我有一个包含2个表的数据库
用户
专业化
我编写了这两个查询，首先从用户表中相同的特化表中选择specialization_id
在第二个查询中 我需要在用户表中插入specialization_id作为专业化表的外键但我收到错误资源ID＃7
$query_select_spec = mysql_query("SELECT specialization_name FROM specialization, user WHERE user.specialization_id = specialization.specialization_id")or die(mysql_error());

答案 0 :(得分：4)
这不是错误，它是mysql_query返回的内容 要获取值，您应该遍历mysql结果
while($row = mysql_fetch_assoc($query))
print_r($row);
答案 1 :(得分：0)
query1 =您在用户字段中没有specilization_id。你正在使用它-user.specialization_id
在第二个查询中尝试user而不是用户，因为它可能是关键字。
答案 2 :(得分：0)
$query_select_spec = mysql_query("SELECT specialization_name FROM specialization, user WHERE user.specialization_id = specialization.specialization_id")or die(mysql_error());
$row_select_spec = mysql_fetch_assoc ($query_select_spec);
$specialization = $row_select_spec['specialization_name'];
$query = mysql_query("INSERT INTO user(user_name, first_name, last_name, address, district_name, village_name, birth_date, email_address, specialization_name, password, registered_date)VALUES('$username', '$fname', '$lname', '$country', '$district', '$village', '$bdate', '$email', '$specialization', '$pass1', now())") or die("could not insert data");
答案 3 :(得分：0)
首先，我建议你不要使用旧的和过时的mysql扩展，而是升级到mysqli或PDO扩展。你有什么没有错误，你只需要循环结果。
我会这样使用mysqli扩展名。
//Connect to the db using the mysql improved extension
$mysqli = new mysqli("localhost", "user", "password", "database");
if ($mysqli->connect_errno) {
echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}
//Select spec
$query = "SELECT specialization_name FROM specialization, user WHERE user.specialization_id = specialization.specialization_id";
$result = $mysqli->query($query);
//Print results
while($data = $result->fetch_assoc()){
echo'<pre>'; // Format your dump as code
var_dump($data);
}
