关于SqlServer 查询自增列的问题

说明：hzyl_bc_zyfymxb  表里 detailid列为主键，不允许重复；zyh为主键，允许重复，现在想给一个住院号里多增加点detailid不同的本表记录，但是detailid相同zhy的不允许重复，所以用到自增列：
第一步：

SELECT top 2000  195900000054763001 as zyh
     ,detailid=IDENTITY(int,1000,1)
     ,[sfrq]
     ,[xmlx]
     ,[xmyybm]
     ,[xmzxbm]
     ,[xmmc]
     ,[xmgg]
     ,[xmdw]
     ,[xmdj]
     ,[sl]
     ,[je]
     ,[zf_je]
     ,[operid]
     ,[isupload]
     ,[hylx] into #temp
  FROM [hzyl_qzj0710].[dbo].[hzyl_bc_zyfymxb];

第二步：

INSERT INTO [hzyl_qzj0710].[dbo].[hzyl_bc_zyfymxb]           ([zyh]          ,[detailid]          ,[sfrq]          ,[xmlx]          ,[xmyybm]          ,[xmzxbm]          ,[xmmc]          ,[xmgg]          ,[xmdw]          ,[xmdj]          ,[sl]          ,[je]          ,[zf_je]          ,[operid]          ,[isupload]          ,[hylx])select * from #temp
