Question

我尝试使用CREATE TABLE IF NOT EXISTS创建一个表但出错了。我无法解决这个问题。谁能帮助我？

<?php
$server     = "localhost";
$user       = "root";
$password   = "";
$dbname     = "bombus";
$connection = @new mysqli( $server, $user, $password, $dbname ) or die( "ERROR : " . mysqli_error() );
$tablename  = "users";
$newTable   = $connection->query("CREATE TABLE IF NOT EXISTS $tablename(
  ID int NOT NULL AUTO_INCREMENT,
  PRIMARY KEY(ID),
  userName VARCHAR(MAX) NOT NULL UNIQUE,
  password CHAR(32) NOT NULL,
  isAdmin TINYINT(1) NOT NULL,
  companyID int NOT NULL,
  branchID int NOT NULL
)");
mysqli_close($connection);
?>

感谢您的帮助。

您的脚本中存在一些问题。更改您的创建表查询，如下所示：

$newTable   = $connection->query("CREATE TABLE IF NOT EXISTS $tablename(
  ID int NOT NULL AUTO_INCREMENT,
  PRIMARY KEY(ID),
  userName VARCHAR(50) NOT NULL UNIQUE,
  user_password CHAR(32) NOT NULL,
  isAdmin TINYINT(1) NOT NULL,
  companyID int NOT NULL,
  branchID int NOT NULL)");
