只选择并显示 MySQL 中的重复记录
这个问题很简单,我由于某种原因无法得到正确的结果来只显示重复的记录
This question is pretty simple I for some reason can't get the proper result to display only the duplicate records
Table : Paypal_ipn_orders
id payer_email
1 susan@gmail.com
2 ryan@gmail.com
3 susan@gmail.com
4 steve@gmail.com
5 steve@gmail.com
SELECT id, COUNT( payer_email ) `tot`
FROM paypal_ipn_orders
GROUP BY payer_email
HAVING `tot` >1
样本输出
id tot
1 2
4 2
预期输出
id payer_email
1 susan@gmail.com
3 susan@gmail.com
4 steve@gmail.com
5 steve@gmail.com
我该如何做到这一点?
推荐答案
SELECT id, payer_email
FROM paypal_ipn_orders
WHERE payer_email IN (
SELECT payer_email
FROM paypal_ipn_orders
GROUP BY payer_email
HAVING COUNT(id) > 1
)
