根据ID从多个表中获取数据

Question

我在mysql db中有一个2表。我想从这两个表中获取所有数据。表名如下：

1. tutor_signup_form
2. tutor_signup_edu_psle

因此我正在使用以下sql查询但无法获得结果。

$tutor_id =  (int) $_GET['tutor_id'];

$query =  mysql_query("SELECT  tutor_signup_form . *, tutor_signup_edu_psle . * FROM 
tutor_signup_form INNET JOIN tutor_signup_edu_psle ON tutor_signup_form.tutor_id = '$tutor_id'");
$result =  mysql_fetch_array($query);

注意：两个表都有相同的tutor_id列。

3表的新更新：

$query =  mysql_query("SELECT tutor_signup_form . *, tutor_signup_edu_psle . *,   
tutor_signup_edu_olevel . * FROM tutor_signup_form

INNER JOIN tutor_signup_edu_psle ON tutor_signup_form.tutor_id = tutor_signup_form.tutor_id , 

INNER JOIN tutor_signup_edu_olevel ON  tutor_signup_form.tutor_id =  
tutor_signup_edu_olevel.tutor_id 

where tutor_signup_form.tutor_id = '$tutor_id' ");

$result =  mysql_fetch_array($query);

Answer 1

试试这个

SELECT  * FROM 
tutor_signup_form  ts1 INNER JOIN 
tutor_signup_edu_psle  ts2 ON ts1.tutor_id = ts2.tutor_id
and ts1.tutor_id='$tutor_id'

Answer 2

您的SQL查询应该是这样的，您也可以使用表名的别名

 $query =  mysql_query("SELECT tf.*, te.* FROM tutor_signup_form AS tf INNER JOIN tutor_signup_edu_psle AS te ON tf.tutor_id = te.tutor_id WHERE tf.tutor_id = '$tutor_id'");

这可能对你有用

Answer 3

在ON中你不能给$ tutor_id你需要给其他表格列参考如

ON tutor_signup_form.tutor_id = tutor_signup_form.tutor_id 

并在where子句中提供$ tutor_id的过滤器。所以你的查询看起来像

$query =  mysql_query("SELECT  tutor_signup_form . *, tutor_signup_edu_psle . * FROM 
tutor_signup_form INNER JOIN tutor_signup_edu_psle ON tutor_signup_form.tutor_id = tutor_signup_form.tutor_id where tutor_signup_form.tutor_id = '$tutor_id'");

此外，我发现你拼错了INNER JOIN到INNET JOIN。
