Question

当我尝试插入此SQL语句时，我收到一条错误消息，指出列数与第1行的值计数不匹配。

INSERT INTO APPLICANT (fullName, Email, CompanyName, Phone, Fax, GovernmentEmployee, Academic, InternationalAttendee, SpeakerOrPresenter, FirstTimeAttendee)

VALUES
('$fullName','$Email','$CompanyName','$Telephone','$Fax', $GovernmentEmployee, $Academic, $InternationalAttendee, $Speaker, $Presenter, $FirstTimeAttendee);

Answer 1

您在INSERT子句中列出了10列，在VALUES子句中列出了11个值。每个子句中必须具有相同的编号。您有$Speaker和$Presenter的值，但只有SpeakerOrPresenter列似乎适用于这两个。

Answer 2

您尝试插入列：SpeakerOrPresenter。
两个不同的值：$Speaker和$Presenter。

因此，您要插入的值多于接收数据的列。

您可以更改查询以使其看起来像这样（将SpeakerOrPresenter列拆分为2个不同的列）：

INSERT INTO APPLICANT (fullName, Email, CompanyName, Phone, Fax, GovernmentEmployee, Academic, InternationalAttendee, Speaker, Presenter, FirstTimeAttendee)
VALUES
('$fullName','$Email','$CompanyName','$Telephone','$Fax', $GovernmentEmployee, $Academic, $InternationalAttendee, $Speaker, $Presenter, $FirstTimeAttendee);

或者像这样（将两个值扬声器和演示者合并为一个）：

INSERT INTO APPLICANT (fullName, Email, CompanyName, Phone, Fax, GovernmentEmployee, Academic, InternationalAttendee, SpeakerOrPresenter, FirstTimeAttendee)
VALUES
('$fullName','$Email','$CompanyName','$Telephone','$Fax', $GovernmentEmployee, $Academic, $InternationalAttendee, $SpeakerOrPresenter, $FirstTimeAttendee);

列数与第1.1行的值计数不匹配
