Answer 1

你的代码是：

DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());

重写上面的代码如下，它应该可以工作

Class.forName("oracle.jdbc.driver.OracleDriver");

Answer 2

要运行非查询，您需要使用执行

statement.execute("UPDATE ...")
statement.execute("INSERT ...")
statement.execute("DELETE ...")

您可以在此处查看该方法的签名：java.sql.Statement.execute
