选择所有记录中，其中加入比一个月前不到一个月前多，得分X

Question

的从下面的表格，我想选择的记录是：

• 内部已经增加上个月
• 记录但一个多月前加入，并有分数的（不管分）> = 10

我的努力是下面的，但我会错了地方

select id from candidates 
where dateEnrolled >= date_sub(now(), interval 1 month) 
and dateEnrolled <= now() and score >=10; 

我一直在7 and 8。正确的答案应该只包括以下ID 1 2 5 6 7 8 9 10

你能帮忙吗？

"id" "dateEnrolled" "score" 
"1"  "2013-01-01" "12" 
"2"  "2013-02-01" "15" 
"3"  "2013-03-01" "9" 
"4"  "2013-04-01" "8" 
"5"  "2013-05-01" "20" 
"6"  "2013-08-01" "0" 
"7"  "2013-08-12" "10" 
"8"  "2013-08-13" "12" 
"9"  "2013-08-15" "1" 
"10" "2013-08-17" "5" 

Answer 1

试着这么做

select id from candidates where dateEnrolled >= date_sub(now(), interval 1 month) 
     or (dateEnrolled <= now() and score >=10); 

交换你and选择一个or。

where dateEnrolled >= date_sub(now(), interval 1 month)

or (score >=10 and dateEnrolled < date_sub(now(), interval 1 month));
