当我尝试在SQL Server 2005中执行以下代码时,我收到错误

列名称DistanceFromAddress无效

码:

select 
    SQRT(POWER(cast(Program_Latitude as float) - cast('41.5126237' as float), 2) +   
    POWER(cast(Program_Longitude as float) - cast('-81.6516411' as float), 2)) * 62.1371192 AS DistanceFromAddress 
from 
    tblProgram 
where 
    DistanceFromAddress < 2

我正在使用select语句正确获取值,但是当我尝试检查条件时,where DistanceFromAddress < 2我收到错误.

我该如何解决这个问题？
