Question

我需要帮助调整下面的proc，以便能够在从服务表进行搜索时从组织表中返回结果。组织可以在以organization_id键入的服务表中列出多个服务。一个组织，许多服务。当前的proc用于搜索组织并返回该行，如果所有字段都为空，则返回所有组织。我想要更改它，以便我仍然可以维护它，但如果搜索服务，它会返回组织。

SELECT
    organization_id,
    organization_nm,
    contact_nm,
    phone_nr,
    email_ad,
    last_upd_dt,
    update_frequency_cd
FROM ORGANIZATION
WHERE
    organization_id = CASE 
        WHEN @organization_id = 0 THEN organization_id 
        WHEN @organization_id IS NULL THEN organization_id 
        ELSE @organization_id END
    AND organization_nm LIKE CASE 
        WHEN @organization_nm IS NULL THEN organization_nm 
        ELSE '%' + @organization_nm + '%' END
    AND update_frequency_cd = CASE 
        WHEN @update_frequency_cd = 'x' THEN update_frequency_cd 
        ELSE @update_frequency_cd END
    AND operator_id = CASE 
        WHEN @operator_id = 0 THEN operator_id 
        WHEN @operator_id IS NULL THEN operator_id 
        ELSE @operator_id END
ORDER BY organization_nm

我做了这个内部联接，它让我得到了我想要的结果，但是我对如何将它融入过程感到茫然。我一直在尝试很多方法让它发挥作用，但不想用这些尝试来解决我的问题。任何使这两件作品合身的帮助都会非常感激，或者如果我能够通过适当/更简单的方式学习这项工作。

这是我所做的内部联接，它可以让我在搜索服务时找到我想要的结果。

SELECT 
    org.organization_id,
    org.organization_nm,
    org.contact_nm,
    org.phone_nr,
    org.email_ad,
    org.last_upd_dt,
    org.update_frequency_cd,
    service_nm
FROM dbo.ORGANIZATION AS Org
INNER JOIN 
(
SELECT organization_id AS orgId, service_nm
FROM dbo.RECYCLE_SERVICE
WHERE service_nm = 'my service'
) AS serv
ON  Org.organization_id = serv.orgId

尝试：

SELECT
    org.organization_id,
    org.organization_nm,
    org.contact_nm,
    org.phone_nr,
    org.email_ad,
    org.last_upd_dt,
    org.update_frequency_cd,
    service_nm
FROM dbo.ORGANIZATION AS Org
INNER JOIN 
(
SELECT organization_id AS orgId, service_nm
FROM dbo.RECYCLE_SERVICE
WHERE service_nm = 'my service'
) AS serv
ON  Org.organization_id = serv.orgId 
WHERE
    organization_id = CASE 
        WHEN @organization_id = 0 THEN organization_id 
        WHEN @organization_id IS NULL THEN organization_id 
        ELSE @organization_id END
    AND organization_nm LIKE CASE 
        WHEN @organization_nm IS NULL THEN organization_nm 
        ELSE '%' + @organization_nm + '%' END
    AND update_frequency_cd = CASE 
        WHEN @update_frequency_cd = 'x' THEN update_frequency_cd 
        ELSE @update_frequency_cd END
    AND operator_id = CASE 
        WHEN @operator_id = 0 THEN operator_id 
        WHEN @operator_id IS NULL THEN operator_id 
        ELSE @operator_id END
ORDER BY organization_nm

根据表B中的值从表A中获取不同的行
