MySQl错误＃1064语法错误

Question

我收到此错误：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 4 SQL=SELECT company.contactname AS name, company.contactemail AS email, job.title, job.sendemail FROM `kecobo_js_job_companies` AS company JOIN `kecobo_js_job_jobs` AS job ON job.companyid = company.id WHERE job.id =

使用此查询：

$jobquery = "SELECT company.contactname AS name, company.contactemail AS email, job.title, job.sendemail 
            FROM `#__js_job_companies` AS company
            JOIN `#__js_job_jobs` AS job ON job.companyid = company.id  
            WHERE job.id = ".$jobid;

是否有人建议可能出现的问题？

Answer 1

$jobquery = "SELECT company.contactname AS name, company.contactemail AS email, job.title, job.sendemail 
            FROM `#__js_job_companies` AS company
            JOIN `#__js_job_jobs` AS job ON job.companyid = company.id  
            WHERE job.id = '".$jobid."'";

考虑注射剂量

Answer 2

考虑使用MySQLi或PDO。至于您的问题$jobid是空的，您可以在查询中以等号结尾查看。
