[英]Split date range and get combined results in mysql
我有兩張桌子
orders_status_history
id | order_id | status | date
1 | 1201 | 2 | 2015-01-20
2 | 1124 | 4 | 2015-02-01
3 | 1245 | 1 | 2015-02-14
4 | 1365 | 2 | 2015-03-10
saved_shipping_invoices
id | order_id | product_id | date
1 | 1348 | 12541 | 2015-12-18
2 | 1298 | 11485 | 2016-01-02
3 | 1319 | 14521 | 2016-05-14
4 | 1441 | 10124 | 2016-05-14
和一年的日期范圍即
$start_date = '2015-09-30';
$end_date = '2016-09-30';
表“shipping_invoice_history”中的數據從2015-12-18開始。 現在我想打破2015-12-18的日期間隔。 現在將有兩個間隔
$interval1_start = '2015-09-30';
$interval_end = '2015-12-17';
$interval2_start = '2015-12-18';
$interval2_end = '2016-09-30';
當它打破日期間隔時,我想在第一個時間間隔從表“orders_status_history”獲取數據,但是在第二個時間間隔,它從“shipping_invoice_history”獲取數據。我還需要在單個表中顯示數據。
$week = '2015-09-30 @@ 2016-09-30';
$week_ranges = explode('@@', $week);
if ($week_ranges[0] > '2015-12-18' )
{
$invoices_shipped_qty = tep_db_query("SELECT * FROM `saved_shipping_invoices` WHERE `date_created` BETWEEN '".$week_ranges[0]."' AND '".$week_ranges[1]."'");
$invoices_shipped_arr = tep_db_fetch_array($invoices_shipped_qty);
$total_sent = $invoices_shipped_arr['shiped_qty'];
}
else {
$total_order_status_complete = tep_db_query("SELECT * FROM `orders_status_history` WHERE `orders_status_id` = '17' AND `date_added` BETWEEN '".$week_ranges[0]." 00:00:00' AND '".$week_ranges[1]." 23;59:59'");
$total_order_status_complete_arr = tep_db_fetch_array($total_order_status_complete);
請建議我如何將日期間隔分成兩部分,從兩個表中獲取結果並在單次運行中顯示。
可能這就是你想要的
select
'order_status_history' as table,
id,
order_id,
status,
null as product_id,
date from order_status_history
where
date between '2015-09-30' and '2015-12-17'
union all
select
'saved_shipping_invoices' as table,
id,
order_id,
null as status,
product_id,
date
from saved_shipping_invoices
where
date between '2015-12-18' and '2016-09-30'
根據查詢的動態程度,我喜歡這樣做而不是聯合。
我更喜歡這個選項:
select
if(date <='2015-12-17', 'Phase 1',
if(date >='2015-12-18', 'Phase 2',
'None')),
id,
order_id,
status,
null as product_id,
date from order_status_history
where
date between '2015-09-30' and '2016-09-30'
要么
select
if(date between '2015-09-30' and '2015-12-17', 'Phase 1',
if(date between '2015-12-18' and '2016-09-30', 'Phase 2',
'None')),
id,
order_id,
status,
null as product_id,
date from order_status_history
where
date between '2015-09-30' and '2016-09-30'
