Question

当我想在数据库的表中插入记录时，出现以下错误消息：insert语句中的列少于values子句中指定的列。这是我的SQL语句：

dm.qr_emp.SQl.Add( 'insert into emp_per(nom, prenom, date_naiss1, cle_ccp,nomf,prenomf,' +
  'lieu_naiss,sex,adr,id_corps,id_fonction,id_categ,montant_resp,' + 'compte_ccp,etat,sal_base,id_grade,id_banque,id_degree,sal_unique,' +'pfc,iep,num_social,sal_principale,ind,salaire,montant_irg,' +
  'ss,nbr_enfant,nbr_enfant_sup,bource_f,irg,retenue) '
);
dm.qr_emp.SQL.Add
('values('+quotedstr(edit1.Text)+', '+quotedstr(edit2.Text)+','+quotedstr(formatdatetime('yyyy-dd-mm',datetimepicker1.DateTime))+', '+

edit4.Text+','+quotedstr(edit5.Text)+','+quotedstr(edit3.Text)+','+quotedstr(edit6.Text)+','+quotedstr(ComboBox3.Text)+','+quotedstr(edit8.Text)+','+ inttostr(id_corps)+','+ inttostr(id_fonction)+',

要插入记录时，列数必须与插入值的数目相同。例如：

INSERT INTO Employees(Name, City, AccountNumber)
VALUES ("John", "London", "0098737602230")

例如，下一个语句将失败，因为列名和插入值的数量不匹配。

INSERT INTO Employees(Name, City)
VALUES ("John", "London", "0098737602230")

INSERT INTO Employees(Name, City, AccountNumber)
VALUES ("John", "London")

我建议您对代码进行一些整理。当前的声明是人类无法理解的，并且会导致错误。
