Sample: SQL 2008循环所有表和所有列

其实很简单，相对于SQL 2000改了sys.all_objects和sys.columns

declare @tblname varchar(200)<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

declare @object_id int

declare tbl_cursor CURSOR for

select name,object_id from sys.all_objects where type='u'

open tbl_cursor

FETCH NEXT FROM tbl_cursor

INTO @tblname,@object_id

while @@FETCH_STATUS = 0

Begin

declare @str varchar(8000)

declare @selectstr varchar(2000)

set @selectstr=''

set @str='INSERT INTO '+ @tblname +'('

--print @tblname,@object_id

declare @colname varchar(200)

declare col_cursor CURSOR for

select name from sys.columns where object_id=@object_id order by column_id

open col_cursor

FETCH NEXT FROM col_cursor INTO @colname

WHILE @@FETCH_STATUS = 0

BEGIN

set @str=@str+@colname+','

--Print @str

set @selectstr=@selectstr+@colname+','

--Print @colname

FETCH NEXT FROM col_cursor INTO @colname

END

close col_cursor

deallocate col_cursor

set @str=substring(@str,0,len(@str))

set @selectstr=substring(@selectstr,0,len(@selectstr))

set @str=@str+') SELECT ' + @selectstr +' FROM '+ @tblname

Print @str

fetch next from tbl_cursor into @tblname,@object_id

End

close tbl_cursor

deallocate tbl_cursor
