sql-server - 使用逗号分隔符获取浮点值

Question

我是新手Sql server ce。我的表有浮点值。我想用逗号分隔和小数点选择浮点数。像这样

表名table1

 val
 1220333
 222
 36535

我想要这样的结果

val
12,20,333.00
222.00
36,535.00

像印度卢比

我正在使用Sql server ce 3.5

Answer 1

DECLARE @Table1 TABLE 
    (val int)
;

INSERT INTO @Table1
    (val)
VALUES
    (1220333),
    (222),
    (36535)
;
select convert(varchar(50), CAST(val as money), -1) amount from @Table1

select FORMAT(CAST(val AS MONEY),'N','en-in') amount from @Table1

或者

功能

create function to_indian_currency(@n decimal(25,5))
returns varchar(100) as
BEGIN
declare @a varchar(100) = cast(@n as varchar(100))
declare @dec_part varchar(100) = 
(select substring(@a, charindex('.',@a), len(@a)-charindex('.',@a)+1))
declare @int_part varchar(100) = (select left(@a, charindex('.',@a)-1))
declare @f int = cast(@int_part as bigint)%1000
declare @q int = cast(@int_part as bigint)/1000
declare @final varchar(100) = ''
while @q > 0
begin
set @final = cast(@q%100 as varchar) + ',' + @final
set @q = @q/100
end
RETURN @final + cast(@f as varchar) + @dec_part
END

从@Table1 中选择 dbo.to_indian_currency(val)
