  • sql2000中,临时表循环插入数据需要指定插入列,否则会报错

    USE [hdykxin]
    GO
    
    /****** Object:  StoredProcedure [dbo].[pro_StudentExamScores]    Script Date: 08/27/2012 00:13:44 ******/

    	left join h_jxgl_ClassInfo [class] on exam.classid=[class].Id
    	where exam.id=@examId
    	select @length=LEN(@courses) --初始化LENGTH
    	if @length is not null and @length>0

    				insert into #scoreTable(ScoreId) 
    				select cj.id as ScoreId
    				from h_kscj_cjRecords cj
    				left join h_jxgl_kcManage kc on cj.SubjectId=kc.Id
    				where SubjectId=@activeCourse and ExamId=@examId
    				order by Score desc
    				
    				--每次插入数据之后删除临时表,保证排名从1开始
    				insert into h_kscj_examRanking
    				select ScoreId,ID from #scoreTable
    				drop table #scoreTable
    				
    			end
    			
    		end
    		--总分数排名
    		create table #SumscoreTable  --创建临时表#scoreTable 用来进行排名
    				(
    					ID   int IDENTITY (1,1)     not null, -- 排名
    					ScoreId int --考试科目成绩ID
    				);
    				
    				insert into #SumscoreTable(ScoreId) 
    				select cj.id as ScoreId
    				from h_kscj_cjRecords cj
    				left join h_jxgl_kcManage kc on cj.SubjectId=kc.Id
    				where SubjectId=0 and ExamId=@examId
    				order by Score desc
    				
    				--每次插入数据之后删除临时表,保证排名从1开始
    				insert into h_kscj_examRanking
    				select ScoreId,ID from #SumscoreTable
    				drop table #SumscoreTable
    				
    	end
    	
    	if(@@error>0)
    		begin 
    		select @resultAction=0
    		rollback transaction
    		end
    	else
    		begin 
    		select @resultAction=1
    		commit transaction
    		end
    	
        -- 最后的查询结果
    	select @resultAction as result
    END
    
    
    GO
    

      结果会导致错误:“当 IDENTITY_INSERT 设置为 OFF 时,不能向表 'products' 中的标识列插入显式值。”
