我使用以下PHP脚本创建了一个临时表
WebRequest
然后我尝试使用以下脚本
将数据插入此表$query = "CREATE TEMPORARY TABLE people(id int(11) not null auto_increment, first_name varchar(25), second_name varchar(25), primary key(id))";
$q=$pdo->prepare($query);
$q->execute();
我想要插入的数据来自另一个表。起初这似乎是一个由基本错误引起的问题,但我无法弄清楚问题出在哪里,因为当我运行这个脚本时(见下文),我看到所有字段都已创建
$query2 = "INSERT INTO people(first_name, second_name) VALUES(:firstname,:secondname)";
$q2=$pdo->prepare($query2);
$q2->bindValue(':firstname', $firstname,PDO::PARAM_STR);
$q2->bindValue(':secondname', $secondname,PDO::PARAM_STR);
$q2->execute;
答案 0 :(得分:1)
$query2 = "INSERT INTO people(first_name, second_name) VALUES(:firstname,:secondname)";
$q2=$pdo->prepare($query2);
$q2->bindValue(':firstname', $firstname,PDO::PARAM_STR);
$q2->bindValue(':secondname', $secondname,PDO::PARAM_STR);
$q2->execute;
缺少()
方法的execute()
。
Additionaly:
如果你试图从另一个表填充表,没有其他步骤,你可以直接通过mysql执行此操作:
$query2 = "INSERT INTO people(first_name, second_name)
select firstname, secondname from otherTABLE where something = 'xy'";
$pdo->exec($query2);
直接在数据库中执行此操作可以减少php尝试执行此操作时出错的可能性。
你的脚本的其余部分是正确的,我在本地进行了测试:
$pdo = new PDO('mysql:dbname=test;host=127.0.0.1', 'root', '', array(PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC));
$query = "CREATE TEMPORARY TABLE people(id int(11) not null auto_increment, first_name varchar(25), second_name varchar(25), primary key(id))";
$q = $pdo->prepare($query);
$q->execute();
$firstname = 'test';
$secondname = 'what';
$query2 = "INSERT INTO people(first_name, second_name) VALUES(:firstname,:secondname)";
$q2 = $pdo->prepare($query2);
$q2->bindValue(':firstname', $firstname, PDO::PARAM_STR);
$q2->bindValue(':secondname', $secondname, PDO::PARAM_STR);
$q2->execute();
$pdo->exec("INSERT INTO people(first_name, second_name) SELECT 'prename', 'surname'");
$result = $pdo->query('SELECT * FROM people');
echo '<pre>';
var_dump($result->fetchAll());
exit;
显示:
array(2) {
[0]=>
array(3) {
["id"]=>
string(1) "1"
["first_name"]=>
string(4) "test"
["second_name"]=>
string(4) "what"
}
[1]=>
array(3) {
["id"]=>
string(1) "2"
["first_name"]=>
string(7) "prename"
["second_name"]=>
string(7) "surname"
}
}
