爲什麼SQL Server無法找到新創建的函數？

Question

我不知道爲什麼最近我創建函數，但SQL Server在調用它們時返回錯誤，以防它們被添加到數據庫的函數列表中。

例如以下函數I得到這樣一個錯誤：

declare @cats nvarchar(1000) 
set @cats = 'a|b|c|d|e' 

SELECT dbo.fncSplit(@Cats, '|') 

錯誤：

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

示例函數：

CREATE FUNCTION [dbo].fncSplit 
( 
    @RowData NVARCHAR(MAX), 
    @Delimeter NVARCHAR(MAX) 
) 
RETURNS @RtnValue TABLE 
(
    ID INT IDENTITY(1,1), 
    Data NVARCHAR(MAX) 
) 
AS 
BEGIN 
    DECLARE @Iterator INT 
    SET @Iterator = 1 

    DECLARE @FoundIndex INT 
    SET @FoundIndex = CHARINDEX(@Delimeter,@RowData) 

    WHILE (@FoundIndex>0) 
    BEGIN 
     INSERT INTO @RtnValue (data) 
     SELECT 
      Data = LTRIM(RTRIM(SUBSTRING(@RowData, 1, @FoundIndex - 1))) 

     SET @RowData = SUBSTRING(@RowData, 
       @FoundIndex + DATALENGTH(@Delimeter)/2, 
       LEN(@RowData)) 

     SET @Iterator = @Iterator + 1 
     SET @FoundIndex = CHARINDEX(@Delimeter, @RowData) 
    END 

    INSERT INTO @RtnValue (Data) 
    SELECT Data = LTRIM(RTRIM(@RowData)) 

    RETURN 
END 

任何建議或溶液將高度讚賞。

這是表值函數。語法是

declare @cats nvarchar(1000) 
set @cats = 'a|b|c|d|e' 

SELECT * from dbo.fncSplit(@Cats, '|')
