编程之家 jb51.cc 有时候在编写存储过程当中，比如一个插入或者修改之类的操作，要传入大量的参数，而且还牵涉到多个主外表关系，现在有一种比较便利的方法可行，就是把要插入的数据以xml的形式，传入到存储过程中。
| 以下为引用的内容： declare @xml varchar(8000) declare @idoc int declare @DeviceMode varchar(20) declare @EquipAttribute varchar(20) declare @Printerstyle varchar(20) declare @Head varchar(20) declare @Code varchar(20) declare @Amount varchar(20) declare @Softedition varchar(20) declare @i int --xml中是一个入库表【CSM_B_DeviceRuKu 】和入库明细表【CSM_B_DeviceRuKu_MX 】 set @xml='<?xml version=''1.0'' encoding=''GB2312''?> <CSM_B_DeviceRuKu BillCode=''BA1059'' EquipAttribute=''0'' Remark=''哈哈'' EnterDate=''2009-10-13'' Person=''1'' Unit=''1'' IsValid=''0'' Devicetotal=''类型：PCI WKT2开票卡，数量：100；类型：32K大容量IC卡，数量：100；''> <CSM_B_DeviceRuKu_MX DeviceMode=''0'' EquipAttribute=''PCI WKT2开票卡'' Printerstyle='''' Softedition='''' Head='''' Code=''12313111111111'' Amount=''100'' /> <CSM_B_DeviceRuKu_MX DeviceMode=''1'' EquipAttribute=''32K大容量IC卡'' Printerstyle='''' Softedition='''' Head='''' Code=''43351212333333'' Amount=''100'' /> <CSM_B_DeviceRuKu_MX DeviceMode=''0'' EquipAttribute=''PCI WKT2开票卡'' Printerstyle='''' Softedition='''' Head='''' Code=''12313111111111'' Amount=''100'' /> <CSM_B_DeviceRuKu_MX DeviceMode=''1'' EquipAttribute=''32K大容量IC卡'' Printerstyle='''' Softedition='''' Head='''' Code=''43351212333333'' Amount=''100'' /> </CSM_B_DeviceRuKu>' --通过存储过程sp_xml_preparedocument来解析xml EXEC sp_xml_preparedocument @idoc output,@xml --读取xml里面的数据【获取CSM_B_DeviceRuKu的数据】 SELECT EquipAttribute,Person,EnterDate,BillCode,Remark,Unit,IsValid,Devicetotal FROM OpenXML(@idoc,'/CSM_B_DeviceRuKu') WITH CSM_B_DeviceRuKu -- 【获取CSM_B_DeviceRuKu_MX的所有数据】 SELECT DeviceMode,EquipAttribute,Printerstyle,Softedition,Head,Code,Amount FROM OpenXML(@idoc,'/CSM_B_DeviceRuKu/CSM_B_DeviceRuKu_MX') WITH CSM_B_DeviceRuKu_MX set @i=1 ---游标（主要作用是循环读取CSM_B_DeviceRuKu_MX中的数据） declare item_cursor cursor for SELECT DeviceMode,Amount FROM OpenXML(@idoc,'/CSM_B_DeviceRuKu/CSM_B_DeviceRuKu_MX') WITH CSM_B_DeviceRuKu_MX open item_cursor fetch next from item_cursor into @DeviceMode,@EquipAttribute,@Printerstyle,@Softedition,@Head,@Code,@Amount while @@Fetch_Status=0 begin ---只是打印出效果，现在@DeviceMode,@Amount 都以全部获得了值，可以对数据库表CSM_B_DeviceRuKu_MX表进行添加和修改 print('这是第'+cast(@i as varchar(20))+'次：：：'+@DeviceMode+','+@EquipAttribute+','+@Printerstyle+','+@Softedition+','+@Head+','+@Code+','+@Amount ) set @i=@i+1 fetch next from item_cursor into @DeviceMode,@Amount end close item_cursor deallocate item_cursor |
