php - sql查询显示2个日期之间的所有行

Question

我有一个名为预订详细信息的 SQL 表，其中包含以下列:

Booking_Id
Room_Id
Booking_Date
Check_in_Date
Check_out_Date

我想查看 2 个日期范围内的所有数据行。例如:

$start='2017-04-15' 和 $end='2017-04-25'

sql 查询应仅显示位于这两个日期范围之间的行。

SELECT * FROM booking_details
WHERE '2017-04-15' BETWEEN '2017-04-15' AND '2017-04-25'
OR '2017-04-25' BETWEEN '2017-04-15' AND '2017-04-25'

SELECT * FROM booking_details
WHERE '2017-04-15' BETWEEN '2017-04-15' AND '2017-04-25'

SELECT * FROM booking_details
WHERE '2017-04-15' >='2017-04-15' AND '2017-04-15'<='2017-04-25'

我的编码有问题吗？查看编码并让我知道问题:

Answer 1

如果您尝试获取开始日期和结束日期之间的预订日期。试试这个。

从 booking_details 中选择 * WHERE Booking_Date BETWEEN $start AND $end

<div class="wrapper row3">
<div id="breadcrumb" class="clear"> 
<header id="header" class="clear">
<h1><font size="5"><u>VIEW BOOKING - HOTEL DAFFODILS</u></font></h1>
</header>
<br>
<?php
    if(isSet($_SESSION['name']))
    {
        echo "<font color=#737373 size=5> WELCOME ".$_SESSION['name']." !</font><br>";
    }
    echo "<br>";
    if(isSet($_SESSION['email']))
    {
        $a=$_POST["data_1"];
        $b=$_POST["data_2"];
        date_default_timezone_set('Asia/Calcutta');
        $start=date("Y-m-d", strtotime($a));
        $end=date("Y-m-d", strtotime($b));
        $diff = abs(strtotime($end) - strtotime($start));
        $days = $diff/86400;
        $date=date("Y-m-d");

        $_SESSION['start']=$start;
        $_SESSION['end']=$end;
        $_SESSION['date']=$date;
        $_SESSION['days']=$days;

        include 'db_config.php';
        if($start<= $end)
        {
            $sql="SELECT * FROM booking_details WHERE ".$date." >= Check_in_Date AND ".$date." <= Check_out_Date";

            if ($result->num_rows > 0) 
            {
