php - 当我向其添加日期范围时，我的查询将不起作用。使用 PHP 和 MySQL

Question

我目前在一个表单中有多个搜索字段，用户可以选择要过滤的字段，一切正常，直到我向其中添加日期范围。如果我单独添加日期范围而没有任何其他字段来过滤它，那么我知道这并不是我写错了查询。请帮我解决这个问题。谢谢!

这是有效的查询:(同样出于某种原因，执行 SELECT * 将不起作用，我必须键入要显示的所有字段的名称)

它包括表单中包含日期范围的部分。

<li class="form-line form-line-column" id="id_29">
    <label class="form-label-top" id="label_29" for="input_30">
        From Date:
    </label>
    <div id="cid_29" class="form-input-wide">
        <input type="text" class="form-textbox validate" id="datepicker" name="from_date" size="10" />
    </div>
</li>
<li class="form-line form-line-column" id="id_29">
    <label class="form-label-top" id="label_29" for="input_8">
        To Date:
    </label>
    <div id="cid_29" class="form-input-wide">
        <input type="text" class="form-textbox validate" id="datepicker2" name="to_date" size="10" />
    </div>
</li> 

<?php
    $sso = $_GET['sso'];
    $assigned_to = $_GET['assigned_to'];
    $case_status = $_GET['case_status'];
    $startdate = $_GET['from_date'];
    $enddate = $_GET['to_date'];
    $subject = $_GET['subject'];

    $sql = ("SELECT 
                id, sso, full_name, case_status, assigned_to, resolution, 
                description, updated, created, additional_notes, subject
            FROM rmstable2
            WHERE 
                sso LIKE '%$sso%' AND
                case_status LIKE '%$case_status%' AND
                assigned_to LIKE '%$assigned_to%' AND
                subject LIKE '%$subject%'");
?>

这是我想要的查询:

<?php
    $sql = ("SELECT 
                id, sso, full_name, case_status, assigned_to, resolution, 
                description, updated, created, additional_notes, subject
             FROM rmstable2
             WHERE 
                sso LIKE '%$sso%' AND
                case_status LIKE '%$case_status%' AND
                assigned_to LIKE '%$assigned_to%' AND
                subject LIKE '%$subject%'
                AND created >= '$startdate'
                AND created <= '$enddate'");
?>

为此使用 BETWEEN 并且不要忘记用 DATE( ) 包裹日期

$sql = ("SELECT id, sso, full_name, case_status, assigned_to, 
                resolution, description, updated, created, 
                additional_notes, subject 
        FROM  rmstable2 
        WHERE sso LIKE '%$sso%' AND 
              case_status LIKE '%$case_status%' AND 
              assigned_to LIKE '%$assigned_to%' AND 
              subject LIKE '%$subject%' AND 
              DATE(created) BETWEEN DATE('$startdate') AND DATE('$enddate')");

如何将 AND 更改为 OR

$sql = ("SELECT id, sso, full_name, case_status, assigned_to, 
                resolution, description, updated, created, 
                additional_notes, subject 
        FROM  rmstable2 
        WHERE sso LIKE '%$sso%' OR 
              case_status LIKE '%$case_status%' OR
              assigned_to LIKE '%$assigned_to%' OR 
              subject LIKE '%$subject%' OR
              (DATE(created) BETWEEN DATE('$startdate') AND DATE('$enddate'))");
