我很难从表格中选择当年未修改的行。这是我放弃的查询示例:
SELECT * FROM test_cars INNER JOIN
(SELECT car as c, type as t FROM test_cars
WHERE YEAR(modified_on)='2016' GROUP BY c,t) as tbl
ON tbl.c!=car AND tbl.t!=type
WHERE value !=''
GROUP BY car,type
最佳答案
SELECT car, type
FROM test_cars
GROUP BY car, type
HAVING sum(YEAR(modified_on) = 2016) = 0
关于MYSQL::从没有最新行的表中选择行，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36343754/
