#1

To answer you question: creating a table is executing a SQL statement against the server.

回答你的问题：创建一个表正在对服务器执行一条SQL语句。

You should rethink your strategy, creating a table based on user input is bad design.

你应该重新考虑你的策略，根据用户输入创建一个表是糟糕的设计。

#2

Use the 'CREATE TABLE' syntax in your query.

在查询中使用“CREATE TABLE”语法。
