php - 选择两个mysql表中的所有数据

标签 php mysql html-table

我这段代码用于连接数据库中的两个表。当尝试使用 while 循环回显它时，它没有显示任何错误消息，但它也没有显示任何内容。有人可以帮我吗？

$sql = "SELECT * FROM usr_details, paymnt_details WHERE usr_details.Trnsnubr = paymnt_details.Trnsnubr";

$sql = 
"SELECT *
FROM usr_details 
JOIN paymnt_details ON usr_details.Trnsnubr = paymnt_details.Trnsnubr";

这是我用于回显的 html 和 PHP 代码:

$rs_result = mysql_query ($sql) or die(mysql_error()); 
<table width="100%" height="109" border="1" cellpadding="2px" >
  <tr>
    <td colspan="5" class="mainheader">Registerd Persons</td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
    <td colspan="16"></td>
  </tr>
 <tr>
    <td class="tableheader" width="68">Payment</td>
    <td class="tableheader" width="64">Amount</td>
    <td class="tableheader" width="58">Date</td>
    <td class="tableheader" width="74">Trnsnubr</td>

    <td class="tableheader" width="40">Faly-mem-1-name</td>
    <td class="tableheader" width="40">Faly-mem-2-name</td>
    </tr>
<?php 
while ($row = mysql_fetch_assoc($rs_result)) {

最佳答案

如果这些表具有相同名称的列，则此请求将导致错误。发生这种情况是因为您尝试按列名称获取所有值。在困难的查询中尽量不要使用 *。

尝试这样做:

SELECT usr_details.*, paymnt_details.field1, paymnt_details.field2
FROM usr_details 
JOIN paymnt_details ON usr_details.Trnsnubr = paymnt_details.Trnsnubr

1

<?
$res = mysql_query("SELECT * FROM usr_details LIMIT 1");
var_dump(  mysql_fetch_assoc($res) );
$res = mysql_query("SELECT * FROM paymnt_details LIMIT 1");
var_dump(  mysql_fetch_assoc($res) );
$sql = "SELECT usr_details.* FROM usr_details LEFT JOIN paymnt_details ON usr_details.Trnsnubr = paymnt_details.Trnsnubr";
$res = mysql_query($sql);
var_dump($res);
while($row=mysql_fetch_assoc($res)) {
    var_dump($row);
}
var_dump( mysql_error() );
?>
