Question

我尝试在表中进行简单的插入，但是我收到以下错误： SQLSTATE [HY093]：参数编号无效：参数未定义。我知道如果没有参数和匹配不相同，这个错误就会消失，但我一遍又一遍地检查它，我无法找到任何这样的不匹配。

我有表中的列数：16 参数编号：16 没有比赛：16

表格说明：

请帮我弄清楚错误。我现在已经上了几个小时了。我知道这可能是我无法发现的愚蠢行为。如果您需要更多详细信息，请与我们联系。

Answer 1

你有：ftyr，：ftmth 在您的查询中但设置

$stmt -> bindParam(':f_tyr', $f_tExp_yr, PDO::PARAM_INT);
$stmt -> bindParam(':f_tmth', $f_tExp_mth, PDO::PARAM_INT);

代码。

这导致这些参数没有价值。

Answer 2

您在声明中: param之前忘记了f_iyr。

        $query = "insert into faculty (faculty_id , faculty_name , department_id , department_name ,profile_pic , designation , doj , email , highest_qualification , industrial_exp_yr ,industrial_exp_month , teaching_exp_yr , teaching_exp_month ,
area_of_interest , national_pub , international_pub)  values (:facul_id , :f_name , :dept_id , :dept_name , :f_pic , :f_designation , :f_doj , :f_email , :f_qualification , :f_iyr ,:f_imth , :ftyr , :ftmth , :finterest , :flpub , :fipub);";

另外:ftyr，:ftmth未设置

SQLSTATE [HY093]：参数号无效：未定义参数 - 尽管未找到不匹配
