Question

我正在使用DB Browser for DBite，（版本3.10.0，Qt版本5.7.1，SQLCipher版本3.15.2），我有一个列，我想先用最高值排序。我用过：

SELECT first_name, last_name, Totalclaims
FROM workingdata
ORDER BY Totalclaims Desc;

问题是我的查询$993.00被视为大于$9920.00。显然，过滤器无法正确识别小数位。任何建议如何解决这个问题？

Answer 1

清理Totalclaims列，这应该为您订购。

   SELECT first_name, last_name, cast(replace(Totalclaims,'$', '') as SIGNED) as TotalClaims_Clean
    FROM workingdata
    ORDER BY Totalclaims_Clean Desc;

Answer 2

– tonypdmtr wrote: Try with ORDER BY cast(replace(Totalclaims,'$','') as float) Desc;

It worked like a charm.

Answer 3

如果您总是有两位小数，则先按Totalclaims的长度排序，然后再按Totalclaims排序。

编辑：

SELECT first_name, last_name, Totalclaims
FROM workingdata
ORDER BY length(Totalclaims) desc, Totalclaims Desc;

在SQL浏览器的SQL浏览器中按Desc和Asc排序
