张桌子我得到例外：不能在2张桌子之间分割点，如果有人对此有任何想法，请告诉我。

//数据访问

public static List<UserAccountsPOCO> GetFavouriteList(UserAccountsPOCO objUserAccountsPoco, int CurrPage, int PageSize)
        {
            var context = new PetaPoco.Database(Connection.connectionstring);
            SqlQuery =

            return obUserAccountPoco;
        }

Answer 1

列顺序必须与传递给Query方法的数组中指定的类型匹配。例如

根据您的专栏，它应该是：

1. UserAccountsPOCO
2. QualificationPOCO
3. MartialStatusPOCO
4. BuildTypePOCO
5. UserImagesPOCO
6. FavouriteListPOCO

但你有：

1. UserAccountsPOCO 
2. FavouriteListPOCO 
3. QualificationPOCO  
4. MartialStatusPOCO
5. BuildTypePOCO
6. UserImagesPOCO
