这是哪里错了，看了很久，求情帮忙！
declare   @table_name   varchar(20)
declare   @strSql   nvarchar(4000)
declare   @rscount   int
declare   table_cursor   CURSOR   For
select   [name]   from   sysobjects   where   type= 'u '
open   table_cursor

    fetch   next   from   table_cursor   into   @table_name  
  end
CLOSE   table_cursor
DEALLOCATE   table_cursor


exec   sp_executesql   @strSql   语法错误！
