我想每天运行cron job
来更新dadmin_reminder_date
,dshipment_date
和darrival_date
。我需要在每个当前日期添加icmd_days
。
实施例。对于第二行(无法上传图像)
输出应该是
old(05/07/2015)/new(06/04/2015),old(05/07/2015)/new(06/04/2015),old(05/15/2015)new(06/12/2015)
。此行的icmd_days = 28
。每行都有不同的天数或icmd_days
值。
这是我到目前为止的php
代码,但是它使用相同的天数更新每一行。
require '../commonincludefiles.php';
global $conn;
$row_string = '';
$Today = date("Y-m-d");
global $conn;
$sub_query = "SELECT bisubscriptionID,dshipment_date,darrival_date,icmd_days,dadmin_reminder_date,vsubscriptionstatus FROM tbl_subscription WHERE darrival_date <= '".$Today."' AND edelete='0' AND vsubscriptionstatus='Shipped'";
$sub_res = mysqli_query($conn,$sub_query);
$temp = array();
if (mysqli_num_rows($sub_res) >0) {
$i=0;
while($row = mysqli_fetch_array($sub_res)){
$temp[$i]['bisubscriptionID'] = $row['bisubscriptionID'];
$temp[$i]['icmd_days'] = $row['icmd_days'];
$temp[$i]['new_dshipment_date'] = date('Y-m-d', strtotime($row['dshipment_date'] . '+ '.$row['icmd_days'].'days'));
$i++;
$new_vsubscriptionstatus = 'Active';
$update_query = "UPDATE tbl_subscription SET vsubscriptionstatus='" . $new_vsubscriptionstatus . "',dshipment_date='" . $new_dshipment_date . "',tmodifydate=NOW() WHERE darrival_date <= '".$Today."' AND edelete='0' AND vsubscriptionstatus='Shipped' AND bisubscriptionID= $bisubscriptionID";
$update_res = mysqli_query($conn, $update_query);
}
}
?>
请放轻松我。我之前从未编过代码,并被交给了一个网站,以获得乐趣。

因此,您可以将更新语句更改为如下所示并同时删除所有选择:
UPDATE tbl_subscription
SET vsubscriptionstatus = '" . $new_vsubscriptionstatus . "'
,dshipment_date=DATEADD(d,icmd_days,shipment_date)
,tmodifydate=NOW()
WHERE darrival_date <= '".$Today."'
AND edelete='0'
AND vsubscriptionstatus='Shipped'
AND bisubscriptionID= $bisubscriptionID
日期添加会自动将ICMD_DAYS中的天数添加到shipment_date并相应地设置日期。
此外,您可以删除SQL中内置GETDATE()函数的当前逻辑:
UPDATE tbl_subscription
SET vsubscriptionstatus = '" . $new_vsubscriptionstatus . "'
,dshipment_date=DATEADD(d,icmd_days,shipment_date)
,tmodifydate=NOW()
WHERE darrival_date <= GETDATE()
AND edelete='0'
AND vsubscriptionstatus='Shipped'
AND bisubscriptionID= $bisubscriptionID
我猜你使用的是MySQL而不是SQL Server。以下是在MySQL中如何做到这一点。我还为我在服务器上创建的架构(称为stackoverflow)编写了示例代码。
我包含了drop table,以防你想在任何调整后重新运行代码。
USE stackoverflow;
DROP TABLE `tbl_subscription`;
CREATE TABLE `tbl_subscription` (
`dshipment_date` DATE NULL,
`icmd_days` INT NULL,
`darrival_date` DATETIME NULL,
`edelete` BIT NULL,
`csubscriptionstatus` VARCHAR(45) NULL,
`bisubscriptionID` BIGINT NULL,
`dadmin_reminder_date` DATE NULL,
`dprevious_shipment_date` DATE NULL,
`tmodifydate` DATETIME NULL
)
ENGINE = InnoDB;
INSERT INTO `tbl_subscription`
(
dshipment_date
,icmd_days
,darrival_date
,edelete
,csubscriptionstatus
,bisubscriptionID
,dadmin_reminder_date
,tmodifydate
)
SELECT
'2015-04-30' as dshipment_date
,30 as icmd_days
,null as darrival_date
,0 as edelete
,'Shipped' as csubscriptionstatus
,20150001 as bisubscriptionID
,null as dadmin_reminder_date
,NOW() as tmodifydate
UNION ALL
SELECT
'2015-05-10' as dshipment_date
,25 as icmd_days
,null as darrival_date
,0 as edelete
,'Shipped' as csubscriptionstatus
,20150002 as bisubscriptionID
,null as dadmin_reminder_date
,NOW() as tmodifydate
UNION ALL
SELECT
'2015-04-10' as dshipment_date
,30 as icmd_days
,'2015-04-13' as darrival_date
,0 as edelete
,'Shipped' as csubscriptionstatus
,20150003 as bisubscriptionID
,null as dadmin_reminder_date
,NOW() as tmodifydate
UNION ALL
SELECT
'2015-05-25' as dshipment_date
,20 as icmd_days
,'2015-05-28' as darrival_date
,0 as edelete
,'Active' as csubscriptionstatus
,20150004 as bisubscriptionID
,null as dadmin_reminder_date
,NOW() as tmodifydate
UNION ALL
SELECT
'2015-04-27' as dshipment_date
,20 as icmd_days
,'2015-04-30' as darrival_date
,0 as edelete
,'Shipped' as csubscriptionstatus
,20150005 as bisubscriptionID
,null as dadmin_reminder_date
,NOW() as tmodifydate
;
SELECT * FROM `tbl_subscription`;
SELECT dshipment_date,icmd_days,DATE_ADD(dshipment_date, INTERVAL icmd_days DAY) FROM `tbl_subscription`;
UPDATE `tbl_subscription`
SET dprevious_shipment_date = dshipment_date
,csubscriptionstatus = 'Active'
,dshipment_date=DATE_ADD(dshipment_date, INTERVAL icmd_days DAY)
,tmodifydate = NOW()
WHERE darrival_date <= NOW()
AND edelete='0'
AND csubscriptionstatus='Shipped'
/*AND bisubscriptionID= $bisubscriptionID -- this is not needed since we are not doing the loop anymore -- */
;
SELECT * FROM `tbl_subscription`;
但您需要的基本代码是:
USE stackoverflow;
UPDATE `tbl_subscription`
SET dprevious_shipment_date = dshipment_date
,csubscriptionstatus = 'Active'
,dshipment_date=DATE_ADD(dshipment_date, INTERVAL icmd_days DAY)
,tmodifydate = NOW()
WHERE darrival_date <= NOW()
AND edelete='0'
AND csubscriptionstatus='Shipped'
/*AND bisubscriptionID= $bisubscriptionID -- this is not needed since we are not doing the loop anymore -- */
此代码将消除循环设置csubscriptionstatus值的需要。
我在您的表格中添加了一个字段dprevious_shipment_date作为日期,以便您可以跟踪上个月发货的时间,以防您需要进行恢复,如果需要,您也可以从更新语句中删除它。
