Question

我一直在执行此触发器，在插入同一个表时进行合并，但显然我一直收到此错误：

Column name or number of supplied values does not match table definition.

我的触发器：

create trigger [dbo].[Updated_table1]
on [dbo].[table1]
instead of INSERT
AS 
BEGIN
set nocount on;

IF(SELECT COUNT(*) FROM INSERTED) = 0
    RETURN;


merge into  [dbo].[table1] with (HOLDLOCK) as d
using INSERTED as i 
on (i.[primarykey] = d.[primarykey])
when not matched then insert 
values ('...','...');

END

有什么想法吗？

Answer 1

在insert语句中明确提及Target和Source列名....

像这样........

create trigger [dbo].[Updated_table1]
on [dbo].[table1]
instead of INSERT
AS 
BEGIN
set nocount on;

IF(SELECT COUNT(*) FROM INSERTED) = 0
    RETURN;


merge into  [dbo].[table1] with (HOLDLOCK) as d
using INSERTED as i 
on (i.[primarykey] = d.[primarykey])
when not matched then 
insert (d.Column1,d.Column2,d.Column3,d.Column4,...)
values (i.Column1,i.Column2,i.Column3,i.Column4,...)

END

Answer 2

ALTER TRIGGER tr_Emp_forInsert
On Emp
For Insert
AS
BEGIN

    Declare @Id int
    select @Id = ID from inserted

    insert into EmpAudit
    values('New employee with ID =  ' + cast (@Id as nvarchar(5))  + ' is added at ' 
    + cast (Getdate () as nvarchar(20)))
end

列名或提供的值与表定义不匹配。

创建触发器时出错：列名或提供的值数与表定义不匹配
