使用LIKE搜索GROUP_CONCAT

Question

我有一个SQL查询,它使用GROUP_CONCAT来使所有人都附加到某个订单.有没有办法在GROUP_CONCAT字段内搜索？

SELECT orders.orderID, 
GROUP_CONCAT(contacts.firstName, " ", contacts.lastName) AS attachedContacts
FROM (orders)
JOIN contacts ON orders.contactID=contacts.contactID
GROUP BY orders.orderID
ORDER BY orders.orderID DESC

我想添加类似的内容WHERE attachedContacts LIKE '%Eric%',仅列出附加了"Eric"的订单,但仍然包含查询中的所有其他联系人.

查询返回如下数据:

orderID atachedContacts
01      Eric Siegel, John Smith
02      Jason Jackson, Bill O'Neil
03      Eric Siegel, Jason Jackson, Neil O'Ryan

我希望查询返回行01和03,因为'Eric'在联系人列表中.

我怎样才能做到这一点？

试试这个:

SELECT orders.orderID, 
GROUP_CONCAT(contacts.firstName, " ", contacts.lastName) AS attachedContacts
FROM orders
JOIN contacts ON orders.contactID=contacts.contactID
GROUP BY orders.orderID DESC
HAVING attachedContacts LIKE '%Eric%'
