Question

嗨我使用以下来将数字转换为单词（字符串）在sql server标量函数中但没有获得所需的结果。

    GO
/****** Object:  UserDefinedFunction [dbo].[fNumToWords]    Script Date: 03/02/2015 15:44:51 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER function [dbo].[fNumToWords]
(@decNumber decimal(12, 2)) 
returns varchar(300) 
As 
Begin 
Declare 
 @strnum varchar(100), 
 @strCents varchar(100), 
 @strWords varchar(300), 
 @intIndex integer 


Select @strnum = Cast(@decNumber as varchar(100)) 
Select @intIndex = CharIndex('.', @strnum) 
select @strCents = '' 

if(@decNumber>999999999.99) 
BEGIN  
 RETURN '' 
END 

If @intIndex > 0  
begin 
 Select @strCents = dbo.fConvertTens(Right(@strnum, Len(@strnum) - @intIndex)) 
 Select @strnum = SubString(@strnum, 1, Len(@strnum) - 3) 
 If Len(@strCents) > 0 Select @strCents = @strCents + ' Cents' 
end 

declare @trail_zeros  varchar(3) 
declare @strthousands varchar(3) 
declare @strMillions varchar(3) 

set @trail_zeros = '000' 

if len(@strnum) <= 3 
begin 
 select @strWords = dbo.fConvertHundreds(left(@trail_zeros,3-len(right(@strnum,3)))+ right(@strnum,3)) 
end  
if len(@strnum) >= 4 and len(@strnum) <=6 
begin 
 select @strthousands = left(@trail_zeros,3 - len(left(right(@strnum,6),len(@strnum)-3))) + left(right(@strnum,6),len(@strnum)-3) 
 select @strWords = dbo.fConvertHundreds(@strthousands) + ' Thousand ' + dbo.fConvertHundreds(left(@trail_zeros,3-len(right(@strnum,3)))+ right(@strnum,3)) 
end 
if len(@strnum) >= 7 and len(@strnum) <=9 
begin 
 select @strMillions = left(@trail_zeros,3-len(left(@strnum,len(@strnum)-6))) + left(@strnum,len(@strnum)-6) 
 select @strthousands = left(right(@strnum,6),3) 
 select @strWords = dbo.fConvertHundreds(@strMillions) + ' Lakhs ' + dbo.fConvertHundreds(@strthousands) + ' Thousand ' + dbo.fConvertHundreds(left(@trail_zeros,3-len(right(@strnum,3)))+ right(@strnum,3)) 
end 

if @strCents <> '' 
 select @strWords = @strWords + ' and ' + @strCents + ' Only' 
else 
 select @strWords = @strWords + ' Only' 

return  @strWords 

end

它将显示输出

只有六十六万四千六百五十

但我想要六十六万六十四数千五百五十 fconverthunreds ....

请检查此链接。

select dbo.[NumberToWords](664650)  --RUN THIS AFTER ABOVE LINK'S FUNCTION EXECUTE

而且，我在下面的链接中更改了一部分。
