我有表名用户。
id name date cdate c a b
1 rz 42121221 42121221 0 1 0
2 an 12122111 42121221 0 0 1
3 cb 22121221 42121221 1 1 1
4 ss 3321221 42121221 1 0 0
我有两个选择两个日期之间的值,然后我必须使用此语句找到计数。
SELECT COALESCE(SUM(IF(c=1 AND a=0 AND b=1 , 1, 0)),0) AS ACTIVE WHERE DATE BETWEEN 'DATE 1' AND 'DATE 2',COALESCE(SUM(IF(c=0 AND a=0 AND b=1 , 1, 0)),0) AS INC WHERE cdate BETWEEN 'DATE 1' AND 'DATE 2' FROM users
此查询无效
答案 0 :(得分:1)
使用
select COALESCE(SUM(IF(c=1 AND a=0 AND b=1 , 1, 0)),0) AS ACTIVE from users where date between 'date1' and date '2'
