Sql 多查询日期范围

我每天都要运行多个查询，是否有办法为多个选择设置日期范围，而不是在每个选择中输入日期。我使用oracle sql developer来运行这些查询

下面是三个示例，但有十几个查询：

select count(*)"Tall ord"
from cr_ordpar
inner join cr_palhis on cr_palhis.pikref = cr_ordpar.pikref
inner join CR_LODHED_DESP on cr_lodhed_desp.ilodno = cr_ordpar.ILODNO
where cr_palhis.hstdat between '24-nov-15 07:00' and '25-nov-15 07:00:00'
and hststs_str = 'Pallet Output From Racking'
and cr_palhis.palhgt = '2700'
order by cr_lodhed_desp.lodref;

select count(*)"Tall del"
from cr_palhis
where cr_palhis.hstdat between '24-nov-15 07:00' and '25-nov-15 07:00:00'
and hststs_str = 'Pallet Deleted'
and cr_palhis.palhgt = 2700
and cr_palhis.rakblk <> 510; 

select  count(*)"Tall ind"
from cr_palhis
where cr_palhis.hstdat between '24-nov-15 07:00' and '25-nov-15 07:00:00'
and hststs_str = 'Pallet Indexed'
and cr_palhis.PALHGT = '2700';

你的约会有很多问题

首先，“24-nov-15 07:00”不是日期，而是字符串。必须始终使用TO_DATE将文字显式转换为日期。此外，如果您没有提到NLS_DATE_语言，请记住，日期取决于NLS。NOV在其他语言中不一样

YY格式在很久以前就被认为是Y2K错误，全世界已经看到了摆脱它的努力。提及完整的YYYY或使用RR格式，但在实施之前要理解它

可以使用GROUPBY子句在单个查询中获取不同的计数。考虑到所有条件都保持不变

SELECT hststs_str,
  COUNT(*) cnt
FROM cr_ordpar
INNER JOIN cr_palhis
ON cr_palhis.pikref = cr_ordpar.pikref
INNER JOIN CR_LODHED_DESP
ON cr_lodhed_desp.ilodno = cr_ordpar.ILODNO
WHERE cr_palhis.hstdat 
BETWEEN TO_DATE('24-nov-2015 07:00','dd-mon-yyyy hh24:mi','nls_date_language=ENGLISH') 
AND     TO_DATE('25-nov-2015 07:00','dd-mon-yyyy hh24:mi','nls_date_language=ENGLISH')
AND hststs_str       IN( 'Pallet Output From Racking', 
                         'Pallet Deleted', 
                         'Pallet Indexed'
                       )
AND cr_palhis.palhgt  = '2700'
AND cr_palhis.rakblk <> 510
GROUP BY hststs_str
ORDER BY cnt;

“24-nov-15 07:00”不是日期，而是字符串。cr_palhis.hstdat的数据类型是什么？我的问题是如何操纵最终结果。它只是一个报告，还是我们需要将它传递给其他前端工具？

SELECT hststs_str,
  COUNT(*) cnt
FROM cr_ordpar
INNER JOIN cr_palhis
ON cr_palhis.pikref = cr_ordpar.pikref
INNER JOIN CR_LODHED_DESP
ON cr_lodhed_desp.ilodno = cr_ordpar.ILODNO
WHERE cr_palhis.hstdat 
BETWEEN TO_DATE('24-nov-2015 07:00','dd-mon-yyyy hh24:mi','nls_date_language=ENGLISH') 
AND     TO_DATE('25-nov-2015 07:00','dd-mon-yyyy hh24:mi','nls_date_language=ENGLISH')
AND hststs_str       IN( 'Pallet Output From Racking', 
                         'Pallet Deleted', 
                         'Pallet Indexed'
                       )
AND cr_palhis.palhgt  = '2700'
AND cr_palhis.rakblk <> 510
GROUP BY hststs_str
ORDER BY cnt;
