如何为 sql 子查询排除计数为 returns 0 的行

Question

我正在使用 System Center Data 处理更新合规性报告。我有我想要的查询，但我无法删除更新失败计数为 0 的行，或者我的 Required/Deployed 更新。

我玩过 HAVING，但只得到 return NULLS，但仍然无法排除它们。

select distinct
rs.name0 as 'Computer Name',
rs.description0 AS 'Description',
os.Caption0 as 'Operating System',
case 
      when CS.ClientActiveStatus='1' then 'Active' 
      when CS.ClientActiveStatus='0' then 'Inactive'
end
      as 'Client Active Status',

--Last Hardware Scan
convert(varchar(26), ws.lasthwscan, 100) as 'Last Hardware Scan',

--Last Software Scan (Convert to EST)
convert(varchar(26), (dateadd(hour, -4, uss.LastScanTime)), 100) as 'Last Software Scan',

--Required/Deployed Updates
(select count(ucs.ResourceID)
from v_Update_ComplianceStatus ucs
    join v_updateinfo ui on ui.ci_id=ucs.ci_id
    join V_CITargetedMachines ctm on ctm.ci_id=ucs.ci_id and ctm.ResourceID = ucs.ResourceID
where ucs.resourceid=rs.ResourceID and ucs.Status='2' and ui.LocaleID='9' and ui.IsDeployed='1' and ui.IsSuperseded='0'
) as 'Required/Deployed Updates',

--Failed Updates
(select count(ucs.ResourceID)
from v_UpdateComplianceStatus ucs
    join v_UpdateInfo ui on ucs.ci_id=ui.ci_id and ucs.Status='2'  and ui.LocaleID='9' and ui.IsDeployed='1' and ui.IsSuperseded='0' and ucs.LastEnforcementMessageID In (6,11,14)
    join v_StateNames sn on ucs.LastEnforcementMessageID = sn.StateID and sn.TopicType=402
where ucs.resourceid=rs.ResourceID
) as 'Failed Updates',

--Reboot Check
(select iif(sum(iif(ucs.LastEnforcementMessageID='9',1,0)) > 0,'Yes','No')
from v_UpdateComplianceStatus ucs
where ucs.resourceid=rs.ResourceID
) as 'Reboot Required'

from v_R_System rs
    join v_GS_OPERATING_SYSTEM os on rs.ResourceID=os.ResourceID
    join v_FullCollectionMembership fcm on rs.ResourceID=fcm.ResourceID
    join v_Collection col on fcm.CollectionID=col.CollectionID
    Join v_CH_ClientSummary CS on rs.ResourceId=CS.ResourceID
    join v_GS_WORKSTATION_STATUS ws on rs.ResourceID=ws.ResourceID
    join v_UpdateScanStatus uss on rs.ResourceID=uss.ResourceID

where 'Required/Deployed Updates' > '0' and 'Failed Updates' > '0'
order by rs.Name0 asc

如果 Required/Deployed 更新或失败更新计数为 0，我希望排除在外。

您不能在 WHERE 子句中使用别名。

您可以将另一个 SELECT 包裹在您的周围，并将条件应用于那里的别名表达式。

SELECT ...
       FROM (SELECT ...,
                    (SELECT count(...)
                            FROM v_update_compliancestatus ucs
                            ...) "Required/Deployed Updates"
                    (SELECT count(...)
                            FROM v_update_compliancestatus ucs
                            ...) "Failed Updates",
                    FROM ...
                    WHERE ...) x
       WHERE "Required/Deployed Updates" > 0
             AND "Failed Updates" > 0;

或者您可以简单地重复表达式，在您的情况下是子选择。

SELECT ...
      (SELECT count(...)
              FROM v_update_compliancestatus ucs
              ...) "Required/Deployed Updates",
      (SELECT count(...)
              FROM v_update_compliancestatus ucs
              ...) "Failed Updates"
      ...
      FROM ...
      WHERE ...
            AND (SELECT count(...)
                        FROM v_update_compliancestatus ucs
                        ...) > 0
            AND (SELECT count(...)
                        FROM v_update_compliancestatus ucs
                        ...) > 0
      ...

在你的情况下，因为你想检查 table 的行数不为零，即如果存在一行，你也可以在 [=13] 中使用 EXISTS =] 子句，这可能会加快速度。

SELECT ...
      (SELECT count(...)
              FROM v_update_compliancestatus ucs
              ...) "Required/Deployed Updates",
      (SELECT count(...)
              FROM v_update_compliancestatus ucs
              ...) "Failed Updates"
      ...
      FROM ...
      WHERE ...
            AND EXISTS (SELECT *
                               FROM v_update_compliancestatus ucs
                               ...)
            AND EXISTS (SELECT *
                               FROM 
                               v_update_compliancestatus ucs)
      ...

另请注意，您不需要将数字文字用单引号引起来 ('。也不要将别名用单引号引起来，使用双引号 (") 如果您想要或需要引用别名。在 SQL 服务器中，您还可以使用方括号，如 [alias].
