两个问题。

这缺少一个结束括号：

  set @Result= (select a.account_link from ACCOUNTS a where account_id= @Acc_link

这缺少打开和关闭括号：

  set @Result = select a.account_link from ACCOUNTS a where account_id=@Result

你错过了一个 ) 就行了

set @Result= (select a.account_link from ACCOUNTS a where account_id= @Acc_link

也可以是其他东西，但请先尝试。

正确的程序如下：

create PROCEDURE [dbo].[Flag_Account]
AS 
begin 
DECLARE @Acc_link int, @Result int,@inc int,@Result2 int 
SET @inc = 0 
set @Result =0 
DECLARE A_Cursor CURSOR FOR Select account_id FROM ACCOUNTS 
OPEN A_Cursor
FETCH NEXT FROM A_Cursor INTO @Acc_link
WHILE @@FETCH_STATUS =0 
BEGIN
set @Result= (select a.account_link from ACCOUNTS a where account_id= @Acc_link 
while  @Result = 0
   begin 
      set @Result = select a.account_link from ACCOUNTS a where account_id=@Result 
     SET @inc= @inc+1 end update ACCOUNTS set flag_color=@inc where account_id= @Acc_link
     FETCH NEXT FROM A_Cursor INTO @Acc_link
   END
end
CLOSE A_Cursor 
DEALLOCATE A_Cursor 
end
