嘿伙计们我想在 php 中查询一些东西但是 WHERE 是数组的索引这就是我所做的
$data=array();
while ($row = mysql_fetch_array($result))
{
$item = array(
'sec_id'=>$row['section_id'],
'sec_name'=>$row['section_name'],
'sec_dept'=>$row['section_department'],
'sec_lvl'=>$row['section_level'],
'advisory_id'=>$row['advisory_id'],
'first_name'=>$row['f_firstname'],
'last_name'=>$row['f_lastname'],
'middle_name'=>$row['f_middlename'],
'advisor_id'=>$row['faculty_id'],
);
$get_subjects = "SELECT subject_name
FROM subjects
WHERE level = '".$row['section_level']."' ";
$result_get_subjects =mysql_query($get_subjects)or die(mysql_error());
$subjects_count = mysql_num_rows($result_get_subjects);
$check_archive_subjects = " SELECT b.subject_name
FROM registrar_grade_archive a
LEFT JOIN subjects b ON(a.subject_id=b.subject_id)
LEFT JOIN section c ON(a.section_id = c.section_id)
WHERE a.advisor_faculty_id ='".$row['faculty_id']."'
WHERE a.section_id ='".$row['section_id']."'
GROUP BY b.subject_name ASC
" ;
$query_checking =mysql_query($check_archive_subjects)or die(mysql_error());
$subjects_count_sent = mysql_num_rows($query_checking);
但不幸的是,我在 $check_archive_subjects 中收到一个错误:
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 'WHERE a.section_id ='24'
有没有其他方法可以在 mysql 的 where 子句中放置数组索引。我知道 mysql 已被弃用,在我完成这个项目后我将切换到 mysqli,所以请原谅我。提前致谢
最佳答案
多个 WHERE
条件应该使用 bool 关键字 AND
或 OR
连接。您不会发出多个 WHERE
子句。
此外,请阅读有关 MySQL 扩展的内容 - https://stackoverflow.com/a/12860046/283366
关于php - 如果 where 等于数组索引,则在 php mysql 中选择 where,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/14544922/
