插入最大 + 1 个 entry_sr_no 的重复记录

Question

我有一个 SP，它返回给我相应 文档编号 的最大条目编号。

现在我想要的是，我想在 inward_doc_tracking_trl 表中插入相同的记录，最大 + 1 entry_sr_no

说吧，

doc_no 的Max_Entry_Srno = IW/16/5694 为 3， 然后在trl 表中插入相同的Max_Entry_Srno 应该是4。

这是我的 SP

 ALTER procedure set_auto_action  
       as   
        begin         
             select hdr.mkey, hdr.doc_no, MAX(trl.entry_sr_no) as Max_Entry_Srno  
              from inward_doc_tracking_hdr hdr  
               JOIN inward_doc_tracking_trl trl  
             ON(hdr.mkey = trl.ref_mkey)  
              where hdr.status_flag     not in (5,13)   
             and trl.U_Datetime < DATEADD(DAY, -1, GETDATE())       
             GROUP BY hdr.mkey, hdr.doc_no  
       end

另见SP返回结果的截图

inward_doc_tracking_trl的表格脚本也在下面：-

注意：添加 max+ 1 sr_no 的重复行的原因是让用户知道该用户收到了文档
