遍历数据库全部表，将是datetime类型的列的值进行更新

declare @tablename nvarchar(80)

  declare @cloumn nvarchar(80)

  declare @sql nvarchar(400)

declare c1 cursor scroll for

 select table_name,column_name from information_schema.columns where DATA_TYPE='datetime'

 open c1

  fetch first from c1 into @tablename,@cloumn

  while @@fetch_status=0

   begin

      

      set @sql='update '+@tablename+' set 
'+@cloumn+'=DATEADD(yy,10,'+@cloumn+')  where
'+@cloumn+' is not null';

      exec (@sql)

     fetch next from c1 into @tablename,@cloumn

close c1
