Question

我的查询提取了我们系统中contacts总交易0的所有contact_status_c = Client和SELECT contacts.first_name, contacts.last_name, contacts.phone_home, contacts.phone_mobile, contacts.phone_work, contacts.primary_address_street, contacts.primary_address_city, contacts.primary_address_state, contacts.primary_address_postalcode, contacts.primary_address_country, opportunities_cstm.stage_c, contacts_cstm.contact_status_c, SUM(opportunities_cstm.stage_c = 'Pending' OR opportunities_cstm.stage_c = 'AccountActive' OR opportunities_cstm.stage_c = 'Reinstated' OR opportunities_cstm.stage_c = '%Maturity%' OR opportunities_cstm.stage_c = 'Flagged' OR opportunities_cstm.stage_c = 'Stalled') AS deal_count FROM opportunities JOIN opportunities_cstm ON opportunities.id = opportunities_cstm.id_c RIGHT JOIN contacts ON opportunities_cstm.contact_id_c = contacts.id JOIN contacts_cstm ON contacts_cstm.id_c = contacts.id WHERE contacts.deleted = 0 AND opportunities.deleted = 0 AND contacts_cstm.contact_status_c <> 'Lost Client' GROUP BY contacts.id HAVING deal_count = 0 ORDER BY contacts.first_name ASC, contacts.last_name ASC。查询如下：

contact_status_c

它吸引了175个联系人。现在，我正在尝试更新contacts_cstm表中的所有Lost Clients条记录，以反映其中所有175个客户端都列为Client而不是https://stackoverflow.com/questions/8793914/using-a-having-clause-in-an-update-statement。这就是问题所在。

最初，我只是尝试使用基本的Update语句来执行此操作，但由于它太宽泛，它更新了1881条记录而不是175条。因此，我总结说我需要包括分组和拥有。使用以下提供的信息：

UPDATE
    c_1
FROM
    contacts_cstm c_1
    JOIN (
        SELECT
            contacts.first_name,
            contacts.last_name,
            contacts.phone_home,
            contacts.phone_mobile,
            contacts.phone_work,
            contacts.primary_address_street,
            contacts.primary_address_city,
            contacts.primary_address_state,
            contacts.primary_address_postalcode,
            contacts.primary_address_country,
            opportunities_cstm.stage_c,
            contacts_cstm.contact_status_c,
            SUM(opportunities_cstm.stage_c = 'Pending'
            OR opportunities_cstm.stage_c = 'AccountActive'
            OR opportunities_cstm.stage_c = 'Reinstated'
            OR opportunities_cstm.stage_c = '%Maturity%'
            OR opportunities_cstm.stage_c = 'Flagged'
            OR opportunities_cstm.stage_c = 'Stalled') AS deal_count
        FROM
            Contacts_Cstm 
        RIGHT JOIN contacts
            ON opportunities_cstm.contact_id_c = contacts.id
        JOIN opportunities_cstm
            ON opportunities.id = opportunities_cstm.id_c
        JOIN opportunities
            ON opportunities_cstm.id_c = opportunities.id
        WHERE
            contacts.deleted = 0
            AND opportunities.deleted = 0
            AND contacts_cstm.contact_status_c <> 'Lost Client'
        GROUP BY
            contacts.id
        HAVING 
            deal_count = 0
    ) contacts_cstm as c_2
    ON
        c_1.id_c = c_2.id_c
    SET 
        contact_status_c = 'Lost Client'

（这是最有用的）以及我设法撰写此声明的其他几篇论坛帖子和文章：

Error : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM
    contacts_cstm c_1
    JOIN (
        SELECT
            contacts.first_name,
            contacts.las' at line 3

不幸的是，它引发了一个“简单”的语法错误：

Recipe/Ingredients/Ingredient

我已经通过文献和这里的几个帖子进行了广泛的观察，但是我们无法弄清楚这里出了什么问题。我有一种感觉，它与投掷的错误没有任何关系。

绝对赞赏任何和所有帮助。提前谢谢！

我没有在我的系统上安装MySQL因此我无法对其进行测试，但它应该与下面的查询类似。此外，您还没有提供表格结构，因此我假设您有一个id列。

UPDATE contacts_cstm a
JOIN (
    SELECT contacts.first_name,
        contacts.last_name,
        contacts.phone_home,
        contacts.phone_mobile,
        contacts.phone_work,
        contacts.primary_address_street,
        contacts.primary_address_city,
        contacts.primary_address_state,
        contacts.primary_address_postalcode,
        contacts.primary_address_country,
        opportunities_cstm.stage_c,
        contacts_cstm.id_c
        contacts_cstm.contact_status_c,
        SUM(opportunities_cstm.stage_c = 'Pending' OR opportunities_cstm.stage_c = 'AccountActive' OR opportunities_cstm.stage_c = 'Reinstated' OR opportunities_cstm.stage_c = '%Maturity%' OR opportunities_cstm.stage_c = 'Flagged' OR opportunities_cstm.stage_c = 'Stalled') AS deal_count
    FROM opportunities
    JOIN opportunities_cstm ON opportunities.id = opportunities_cstm.id_c
    RIGHT JOIN contacts ON opportunities_cstm.contact_id_c = contacts.id
    JOIN contacts_cstm ON contacts_cstm.id_c = contacts.id
    WHERE contacts.deleted = 0 AND opportunities.deleted = 0 AND contacts_cstm.contact_status_c <> 'Lost Client'
    GROUP BY contacts.id
    HAVING deal_count = 0
) b ON b.id_c = a.id_c
SET a.contact_status_c = 'Lost Client'

加入查询
