SQL 联合查询与XML解析实例

          这里举例说明如何实现该功能:

(select a.EBILLNO,
a.EMPNAME,
a.APPLYDATE,
b.HS_NAME,
replace(replace(a.SUMMARY,char(10), ''),char(13),'') as SUMMARY,
cast(c.XmlData as XML).value('(/List/item/No/text())[1]','NVARCHAR(300)') as No,
cast(c.XmlData as XML).value('(/List/item/zje/text())[1]','NVARCHAR(300)') as zje,
cast(c.XmlData as XML).value('(/List/item/yfje/text())[1]','NVARCHAR(300)') as yfje,
cast(c.XMLData as XML).value('(/List/item/bcje/text())[1]','NVARCHAR(300)') as bcje,
cast(c.XMLData as XML).value('(/List/item/URL/text())[1]','NVARCHAR(300)') as URL,
cast(c.XMLData as XML).value('(/List/item/Remark/text())[1]','NVARCHAR(300)') as BZ,
cast(p.XMLData as XML).value('(/NewDataSet/Table1/UserName/text())[1]','NVARCHAR(500)') as SKRXM,
('http://……?sid=3&mid=7281&PID='+a.PID) as bxdljdz
from Ex_Bill as a 
left join Ex_System_Cfg as b on(a.BILLSYSTEMID=b.HS_ID and a.DATASYSTEMID=b.SYSTEM_NAME)
left join (select * from [10.2.3.39].AspireworkFlow.dbo.RepeaingTable) as c on (c.Keyword='URL' and c.ProcessID=a.PID)
left join (select * from [10.2.3.39].AspireworkFlow.dbo.RepeaingTable) as d on (d.Keyword='FKXX_New' and d.ProcessID=a.PID or d.Keyword='FKXX' and d.ProcessID=a.PID)
left join (select * from EX_BillExtension) as p on a.BILLNO=p.BILL_NO

where applyempid='zhongxun' and a.EBILLNO is not null
and status>5 and status not in(200,100,7000)
and a.APPLYDATE>'2011-01-01'
and a.HT='是'
and cast(d.XMLData as XML).value('(/List/item/SKRXM/text())[1]','NVARCHAR(300)') is null) 
union
(select e.EBILLNO,
e.EMPNAME,
e.APPLYDATE,
f.HS_NAME,
replace(replace(e.SUMMARY,char(10), ''),char(13),'') as SUMMARY,
cast(g.XmlData as XML).value('(/List/item/No/text())[1]','NVARCHAR(300)') as No,
cast(g.XmlData as XML).value('(/List/item/zje/text())[1]','NVARCHAR(300)') as zje,
cast(g.XmlData as XML).value('(/List/item/yfje/text())[1]','NVARCHAR(300)') as yfje,
cast(g.XMLData as XML).value('(/List/item/bcje/text())[1]','NVARCHAR(300)') as bcje,
cast(g.XMLData as XML).value('(/List/item/URL/text())[1]','NVARCHAR(300)') as URL,
cast(g.XMLData as XML).value('(/List/item/Remark/text())[1]','NVARCHAR(300)') as BZ,
cast(h.XMLData as XML).value('(/List/item/SKRXM/text())[1]','NVARCHAR(300)') as SKRXM,
('http://……?sid=3&mid=7281&PID='+e.PID) as bxdljdz
from Ex_Bill as e 
left join Ex_System_Cfg as f on(e.BILLSYSTEMID=f.HS_ID and e.DATASYSTEMID=f.SYSTEM_NAME)
left join (select * from [10.2.3.39].AspireworkFlow.dbo.RepeaingTable) as g on (g.Keyword='URL' and g.ProcessID=e.PID)

where applyempid='zhongxun' and e.EBILLNO is not null
and status>5 and status not in(200,100,7000)
and e.APPLYDATE>'2011-01-01'
and e.HT='是'
and cast(h.XMLData as XML).value('(/List/item/SKRXM/text())[1]','NVARCHAR(300)') is not null)

在写SQL的时候,难点不在于SQL本身,而在于逻辑上,当写出这个SQL以后,发现逻辑也没有那么难了。

就是采用Union把两组都查询出来的表放到一个里面

《魔兽世界》大逃杀!60人新游玩模式《强袭风暴》3月21日上线

暴雪近日发布了《魔兽世界》10.2.6 更新内容,新游玩模式《强袭风暴》即将于3月21 日在亚服上线,届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。

艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕,并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时,他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中,玩家将会进入一个全新的海盗主题大逃杀式限时活动,其中包含极高的风险和史诗级的奖励。

《强袭风暴》不是普通的战场,作为一个独立于主游戏之外的活动,玩家可以用大逃杀的风格来体验《魔兽世界》,不分职业、不分装备(除了你在赛局中捡到的),光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式,玩家在加入海盗主题的预赛大厅区域前,可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹,《巨龙崛起》和《魔兽世界:巫妖王之怒 经典版》的玩家都可以获得奖励。
