php - 'customer' 中的未知列 'on clause'

Question

我的公司有一个发票脚本，我现在对 PHP 有一点了解(尤其是操作现有文件)，并且该脚本的程序员不再可用，因此我决定使用报价列表来扩展该脚本。这与发票脚本的工作方式完全相同，只是它使用不同的表。

现在我收到错误:

A Database Error Occurred
Error Number: 1054
Unknown column 'customer' in 'on clause'

SELECT idofferte,noofferte,CONCAT(namecustomer,' ',lastname)
     customer,DATE_FORMAT(dateofferte,'%d/%m/%Y')dateofferte,
     (SELECT SUM(pu*duration)
         FROM service2
         WHERE offerte=idofferte
      ) subtotal,discount,btw,transport,material
FROM offerte
INNER JOIN customer ON idcustomer=customer
WHERE 1=1
ORDER BY CAST(SUBSTR(noofferte,9) AS UNSIGNED) DESC
LIMIT 0,25 

原始脚本(用于发票):

function ilist( $start = 0, $limit = 25, $pattern = '' ) {
    $where = 'WHERE 1=1';
    if( '' != $pattern )
        $where .= " AND namecustomer LIKE '$pattern%' OR lastname LIKE '$pattern%'";
    return $this->db->query( "SELECT idinvoice,noinvoice,CONCAT(namecustomer,' ',lastname) customer,DATE_FORMAT(dateinvoice,'%d/%m/%Y')dateinvoice,(SELECT SUM(pu*duration) FROM service WHERE invoice=idinvoice)subtotal,discount,btw,transport,material FROM invoice INNER JOIN customer ON idcustomer=customer $where ORDER BY CAST(SUBSTR(noinvoice,9) AS UNSIGNED) DESC LIMIT $start,$limit" )->result_array();
} 

我的脚本(用于优惠):

function ilist( $start = 0, $limit = 25, $pattern = '' ) {
    $where = 'WHERE 1=1';
    if( '' != $pattern )
        $where .= " AND namecustomer LIKE '$pattern%' OR lastname LIKE '$pattern%'";
    return $this->db->query( "SELECT idofferte,noofferte,CONCAT(namecustomer,' ',lastname) customer,DATE_FORMAT(dateofferte,'%d/%m/%Y')dateofferte,(SELECT SUM(pu*duration) FROM service2 WHERE offerte=idofferte)subtotal,discount,btw,transport,material FROM offerte INNER JOIN customer ON idcustomer=customer $where ORDER BY CAST(SUBSTR(noofferte,9) AS UNSIGNED) DESC LIMIT $start,$limit" )->result_array();
} 

我的脚本和原始脚本之间的区别在于表格。 我该如何解决这个错误？

注意:该错误当然不会出现在原始脚本中。

提前致谢!

遇到问题了。 我刚刚意识到我在数据库中犯了一个错字。 我写为列名:Costumer 而不是 customer。

感谢大家的帮助!
