PHP在Oracle数据库中计算行数

Question

我正在尝试计算单个表中的总行数。只需要知道总共有多少行，没有别的。我正在使用Oracle数据库。

我试过了

$sql = "SELECT COUNT(*) AS homes FROM homes";

但我不确定如何显示结果。

Answer 1

$sql = "SELECT COUNT(*) AS count FROM homes";

Answer 2

<?php

    $link = mysqli_connect("host", "username", "password");
    mysqli_select_db("database", $link);

    $result = mysqli_query("SELECT * FROM homes", $link);
    $num_rows = mysqli_num_rows($result);

    echo "$num_rows Rows\n";

?>

Answer 3

从

计算行数

 $sql = "SELECT * FROM homes";  // fetch the rows
 $sql1=mysql_query($sql);
 $count=mysql_num_rows($sql1)  // count number of rows in table
 echo $count;  //$count has the value of rows in table..

Answer 4

使用此代码：

//代码在这里

$sql = "SELECT COUNT(*) AS homes FROM homes";
$result = mysqli_query($sql);
$row = mysqli_fetch_array($result);
