出现问题的sql

sql 复制代码 
        SELECT t1.person_id AS personId,
        t1.employee_number AS employeeNumber,
        t1.chinese_name AS chineseName,
        t1.org_name AS orgName,
        t1.job_name AS jobName,
        t1.grade_name AS gradeName,
        t1.dimission_time AS dimissionTime,
        t1.issue_time AS issueTime from person_dimission_info t1 GROUP BY
        t1.person_id HAVING COUNT(1)=1 AND date_sub(now(), interval 30 day)>issue_time

问题处理

首先问题很明显，是因为date_sub函数导致的

修改完了之后还是不行

sql 复制代码 
SELECT t1.person_id       AS personId,
       t1.employee_number AS employeeNumber,
       t1.chinese_name    AS chineseName,
       t1.org_name        AS orgName,
       t1.job_name        AS jobName,
       t1.grade_name      AS gradeName,
       t1.dimission_time  AS dimissionTime,
       t1.issue_time      AS issueTime
from PERSON2.person_dimission_info t1
GROUP BY t1.person_id
HAVING COUNT(1) = 1
   AND add_days(now(), -30) > issue_time

然后就很明显了，这里的group by 分组应该是使用的oracle中的类似的方式，只有出现在group by 的列才可以出现在select之后。然后决定开始写子循环。

sql 复制代码 
SELECT t1.person_id       AS personId
from PERSON2.person_dimission_info t1
GROUP BY t1.person_id
HAVING COUNT(1) = 1 and add_days(now(), -30) > t1.issue_time

然后出现了新的问题，我还以为是因为dm数据库不认having后面参数累加来着，因为之前处理过类似的问题。

sql 复制代码 
SELECT t1.person_id       AS personId
from PERSON2.person_dimission_info t1
GROUP BY t1.person_id
HAVING COUNT(1) = 1 and 1=1

发现，其实他认having后面跟and，只不过我写的这个时间函数不认而已。

那没有办法，不能放在having，就放在where呗，一样的

sql 复制代码 
SELECT t1.person_id       AS personId
from PERSON2.person_dimission_info t1
where    add_days(now(), -30) > t1.issue_time
GROUP BY t1.person_id
HAVING COUNT(1) = 1

最后写好的子循环

实话说我也不知道为啥不能够写=，我就换成了in
