Question

我有一个给我的查询。我想使用php脚本执行此操作，单击按钮并将其插入另一个表。

以下是查询：

SELECT students.student_id,GROUP_CONCAT(teachers.teacher_name) FROM
students JOIN teachers ON teachers.subject_teaches =
students.subject_enrolled GROUP BY students.student_id

我有一个脚本，显示它的内容并且它正在工作。我所要做的就是将它插入另一个表。我该怎么做？

      <?php
            mysql_connect("localhost","root");
            mysql_select_db("join");
            $res=mysql_query("SELECT students.student_id, GROUP_CONCAT(teachers.teacher_name)FROM students
                              JOIN teachers ON teachers.subject_teaches = students.subject_enrolled
                              GROUP BY students.student_id");
            while($row=mysql_fetch_array($res))
            {
      ?>
        <tr>
         <td><?php echo $row['GROUP_CONCAT(teachers.teacher_name)'];?></td><br>
        </tr>

       <?php
             }
       ?>

如果您真的只想将结果集的数据插入到另一个表中，则只需使用：http://dev.mysql.com/doc/refman/5.7/en/insert-select.html

querysyntax：

INSERT INTO insertTable (columnsOfTable) SELECT columnsToInsert FROM selectTable;

在你的情况下：

$res = mysql_query("INSERT INTO yourtable (columnStudent_id, columnTeachernames) SELECT students.student_id, GROUP_CONCAT(teachers.teacher_name)FROM students
                  JOIN teachers ON teachers.subject_teaches = students.subject_enrolled
                  GROUP BY students.student_id");

使用PHP脚本连接表
