动态sql,将某个指定的数据库的所有表导出

1.导出某个数据库全部的表到xml(既要表结构，也要表的内容)
 
            

if object_id('tempdb.dbo.#tmpTableName') is not null
                     drop table #tmpTableName  --删除临时表  
   
                     use BugManager select name,ROW_NUMBER() OVER(ORDER BY name) as Item into #tmpTableName from sys.Objects where type='U' order by name
  
                     declare @sSql varchar(max)='' 
                         select @sSql=@sSql + '
                                 select * from ' + name from #tmptablename
                     exec(@sSql)                    
                     use BugManager select name,ROW_NUMBER() OVER(ORDER BY name) as Item from sys.Objects where type='U' order by name 2.导出某个数据库全部的表结构(不要表里的内容)

                         select @sSql=@sSql + '
                                 select * from ' + name + ' where 1=0 ' from #tmptablename 
                     exec(@sSql)----------------------------------

在C#中，将上面查询得到的结果放到 dataset中，然后通过dataset 的WriteXml 方法，可以导出到xml文件中.
