MySql如何对数字格式后的结果进行排序？

Question

我想返回按 tcv SUM 的结果降序排列的结果。如果我删除 FORMAT() 函数，这会很好地工作，但是当我将 FORMAT() 函数添加到 SUM 时，它会按第一位数字的顺序返回结果，而不是查看整个数字。

所以它会在 7,456,234.00 之前返回 87,400.00，因为 8 在 7 之后，这显然不是期望的结果。

SELECT
x.user as user, u.name, 
FORMAT(SUM(IF(x.stage IN ('Closed Won') AND x.close_date BETWEEN '2018-04-01 00:00:00' AND '2018-04-30', x.amount_base, 0)), 2) as tcv, 
FORMAT(SUM(IF(x.stage IN ('Closed Won') AND x.close_date BETWEEN '2018-04-01 00:00:00' AND '2018-04-30', x.mrr_base, 0)), 2) as mrr,
FROM table AS x 
LEFT JOIN users u ON x.owner = u.name WHERE x.resign_new = 'New' AND x.owner IN ("Name 1", "Name 2", "Name 3")  
GROUP BY x.owner   
ORDER BY tcv DESC

我需要适当的格式，因为数字需要使用逗号分隔符进行格式化以提高可读性。

MySQL 错误地返回 ORDER BY 我做错了什么？

Answer 1

sum 函数根据您要聚合的列的数据类型返回小数或 double 。因此，要正确排序，您可以删除排序依据中的格式子句。见下文。

SELECT
x.user as user, u.name, 
FORMAT(SUM(IF(x.stage IN ('Closed Won') AND x.close_date BETWEEN '2018-04-01 00:00:00' AND '2018-04-30', x.amount_base, 0)), 2) as tcv, 
FORMAT(SUM(IF(x.stage IN ('Closed Won') AND x.close_date BETWEEN '2018-04-01 00:00:00' AND '2018-04-30', x.mrr_base, 0)), 2) as mrr,
FROM table AS x 
LEFT JOIN users u ON x.owner = u.name WHERE x.resign_new = 'New' AND x.owner IN ("Name 1", "Name 2", "Name 3")  
GROUP BY x.owner   
ORDER BY (SUM(IF(x.stage IN ('Closed Won') AND x.close_date BETWEEN '2018-04-01 00:00:00' AND '2018-04-30', x.amount_base, 0))) DESC
