大量插入SQL-Oracle 11g

Question

我需要一个查询，以便在从今天起的过去N天内将行插入表中。

Insert into Table select 'xpto', name 
from users where login_date between 
    TO_DATE(:DATE || ' 00:00:00', 'mm/dd/yyyy HH24:MI:SS') 
and TO_DATE(:DATE || ' 23:59:59', 'mm/dd/yyyy HH24:MI:SS')

我需要此：DATE代表最近30天...（每天）..因此，它将是30个插入。

我怎样才能做到这一点？

假设我要插入最近30天的数据...因此，我们有：

01/18/2016
01/19/2016
01/20/2016
...
02/01/2016
02/02/2016
02/03/2016
....
02/15/2016
....
02/22/2016

我想要一个查询-或语句-根据上述每一天插入我的数据，如下所示：

Insert into Table select 'xpto', name 
from users where login_date between 
    TO_DATE('01/15/2016' || ' 00:00:00', 'mm/dd/yyyy HH24:MI:SS') 
and TO_DATE('01/15/2016' || ' 23:59:59', 'mm/dd/yyyy HH24:MI:SS')
--- another insert
Insert into Table select 'xpto', name 
from users where login_date between 
    TO_DATE('01/16/2016' || ' 00:00:00', 'mm/dd/yyyy HH24:MI:SS') 
and TO_DATE('01/16/2016' || ' 23:59:59', 'mm/dd/yyyy HH24:MI:SS')

我不想每天查询一次...

对不起，我只是把我的工作笔记本放在这里...这是真实的示例：

BEGIN
for day in (SELECT to_char(TO_DATE (SYSDATE, 'dd/mm/yyyy')-30 + LEVEL) AS DATE_CHECK
      FROM DUAL
CONNECT BY SYSDATE - 30 + LEVEL <= SYSDATE)
  LOOP
  v_date := to_char(day.date_check);
  INSERT INTO resume (date_check, type, total)
SELECT   v_data AS DATA, type, COUNT (*) total
    FROM ( select ....
 from table
 WHERE DATE_COLUMN BETWEEN TO_DATE(v_data ||' 00:00:00', 'dd/mm/yyyy hh24:mi:ss') and TO_DATE(v_date || ' 23:59:59', 'dd/mm/yyyy hh24:mi:ss')
union 
select ....
 from table
 WHERE DATE_COLUMN BETWEEN TO_DATE(v_data ||' 00:00:00', 'dd/mm/yyyy hh24:mi:ss') and TO_DATE(v_date || ' 23:59:59', 'dd/mm/yyyy hh24:mi:ss')
)

end loop;
end;

但是它不起作用...如果我执行相同的插入操作，请用任意日期（14/02/2016）手动替换v_date。

如果我了解您要正确执行的操作，则可能会起作用：

Insert into Table
  select 'xpto', name 
    from users
    where login_date between TRUNC(SYSDATE) - INTERVAL '30' DAY
                         and TRUNC(SYSDATE) + INTERVAL '1' DAY - INTERVAL '1' SECOND

根据对问题的编辑，似乎我们可以扩大范围，如下所示：

Insert into Table
  select 'xpto', name 
    from users
    where login_date between TO_DATE('01/18/2016', 'MM/DD/YYYY') 
                         and TO_DATE('02/22/2016', 'MM/DD/YYYY') + INTERVAL '1' DAY - INTERVAL '1' SECOND

谢谢您的澄清。 也许以下方法会有所帮助：

BEGIN
  for day in (SELECT TRUNC(SYSDATE)-30 + LEVEL AS DATE_CHECK
                FROM DUAL
                CONNECT BY TRUNC(SYSDATE) - 30 + LEVEL <= TRUNC(SYSDATE))
  LOOP
    INSERT INTO resume (date_check, type, total)
      SELECT day.DATE_CHECK AS DATA, type, COUNT (*) total
        FROM (select ....
                from table
                WHERE DATE_COLUMN = TRUNC(day.DATE_CHECK));
  end loop;
end;

祝你好运。
