是否可以在一个SQL查询中放入两个INSERT语句

Question

I'm trying to get two INSERT statement into one SQL query. I tried several things but nothing seems to work. If I look on the internet it seems it has to work. But it doesn't work for me and I get an error. I'm using this code with PDO.

I tried multiple web browsers, multiple types of code and I tried the "BEGIN" and "COMMIT" statement.

$sql = "INSERT INTO gebruiker (email, wachtwoord, rol_id) VALUES (?, ?, 2); ".
"INSERT INTO huisarts (voornaam, achternaam, email, straatnaam, huisnummer, postcode, plaats, telefoonnummer, uid, rol_id) VALUES (?, ?, ?, ?, ?, ?, ?, ?, LAST_INSERT_ID(), 2);";
$pdostatement = $pdo->prepare($sql);

Answer 1

That silly concatenation mistake aside, it is technically possible to run two INSERT queries in one call, but there is not a single reason to do so .

Besides, you will need to configure PDO specifically to allow multiple queries which is not advised.

Therefore, just run these two queries as two separate prepared statements.

$sql = "INSERT INTO gebruiker (email, wachtwoord, rol_id) VALUES (?, ?, 2)";
$stmt = $pdo->prepare($sql);
$stmt->execute($first_query_data);
$sql = "INSERT INTO huisarts (voornaam, achternaam, email, straatnaam, huisnummer, postcode, plaats, telefoonnummer, uid, rol_id) 
VALUES (?, ?, ?, ?, ?, ?, ?, ?, LAST_INSERT_ID(), 2);";
$stmt = $pdo->prepare($sql);
$stmt->execute($second_query_data);
