如何在SQL Server 2005中没有落后零的情况下四舍五入？

？

    select round(100.5555, 2)

...产量100.5500。如何摆脱零？

Answer 1

try这个

select CAST(round(100.5555, 2) AS DECIMAL(8,2))

Answer 2

SELECT CAST(ROUND(100.5555, 2) AS FLOAT)

，这听起来像显示逻辑，因此，我怀疑您最好在UI中而不是DB中这样做。 Declare @d Decimal（8,2）可以为您提供帮助。

SELECT replace(rtrim(replace(convert(varchar, F_Percent),'0',' ')),' ','0') 'Original Test Data',
                CASE 
                    WHEN replace(rtrim(replace(convert(varchar, F_Percent),'0',' ')),' ','0') IS NULL OR replace(rtrim(replace(convert(varchar, F_Percent),'0',' ')),' ','0') ='' 
                    OR replace(rtrim(replace(convert(varchar, F_Percent),'0',' ')),' ','0') ='0.'
                        THEN　'0'
                    WHEN LEN(replace(rtrim(replace(convert(varchar, F_Percent),'0',' ')),' ','0')) =PATINDEX('%.%',replace(rtrim(replace(convert(varchar, F_Percent),'0',' ')),' ','0') )
                        THEN SUBSTRING(replace(rtrim(replace(convert(varchar, F_Percent),'0',' ')),' ','0'),0,LEN(replace(rtrim(replace(convert(varchar, F_Percent),'0',' ')),' ','0')))
                    ELSE replace(rtrim(replace(convert(varchar, F_Percent),'0',' ')),' ','0')               
                END N'remove decimals',
                PATINDEX('%.%',replace(rtrim(replace(convert(varchar, F_Percent),'0',' ')),' ','0') ) 'If Decimal Exists'
