sql-server - 如何在sql中获得小数点后2位？

Question

我在选择列中格式化数字时遇到问题。我使用了 FORMAT，但它不起作用。 这是我的专栏:

sum(cast(datediff(second, IEC.CREATE_DATE, IEC.STATUS_DATE) as float) / 60) TotalSentMinutes    

我用过这个:

FORMAT(sum(cast(datediff(second, IEC.CREATE_DATE, IEC.STATUS_DATE) as float) / 60),2) TotalSentMinutes  

错误:

'format' is not a recognized built-in function name.

我怎样才能格式化这个计算？

Answer 1

试试这个 -

DECLARE @i FLOAT = 6.677756

SELECT 
      ROUND(@i, 2)
    , FORMAT(@i, 'N2')
    , CAST(@i AS DECIMAL(18,2))
    , SUBSTRING(PARSENAME(CAST(@i AS VARCHAR(10)), 1), PATINDEX('%.%', CAST(@i AS VARCHAR(10))) - 1, 2)
    , FLOOR((@i - FLOOR(@i)) * 100)

输出:

----------------------
6,68
6.68
6.68
67
67
