Question

所以现在这是我的代码：

$mysqli = new mysqli("localhost", "username", "password", "dbname"); // connect

        if (mysqli_connect_errno()) { // checking connection
            printf("Connect failed: %s\n", mysqli_connect_error());
            exit();
        }

因此，此数据库中有几个表。我想显示所有表的所有名称。我已经在互联网上搜索了一段时间，但我无法找到正确的答案。提前谢谢！

Answer 1

您想要的SQL语句是：

SHOW TABLES;

Answer 2

您可以在PHP代码中使用这些查询：

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| begueradj          |
| mysql              |
| performance_schema |
| phpmyadmin         |
| tester             |
+--------------------+
6 rows in set (0.04 sec)

mysql> use tester;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> show tables;
+------------------+
| Tables_in_tester |
+------------------+
| images           |
+------------------+
1 row in set (0.00 sec)
