下面的代码是我到目前为止所拥有的，如果有人对 BETWEEN 的工作原理有任何了解并且可以为我指明正确的方向，我将不胜感激。
<form action="index.php" method="GET">
Starting from:<br>
<input type="date" name="startDate" ><br><br>
Upto:<br>
<input type="date" name="uptoDate" ><br><br>
<input type="submit">
</form>
<?php
// I removed the connection details for obvious reasons
// It does connect and display the data with no problems
$startingFrom = $_GET[startDate];
$upto = $_GET[uptoDate];
// I tried this but it does not seem to work
// $query = "SELECT * FROM table BETWEEN $startingFrom AND $upto";
$query = "SELECT * FROM table";
$result = mysql_query($query);
echo "<table><th>Name</th><th>Registered Date</th>";
while($row = mysql_fetch_array($result)){
echo "<tr><td>" . $row['name'] . "</td><td>" . $row['registered'] . "</td></tr>";
}
echo "</table>";
mysql_close();
?>
如果您在两个给定日期之间返回结果，请使用此代码
SELECT *
FROM table
WHERE date BETWEEN CAST('2015-04-03' AS DATE) AND CAST('2015-05-28' AS
DATE);
对于带日期的 BETWEEN，您需要使用 CAST() 将值转换为适当的数据类型，例如 DATE 或 DATETIME。如果您使用 BETWEEN 和 DATETIME 将您的值转换为 DATETIME：
SELECT *
FROM table
WHERE date BETWEEN CAST('2015-04-03 08:40:09' AS DATETIME) AND CAST('2015-05-28 02:50:09' AS DATETIME);
作为旁注，使用 MySQL 改进的扩展 (mysqli) 并且您忘记关闭输入字段，这不是一个好的代码。
