“ on子句”中的未知列“ customer”

Question

我有一家公司的发票脚本，现在我对PHP有一点了解（尤其是处理现有文件），并且该脚本的程序员不再可用，因此我决定使用要约列表扩展该脚本。 它的工作原理与发票脚本完全相同，只是使用了不同的表。

现在我得到了错误：

发生数据库错误
错误编号：1054
“ on子句”中的未知列“ customer”

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（要约）：

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：该错误不会出现在课程的原始脚本中。

提前致谢！

Answer 1

有问题了。 我刚刚意识到我在数据库中打错了字。 我写为列名：Costumer而不是客户。

谢谢大家的帮助！
