我的查询尝试，我不确定这是否是正确的尝试，如果您独立运行每个查询，结果似乎完全没有。
SELECT
sum(przychody.netto) as last_month,
sum(Query1.netto) AS this_month
FROM
przychody,
(SELECT
*
FROM
przychody
WHERE
przychody.sprzedano >= Last_Day(CURRENT_DATE()) + INTERVAL 1 DAY - INTERVAL 2 MONTH AND
przychody.sprzedano < Last_Day(CURRENT_DATE()) + INTERVAL 1 DAY - INTERVAL 1 MONTH
) Query1
WHERE
przychody.sprzedano >= Last_Day(CURRENT_DATE()) + INTERVAL 1 DAY - INTERVAL 1 MONTH
SQLFiddle playground：http://sqlfiddle.com/#!9/e18a49/1
首选输出
Last_month |这个月 SUM（）| SUM（）
答案 0 :(得分：1)
您可以使用case中的sum()
SELECT
SUM( CASE WHEN sprzedano >= DATE_FORMAT(NOW() ,'%Y-%m-01') AND sprzedano <= LAST_DAY(NOW()) THEN netto ELSE 0 END) this_month,
SUM( CASE WHEN sprzedano >= DATE_FORMAT(NOW() - INTERVAL 1 MONTH ,'%Y-%m-01') AND sprzedano <= LAST_DAY(NOW() - INTERVAL 1 MONTH) THEN netto ELSE 0 END) last_month
FROM `przychody`
