Oracle-返回范围内每个日期的列

假设我有表A：援助

PersonID        Date           CHECK
123456       2012-01-01          F
213415       2012-01-03          A

PersonID    ArrivalDate       Jan-01    Jan-02    Jan-03    
123456       2012-01-01          F       NULL      NULL         
213415       2012-01-03         NULL     NULL       A

该系统用于检查，检查时间为1至15天，但不得超过15天。如果您有任何想法，我将不胜感激。

您可以试试这个，但我不确定这是否是您需要的

with inputs_
  as (select 123456 person_id, to_date('2012-01-01', 'YYYY-MM-DD') date_, 'F' check_
       from dual
      union all
      select 213415 person_id, to_date('2012-01-03', 'YYYY-MM-DD'), 'A' check_
        from dual
      UNION ALL
      select 123456 person_id, to_date('2012-01-01', 'YYYY-MM-DD') date_, 'F' check_

而且这不是动态的，所以如果您想要动态透视，您可以看到这个链接，

您可以使用查询为透视的IN子句构造最小日期到最大日期范围内的动态日期值。然后在PIVOT的in子句中打开一个带有所需参数的动态游标。 DBMS_SQL.RETURN_RESULT 12c及更高版本将显示所需的结果。 对于旧版本，您可以在此处参考我的答案，以便轻松显示光标的输出：

在普通SQL中，只有在预先确定列数而不是在读取输入数据之后，并且列名及其顺序也必须事先知道的情况下，才能执行此操作。否则，您需要动态SQL advanced，而且通常不推荐这样做，或者您可以在报表应用程序中而不是在SQL中执行此操作—这是执行此类格式化的更好地方。

DECLARE
  v_instring VARCHAR2 (1000);
  v_cur SYS_REFCURSOR;
BEGIN
WITH dt ( min_t ,max_t ) AS
  ( SELECT MIN(Date_t) ,MAX(Date_t) FROM TableA
   ) ,
  datevalues (date_ch) AS
  (SELECT TO_CHAR(min_t + lvl - 1, 'DD-MON')
  FROM dt CROSS APPLY
    ( SELECT LEVEL lvl FROM DUAL CONNECT BY LEVEL <= max_t - min_t + 1
    )
  )
SELECT LISTAGG(''''
  || date_ch
  || ''' AS "'
  || date_ch, '",') WITHIN GROUP (
ORDER BY date_ch )||'"'
INTO v_instring
FROM
  ( SELECT DISTINCT date_ch FROM datevalues
  );
OPEN v_cur FOR 'select * from (select  PersonID, date_t arrival_date, check_t,
TO_CHAR(date_t, ''DD-MON'') date_t from TableA) pivot ( min(check_t) 
for date_t in ('||v_instring||')) ORDER BY arrival_date';

DBMS_SQL.RETURN_RESULT(v_cur);
