Hi,

I have the following user defined functions:

USE [AES_LWM]
GO
/****** Object:  UserDefinedFunction [TRANSACTIONS].[cfn_GetDateByLanguage]    Script Date: 12/07/2015 15:21:05 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO


ALTER FUNCTION [TRANSACTIONS].[cfn_GetDateByLanguage]
(
    @Date date,
    @Language varchar(50)
)
RETURNS nvarchar(50)
AS
BEGIN
    DECLARE @Return_Value nvarchar(50)
    
    IF MONTH(@Date) = 1
     BEGIN
        SET @Return_Value = CASE WHEN @Language = 'CN' THEN '一月' 
                                 WHEN @Language = 'MA' THEN 'Jan'

    IF MONTH(@Date) = 12
     BEGIN
        SET @Return_Value = CASE WHEN @Language = 'CN' THEN '十二月' 
                                 WHEN @Language = 'MA' THEN 'Dis'
                                 ELSE 'Dec' END        
     END
     
    RETURN @Return_Value
END

I tried to SELECT TRANSACTIONS.cfn_GetDateByLanguage(GETDATE(), 'CN') but it return ??? and not the chinese value.

How can I do?
