sql - 我将如何舍入这个 sql 查询

Question

 SELECT       name, address1, address2, address3, city, state, zip, faxnum, phonenum, emailaddress, 
  odbcadmin.fn_calDist(- 0.03715491813985, 0.9178158214586024, long * 0.0174532925, lat * 0.0174532925) 
  AS distances
  FROM       dbo.Customer 
  WHERE     (odbcadmin.fn_calDist(- 0.03715491813985, 0.9178158214586024, long * 0.0174532925, lat * 0.0174532925) <= 150)
  ORDER BY distances

所有这些代码所做的是获取距离，然后按升序将它们显示在 microsoft sql 表中，并且它还有一个条件是只显示 150 英里内的距离，但我不知道如何在 sql 中舍入

Answer 1

使用 ROUND(数字,数字)

SELECT       name, address1, address2, address3, city, state, zip, faxnum, phonenum, emailaddress, 
  ROUND(odbcadmin.fn_calDist(- 0.03715491813985, 0.9178158214586024, long * 0.0174532925, lat * 0.0174532925) ,2)
  AS distances
  FROM       dbo.Customer 
  WHERE     (ROUND(odbcadmin.fn_calDist(- 0.03715491813985, 0.9178158214586024, long * 0.0174532925, lat * 0.0174532925),2) <= 150)
  ORDER BY distances`
