查询七天之内所有生日的客户

这里并没有考虑跨年的问题（跨年问题正在解决中）

SELECT
sysctr.csr_birthday AS '生日',
usr.user_title AS '登录名',
sysctr.csr_name AS '姓名' 
FROM
user_info usr
JOIN sys_customer sysctr ON usr.pid = sysctr.user_pid
JOIN sys_org org ON sysctr.org_pid = org.pid 
WHERE
org.org_code LIKE '%0' 
AND DATE_FORMAT( sysctr.csr_birthday, '%m-%d' ) > DATE_FORMAT( now(), '%m-%d' ) 
AND DATE_FORMAT( sysctr.csr_birthday, '%m-%d' ) <= DATE_FORMAT(date_add( now(), INTERVAL 54	DAY ),'%m-%d')
