Question

我需要从mysql表中获取多行或单行，但我的代码只从表中检索数据，如我的where子句条件为true，即使我的条件为真，也不会获取单行。 PLZ建议我任何人。（我只知道一点点英语）

<?php 
include 'connection/db_connection.php';

 $sqlquery=mysql_query("select * from sadmin_invoiceno order by sno desc");
 $row1=mysql_fetch_assoc($sqlquery);
    $invoice=$row1['invoice_no'];
    /* if($row1['invoice_no']<=9)
    {
    $myvalue=$row1['invoice_no'];
    $idvalue="".$myvalue;   
    }
    if($row1['invoice_no']>9 && $row1['sno']<100)
    {
    $myvalue=$row1['invoice_no'];
    $idvalue="".$myvalue;   
    } */
        $sql="SELECT * FROM sadmin_sales where invoice_no='".$invoice."'";
        $result = mysql_query($sql);
        $count=mysql_num_rows($result);



?>

我不确定我完全理解你的问题，你是说你有多行而只想要一个？

如果是这样，请查看MySQL＆＃34; LIMIT＆＃34;这会将您的SQL查询限制为X行数，例如SELECT * FROM sadmin_customer where email='".$franchies." LIMIT 1

这将只返回1行，条件为真的第一行。

mysql_fetch_array（），在我的程序中不起作用
