找不到列“dbo”或用户定义函数或聚合“dbo.Splitfn”，或者名称不明确

我使用了以下分割函数：

CREATE FUNCTION dbo.Splitfn(@String varchar(8000), @Delimiter char(1))       
returns @temptable TABLE (items varchar(8000))       
 as       
begin       
declare @idx int       
declare @slice varchar(8000)       
  
select @idx = 1       
    if len(@String)<1 or @String is null  return       
  
while @idx!= 0       
begin       
    set @idx = charindex(@Delimiter,@String)       
    if @idx!=0       
        set @slice = left(@String,@idx - 1)       
    else       
        set @slice = @String       
      
    if(len(@slice)>0)  
        insert into @temptable(Items) values(@slice)       

    set @String = right(@String,len(@String) - @idx)       
    if len(@String) = 0 break       
end   
return      

end  

我在查询中使用了这个函数并且它被执行了

ALTER PROCEDURE [dbo].[Employees_Delete] 
-- Add the parameters for the stored procedure here
@Id varchar(50)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

-- Insert statements for procedure here

 if exists( select Emp_Id from Employee where Emp_Id=dbo.Splitfn(@Id,','))
begin
    update Employee set Is_Deleted=1 where Emp_Id=dbo.Splitfn(@Id,',')
    select 'deleted' as message
end 
END

但是当我执行存储过程时给出的值是 (1,2) 我收到错误

Cannot find either column "dbo" or the user-defined 
function or aggregate "dbo.Splitfn", or the name is ambiguous.

我检查了我的表值函数，函数“splitfn”在那里，但我不知道出了什么问题？有什么建议..

它是一个表值函数，但您将其用作标量函数。

Try:

where Emp_Id IN (SELECT i.items FROM dbo.Splitfn(@Id,',') AS i)

但是...还要考虑将您的函数更改为内联 TVF，因为它会表现得更好。
