mysql_select_db（不选择数据库

-5

我遇到了mysql_select_db()功能不选择正确的数据库的一个问题我的代码如下：mysql_select_db（不选择数据库

global $file_count; 


    $conlivedata = mysql_pconnect("localhost","*****","*****"); 
     if (!$conlivedata) { 
     echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
    } 
    $con = mysql_pconnect("***************","*****","*****"); 
    if (!$con) { 
     echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
    } 
    mysql_select_db("csv_db", $con)or die("A MySQL error has occurred.Your Query: Error: (" . mysql_errno() . ") " . mysql_error()); 

    $result = mysql_query("SELECT * FROM `tbl_name` WHERE EmailAddr <> ' ' ORDER BY `EmailAddr`") or die("<br/>A MySQL Query error has occurred.Your Query: Error: (" . mysql_errno() . ") " . mysql_error()); 

    while($row = mysql_fetch_array($result)) 
    { 
     echo $row['first_name'] . " " . $row['last_name']; 
     $Email = $row['EmailAddr']; 
     if ($Email != NULL){ 
      mysql_select_db("foswood_db", $conlivedata) or die("<br/>A MySQL error has occurred Slecting Database.<br />Your Query: <br/> Error: (" . mysql_errno() . ") " . mysql_error()); 
      $liveresult = mysql_query("SELECT COUNT(*) FROM pledges WHERE EmailAddr = '$Email'") or die("<br/>A MySQL error has occurred.<br />Your Query: <br /> Error: (" . mysql_errno() . ") " . mysql_error()); 
      if(mysql_result($liveresult, 0)) echo ': **Voted**';; 
      mysql_select_db("csv_db", $con) or die("<br/>A MySQL error has occurred Slecting Database.<br />Your Query: <br /> Error: (" . mysql_errno() . ") " . mysql_error()); 
     } 
     echo "<br />"; 
    } 

    mysql_close($con); 
    mysql_close($conlivedata);

我得到的错误信息：

A MySQL error has occurred. 
Your Query: 
Error: (1146) Table 'csv_db.pledges' doesn't exist

有没有人任何想法为什么请？

我想你已经有了你的答案。 – hjpotter92 2013-03-23 11:54:24

再次检查你的表名，还为什么你声明了mysql_select_db 2次？ – 2013-03-23 11:56:35

@DevangRathod有两个不同的连接。 – hjpotter92 2013-03-23 11:58:04

您应该指定用于查询的数据库。

$result = mysql_query("SELECT * FROM `tbl_name` WHERE EmailAddr <> ' ' ORDER BY `EmailAddr`", **$con**) ...

我不得不奇怪地重写与打开第一个连接的代码。这解决了这个问题。 – 2013-03-24 19:25:45
