Php 验证多行之间的数据

MySQL数据库：

date       | avl | occ
----------------------
2014-11-12 |  2  |  3
2014-11-13 |  0  |  5
2014-11-14 |  1  |  4

$results = $con->query("SELECT * FROM table_name WHERE date BETWEEN '" . $check_in_date . "' AND  '" . $check_out_date . "' ORDER by avl DESC");
if ($results) {
    while($row = $results->fetch_array()) {
        $avl= $row['avl'];
        $date= $row['date'];
    }
}

我使用以下查询从MySQL数据库获取数据：

date       | avl | occ
----------------------
2014-11-12 |  2  |  3
2014-11-13 |  0  |  5
2014-11-14 |  1  |  4

$results = $con->query("SELECT * FROM table_name WHERE date BETWEEN '" . $check_in_date . "' AND  '" . $check_out_date . "' ORDER by avl DESC");
if ($results) {
    while($row = $results->fetch_array()) {
        $avl= $row['avl'];
        $date= $row['date'];
    }
}

现在我只想在

$check\u in\u date

和

$check\u out\u date

之间的

$avl

值大于

0

时打印

$check\u-in\u-date

提前谢谢。

好吧，在

WHERE

子句中加上另一个条件

例如：

$check_in_date = $con->real_escape_string($check_in_date);
$check_out_date = $con->real_escape_string($check_out_date);
$results = $con->query("SELECT * FROM table_name WHERE avl > 0 AND date BETWEEN '$check_in_date' AND '$check_out_date' ORDER by avl DESC");
if ($results->num_rows > 0) {
    while($row = $results->fetch_assoc()) {
        $avl = $row['avl'];
        $date = $row['date'];
    }
}
