我正在尝试将我的java项目连接到数据库。我正在创建一个方法来使用以下代码创建表

package DataBaseConnectivity;

import java.sql.Connection;
import java.sql.Driver;
import java.sql.DriverManager;
import java.sql.Statement;
import java.util.Scanner;

public class DataBaseConnectivity {
    public static void main(String args[]) {

        // Creating the connection using Oracle DB
        // Note: url syntax is standard, so do grasp
        String url = "jdbc:sqlserver://localhost:1433;databaseName=SchoolMgt;encrypt=true;trustServerCertificate=true";

        // Username and password to access DB
        // Custom initialization
        String user = "sa";
        String pass = "root";

        // Entering the data

        Scanner scanner = new Scanner(System.in);

        String tableCreationsql = " create table  Students ( id integer PRIMARY KEY,fname VARCHAR (8),birthdate date,lname VARCHAR (8))";

        Connection con = null;

        // Try block to check for exceptions
        try {

            Driver driver = (Driver) Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
            // Registering drivers
            DriverManager.registerDriver(driver);

            // Reference to connection interface
            con = DriverManager.getConnection(url, user, pass);

            // Creating a statement
            Statement st = con.createStatement();

            // Executing query
            int Executing = st.executeUpdate(tableCreationsql);
            if (Executing >= 1) {
                System.out.println("Created Successfully : " + tableCreationsql);
            } else {
                System.out.println("Creation Is Failed");
            }
            // Closing the connections
            con.close();
        }

        // Catch block to handle exceptions
        catch (Exception ex) {
            // Display message when exceptions occurs
            System.err.println(ex);
        }
    }

}

代码工作正常，但它从不输入if条件，而是直接转到else。此外，即使转到else，也会创建一些表
我希望创建成功，并应在数据库中创建表。
