找不到列“dbo"或用户定义的函数或聚合“dbo.FN_Split"，或者名称不明确 [英] Cannot find either column “dbo” or the user-defined function or aggregate “dbo.FN_Split”, or the name is ambiguous

问题描述

我有以下功能可以接受 CSV &分隔符分裂它

I have following function which accepts the CSV & delimeter & splits it

ALTER FUNCTION [dbo].[FN_Split] (@String varchar(max), @Delimiter char(1))      
returns @temptable TABLE (orderId int,items varchar(max))        
as        
begin        
   declare @idx int   
   declare @i int=0     
   declare @slice varchar(8000)        
   declare @orderId int = 0 --<added a counter

    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(orderId, Items) values(@orderId, @slice)        
       set @orderId = @orderId+1 --<increment the counter

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

&像这样使用上述函数的存储过程 &将结果插入数据库:

& the stored procedure like this which uses the above function & inserts the result into the database:

ALTER PROCEDURE dbo.StoredProcedure3
(
 --@tableName nvarchar(max),
 @p_SourceText nvarchar(max),
 @p_Delimeter nvarchar(100)=','
)

AS
BEGIN
DECLARE @sql nvarchar(max)
--select * from fn_ParseText2Table(@p_SourceText, @p_Delimeter)
--insert into Person values (@sql)
declare @i int=0
DECLARE @max int=3

while @i<=@max
begin
if @i=0
begin
set @sql='insert into Person values( select items from'+dbo.FN_Split(@p_SourceText,  
 @p_Delimeter)+ 'as where orderId ='+0+')'
end

 else
  begin
   if @i=(@max-1)
    begin
 set @sql=@sql+'UNION select items from'+ dbo.FN_Split(@p_SourceText,
                  @p_Delimeter)+' where orderId ='+@i+')'
    end
 else
  begin
   set @sql=@sql+'UNION select items from'+ dbo.FN_Split(@p_SourceText,        
                 @p_Delimeter)+ 'where orderId ='+@i+') UNION'
      end
   end
   set @i=@i+1
end
END 

但在执行程序后，我收到以下错误:找不到列dbo"或用户定义的函数或聚合dbo.FN_Split"，或者名称不明确.没有受影响的行.(返回 0 行)

But After Executing the Procedure I get The Following error: Cannot find either column "dbo" or the user-defined function or aggregate "dbo.FN_Split", or the name is ambiguous. No rows affected. (0 row(s) returned)

请帮助摆脱它...

推荐答案

首先，确保您确实在正确的数据库中运行了创建脚本.

First, make sure you did run the create script in the correct database.

其次，正如@astander 开始提到的，您使用的函数结果不正确.

Second, as @astander started mentioning, you are using the function results incorrectly.

您的函数返回一个表，而不是一个值.您需要将函数作为 sql 语句的一部分执行，而不是在构建临时查询期间执行.例如，这段代码:

Your function returns a table, not a value. You'll need to execute the function as part of your sql statements, not during your build of ad hoc queries. For example, this code:

 set @sql=@sql+'UNION select items from'+ dbo.FN_Split(@p_SourceText,
                  @p_Delimeter)+' where orderId ='+@i+')'

会变成:

set @sql = @sql+'UNION select items from dbo.FN_Split(' + @p_SourceText +', ' +
                  @p_Delimeter + ') where orderId =' + @i + ')'

在您当前引用该函数的任何地方进行类似的更改.

Make similar changes everywhere you are currently referencing the function.
