(Sqlserver)将在查询结果插入新表中的时候添加一个自动增长列么 SQL语句怎么写

如题

假设表有主键ID列，以下生成比原表多一个序号列并按ID号大小填充的新表。
select 序号=(select count(1) from tablename a where a.id>=tablename.id),* from tablename 参考技术A select identity(int,1,1) as x ,* insert into newtbfrom oldtb 参考技术B 用ROW_NUMBER() over(order by 排序列 asc) 不就可以了？

Oracle 定时查询数据插入新表中（job+存储过程）

create table EGMAS_COUNT_DATA
(
TIMES       date not null,
COUNT NUMBER(30) not null,
SYSTEM_NAME VARCHAR2(30) not null,
Operation_index VARCHAR2(30) not null
);
-- Add comments to the columns
comment on column EGMAS_COUNT_DATA.TIMES
is ‘日期‘;
comment on column EGMAS_COUNT_DATA.COUNT
is ‘统计量‘;
comment on column EGMAS_COUNT_DATA.SYSTEM_NAME
is ‘系统编码‘;
comment on column EGMAS_COUNT_DATA.Operation_index
is ‘业务运营指标名称‘;

存储过程：

create or replace procedure orderCount is

  begin

   

    insert into EGMAS_COUNT_DATA(DAY, COUNT,SYSTEM_NAME,Operation_index)

    SELECT to_date(to_char(sysdate-1,‘yyyy-MM-dd‘),‘yyyy-MM-dd‘), (select count(1) from T_ORDERS WHERE ORDER_RESOURCE = ‘13‘

    AND to_char(CREATED_TM,‘yyyy-MM-dd‘) = to_char(sysdate-1,‘yyyy-MM-dd‘)), ‘EGMAS‘,‘Android手机订单量(港澳台)‘

    FROM dual;

    insert into EGMAS_COUNT_DATA(DAY, COUNT,SYSTEM_NAME,Operation_index)

    SELECT to_date(to_char(sysdate-1,‘yyyy-MM-dd‘),‘yyyy-MM-dd‘), (select count(1) from T_ORDERS WHERE ORDER_RESOURCE = ‘14‘

    AND to_char(CREATED_TM,‘yyyy-MM-dd‘) = to_char(sysdate-1,‘yyyy-MM-dd‘)), ‘EGMAS‘,‘IPHONE手机订单量(港澳台)‘

    FROM dual;

    insert into EGMAS_COUNT_DATA(DAY, COUNT,SYSTEM_NAME,Operation_index)

    SELECT to_date(to_char(sysdate-1,‘yyyy-MM-dd‘),‘yyyy-MM-dd‘), (select count(1) from T_ORDERS WHERE

    to_char(CREATED_TM,‘yyyy-MM-dd‘) = to_char(sysdate-1,‘yyyy-MM-dd‘)), ‘EGMAS‘,‘速运通订单量(港澳台)‘

    FROM dual;

    commit;

  end orderCount;

/

 

设置job执行时间：

         variable jobno number;

begin

  dbms_job.submit(:jobno,‘orderCount;‘, sysdate, ‘TRUNC(sysdate+1)+1/24‘);

end;

/

 

启动job：

 

begin

dbms_job.run(44);

commit;

end;

/

 

查看job是否存在：

select job, next_date, next_sec, failures, broken from user_jobs;
