PHPExcel列未找到：1054

我想将一个mysql查询表导出到excel文件。我有它在我的网站上的另一个页面上工作，但它似乎遇到此特定查询的麻烦。我得到这个错误：PHPExcel列未找到：1054

Warning: PDO::query() [pdo.query]: SQLSTATE[42S22]: Column not found: 1054 
Unknown column 'u2.confirmed_cash' in 'field list' in 
/home2/jtdsdevc/public_html /rbk/usage-v3/inc/excel-exporter 
/MySqlExcelBuilder.class.php on line 130

这是我的代码。

// Setup the SQL Statements 
$sql_statement = getReport($idLeague, $idTeam); 

function getReport($idLeague, $idTeam){ 
global $connect; 

$sql = " 
    SELECT idPlayer AS id, 
    (SELECT CONCAT_WS(' ', location, name) FROM `team` WHERE `team`.id = u.idTeam) AS team, 
    (SELECT CONCAT_WS(' ', first_name, last_name) FROM `player` WHERE `player`.id = u.idPlayer) AS name, 
    (SELECT u2.confirmed_cash FROM `usage` u2 WHERE u.idPlayer = u2.idPlayer ORDER BY date DESC LIMIT 1) AS total_cash, 
    (SELECT u2.confirmed_product FROM `usage` u2 WHERE u.idPlayer = u2.idPlayer ORDER BY date DESC LIMIT 1) AS total_product, 
    max(date) AS last_entry 
    FROM `usage` u INNER JOIN `team` t ON u.idTeam =t.id INNER JOIN `league` l ON t.idLeague =l.id WHERE (t.idleague =".$idLeague." or l.pID =".$idLeague.") 
    "; 

return $sql; 
} 

// Add the SQL statements to the spread sheet 
$mysql_xls->add_page('Report',$sql_statement); 

// Get the spreadsheet after the SQL statements are built... 
$phpExcel = $mysql_xls->getExcel(); // This needs to come after all the pages have been added. 
....

这就是错误发生的地方。在MySqlExcelBuilder.class.php文件的确切行是：

if ($sh = $this->pdo->query($sql))

的$sql变量上面出来是

SELECT idPlayer AS id, 
(SELECT CONCAT_WS(' ', location, name) FROM `team` WHERE `team`.id = u.idTeam) AS team, 
(SELECT CONCAT_WS(' ', first_name, last_name) FROM `player` WHERE `player`.id = u.idPlayer) AS name, 
(SELECT u2.confirmed_cash FROM `usage` u2 WHERE u.idPlayer = u2.idPlayer ORDER BY date DESC LIMIT 1) AS total_cash, 
(SELECT u3.confirmed_product FROM `usage` u3 WHERE u.idPlayer = u3.idPlayer ORDER BY date DESC LIMIT 1) AS total_product, 
max(date) AS last_entry 
FROM `usage` u 
INNER JOIN `team` t ON u.idTeam =t.id 
INNER JOIN `league` l ON t.idLeague =l.id 
WHERE (t.idleague =1 or l.pID =1)

编辑：还值得一提的是，通过自身的查询中工作正常phpMyAdmin的。

那么列'usage.confirmed_cash'是否存在？不确定它是否在'SELECT'列表中很重要，但是您使用别名'u2'作为两个不同的查询。将第二个更改为不同的别名。 – 2012-07-18 17:20:59

我按照你的建议做了，仍然没有骰子。该列确实存在于表中，事实上，当我将复制/粘贴该查询（并将变量替换为phpMyAdmin）时，它工作得很好！ – Falantar014 2012-07-18 18:08:07

只是为了澄清任何人读这个，MySqlExcelBuilder.class.php不是PHPExcel的一部分（否则我会被问起它在PHPExcel库中的人问questiosn） – 2012-07-18 19:24:18

问题解决！我打电话错误的数据库，菜鸟的错误。
