MySQL 创建新表时出现语法错误

Question

I have been trying for hours to solve this issue, I have searched for the answers here and still can't figure it out what wrong with my code. I'm trying to create a new database and a table with PHP and MySQL:

<?php
$hostname = 'localhost';
$username = 'root';
$password = '';

$connectDB = mysqli_connect($hostname, $username, $password);
if (!$connectDB) {
    die('Connection failed: ' . mysqli_connect_error());
}

$query = 'CREATE DATABASE user_records
    CREATE TABLE records_list (
    id INT(5) NOT NULL PRIMARY KEY AUTO_INCREMENT,
    username VARCHAR(30) NOT NULL UNIQUE,
    userpass VARCHAR(30) NOT NULL)';

if (mysqli_query($connectDB, $query)) {
    echo '<div class="alertSuccess"><span>Query successful</span></div>';
} else {
    echo '<div class="alertError"><span>Query failed: <i>' . mysqli_error($connectDB) . '</i></span></div>';
}

?>

And here's the error:

Query failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'CREATE TABLE records_list ( id INT(5) NOT NULL PRIMARY KEY AUTO_INCREME' at line 2

I'm using VSCode and XAMPP, latest MySQL 8.

Update: I have edited my code as @Phil and @Mark Walker suggested:

$queryCrDB = "CREATE DATABASE user_records;";
    
$queryCrTb = "USE user_records;
CREATE TABLE records_list (
id INT(5) NOT NULL PRIMARY KEY AUTO_INCREMENT,
username VARCHAR(30) NOT NULL UNIQUE,
userpass VARCHAR(30) NOT NULL);";

if (mysqli_query($connectDB, $queryCrDB)) {
    echo '<div class="alertSuccess"><span>Query successful</span></div>';
} else {
    echo '<div class="alertError"><span>Query failed: <i>' . mysqli_error($connectDB) . '</i></span></div>';
}
if (mysqli_query($connectDB, $queryCrTb)) {
    echo '<div class="alertSuccess"><span>Query successful</span></div>';
} else {
    echo '<div class="alertError"><span>Query failed: <i>' . mysqli_error($connectDB) . '</i></span></div>';

But it still gives me syntax error at CREATE TABLE line.

Answer 1

You need to run the create database before the create table. Query below should work, note the semi-colons closing individual commands and the "USE database" to switch into the newly created db.

CREATE DATABASE user_records;
USE user_records;
CREATE TABLE records_list (
    id INT(5) NOT NULL PRIMARY KEY AUTO_INCREMENT,
    username VARCHAR(30) NOT NULL UNIQUE,
    userpass VARCHAR(30) NOT NULL);

Answer 2

Based on mysql 8 doc , it should be:

id INT(5) NOT NULL AUTO_INCREMENT PRIMARY KEY 

not

id INT(5) NOT NULL PRIMARY KEY AUTO_INCREMENT

PRIMARY KEY and AUTO_INCREMENT are reversed
