插入查询时出错

Question

我正在尝试插入sql数据库但是我一直收到错误

以下是提到的查询：

 str2 = "Insert into [Snaps](Loc_city,Loc_state,Loc_country,Edu_Hist1,Work_Hist1) values (Loc_city= ' " + soap.data[i1].current_location.city.ToString() + "', Loc_state='" + soap.data[i1].current_location.state.ToString() + "', Loc_country='" + soap.data[i1].current_location.country.ToString() + "',Edu_Hist1='" + soap.data[i1].education_history[0].name.ToString() + "', Work_Hist1 ='" + soap.data[i1].education_history[0].school_type.ToString()+"')";
                     cmd = new SqlCommand(str2,con);
                     cmd.ExecuteNonQuery();

请帮忙

Answer 1

您的值列表中不需要'Loc_city = ...'。它应该只是：

 str2 = "Insert into [Snaps](Loc_city,Loc_state,Loc_country,Edu_Hist1,Work_Hist1) values ('" + soap.data[i1].current_location.city.ToString() + "', '" + soap.data[i1].current_location.state.ToString() + "', '" + soap.data[i1].current_location.country.ToString() + "', '" + soap.data[i1].education_history[0].name.ToString() + "', '" + soap.data[i1].education_history[0].school_type.ToString()+"')";

Answer 2

您不需要值Loc_city=。 只需传递以逗号分隔的值

Answer 3

VALUES子句应该只包含实际数据，插入的顺序和列已经在INSERT语句中指定。

示例：

INSERT INTO testTable（colA，colB，colC） VALUES（'VarcharCol'，22，'VarcharColC'）

Answer 4

插入值时删除字段的名称： 从：

values (Loc_city= ' " + soap.data[i1].current_location.city.ToString() + "', Loc_state='" + soap.data[i1].current_location.state.ToString() + "', Loc_country='" + soap.data[i1].current_location.country.ToString() + "',Edu_Hist1='" + soap.data[i1].education_history[0].name.ToString() + "', Work_Hist1 ='" + soap.data[i1].education_history[0].school_type.ToString()+"')";

要：

values ('" + soap.data[i1].current_location.city.ToString() + "', '" + soap.data[i1].current_location.state.ToString() + "', '" + soap.data[i1].current_location.country.ToString() + "', '" + soap.data[i1].education_history[0].name.ToString() + "', '" + soap.data[i1].education_history[0].school_type.ToString()+"')";

考虑使用SqlParameter with your SqlCommand或string.format()来清理查询。
