我有3个不同的查询显示相同的数据,但是对于不同的日期间隔。我不确定将查询组合在一起以显示所有数据的最佳方法。我对连接或嵌套查询不是很了解,所以我不确定最好的方法。
基本上我想要4列:Associate,30 Days,60 Days和90 Days。
查询1:
SELECT cwd_user.display_name AS 'Associate', sum(worklog.timeworked/3600) AS '30 Days'
FROM worklog, cwd_user,cwd_membership
WHERE worklog.AUTHOR = cwd_user.user_name
and cwd_user.directory_id = cwd_membership.directory_id
and cwd_user.lower_user_name = cwd_membership.lower_child_name
and cwd_membership.membership_type = 'GROUP_USER'
and cwd_membership.lower_parent_name = 'atl_servicedesk_it_agents'
and worklog.STARTDATE BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 30 DAY)
GROUP BY cwd_user. display_name
ORDER BY cwd_user.last_name;
查询2:
SELECT cwd_user.display_name AS 'Associate', sum(worklog.timeworked/3600) AS '60 Days'
FROM worklog, cwd_user,cwd_membership
WHERE worklog.AUTHOR = cwd_user.user_name
and cwd_user.directory_id = cwd_membership.directory_id
and cwd_user.lower_user_name = cwd_membership.lower_child_name
and cwd_membership.membership_type = 'GROUP_USER'
and cwd_membership.lower_parent_name = 'atl_servicedesk_it_agents'
and worklog.STARTDATE BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 60 DAY)
GROUP BY cwd_user. display_name
ORDER BY cwd_user.last_name;
查询3:
SELECT cwd_user.display_name AS 'Associate', sum(worklog.timeworked/3600) AS '90 Days'
FROM worklog, cwd_user,cwd_membership
WHERE worklog.AUTHOR = cwd_user.user_name
and cwd_user.directory_id = cwd_membership.directory_id
and cwd_user.lower_user_name = cwd_membership.lower_child_name
and cwd_membership.membership_type = 'GROUP_USER'
and cwd_membership.lower_parent_name = 'atl_servicedesk_it_agents'
and worklog.STARTDATE BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 90 DAY)
GROUP BY cwd_user. display_name
ORDER BY cwd_user.last_name;
答案 0 :(得分:0)
未经测试...因为没有什么可以测试它...
SELECT u.display_name Associate
, SUM(CASE WHEN w.startdate BETWEEN NOW() AND NOW() + INTERVAL 30 DAY THEN w.timeworked END/3600) '30 Days'
, SUM(CASE WHEN w.startdate BETWEEN NOW() AND NOW() + INTERVAL 60 DAY THEN w.timeworked END/3600) '60 Days'
, SUM(CASE WHEN w.startdate BETWEEN NOW() AND NOW() + INTERVAL 90 DAY THEN w.timeworked END/3600) '90 Days'
FROM worklog w
JOIN cwd_user u
ON u.user_name = w.author
JOIN cwd_membership m
ON m.directory_id = u.directory_id
AND m.lower_child_name = u.lower_user_name
WHERE m.membership_type = 'GROUP_USER'
AND m.lower_parent_name = 'atl_servicedesk_it_agents'
AND w.startdate BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 90 DAY)
GROUP
BY u. display_name
ORDER
BY u.last_name;
