我的sql数据库中有一个标量值函数.

将此函数导入Entity Framework模型时收到此错误:

Error 6046: Unable to generate function import return type of the store function 'GetContentByIdAndCul'.
The store function will be ignored and the function import will not be generated.   ..\EntityModels.edmx

我的函数tsql是:

ALTER FUNCTION [FRM].[GetContentByIdAndCul] 
(@Id int,@Culture nvarchar(5))
RETURNS nvarchar(max)
AS
BEGIN
declare @Result nvarchar(max)

if @Id is not null
    set @Result='This Content not defined in this Language'

select @Result=Value from CUL.Contents
WHERE ID=@Id AND (CUL.Contents.Culture = LOWER(@Culture) 
            OR CUL.Contents.Culture = LOWER(SUBSTRING(@Culture,1,2)))   
return @Result      
END
