Question

是否可以在同一声明中分组并排序？以下语句以随机顺序输出月份。它会生成正确的数字等，但我想将这些月份显示为1月，2月，3月，4月等顺序

SELECT coalesce(date_format(TRANSACTION_DATE, '%M'), 'Grand Total') AS MONTH,
ROUND(SUM(SALES_AMOUNT),2) TOTAL, SUM(QUANTITY) AS TOTAL_QUANTITY
FROM SALES
WHERE YEAR(TRANSACTION_DATE) = 2018
GROUP BY month WITH ROLLUP;

April       30826.68    476
August      39703.85    619
December    36986.16    515

Answer 1

是否可以在同一声明中分组并排序？是的，这可能只是你需要解决它。

如果您可以从此查询中删除汇总，则可以执行以下排序：

SELECT coalesce(date_format(TRANSACTION_DATE, '%M'), 'Grand Total') AS MONTH, ROUND(SUM(SALES_AMOUNT),2) TOTAL, SUM(QUANTITY) AS TOTAL_QUANTITY FROM SALES WHERE YEAR(TRANSACTION_DATE) = 2018 GROUP BY month order by month(TRANSACTION_DATE) asc;

Answer 2

This should order the months in the expected order:

SELECT coalesce(date_format(TRANSACTION_DATE, '%M'), 'Grand Total') AS MONTH,
ROUND(SUM(SALES_AMOUNT),2) TOTAL, SUM(QUANTITY) AS TOTAL_QUANTITY
FROM SALES
WHERE YEAR(TRANSACTION_DATE) = 2018
GROUP BY month WITH ROLLUP
ORDER BY date_format(TRANSACTION_DATE, '%m');

Notice the lower case m in the order by. That's for the numerical representation of the month.
