    SQL 联合查询与XML解析实例详解

    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=3mid=7281PID='+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=3mid=7281PID='+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)
    left join (select * from [10.2.3.39].AspireworkFlow.dbo.RepeaingTable) as h on (h.Keyword='FKXX_New' and h.ProcessID=e.PID or h.Keyword='FKXX' and h.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
