java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
import org.junit.Test;
public class Demo1 {
private String url = "jdbc:mysql://localhost:3306/tableName"
;
private String user = "root"
;
private String password = "root"
;
@Test
public void test1(){
Connection conn =
null;
Statement stmt =
null;
try{
//1、注册驱动
Class.forName("com.mysql.jdbc.Driver"
);
//2、创建连接对象
conn =
DriverManager.getConnection(url, user, password);
//3、创建Statement对象
stmt =
conn.createStatement();
//4、准备sql语句
String sql = "CREATE TRABLE student(id PRIMARY KEY AUTO_INCREMENT,name VARCHAR(20), gender(2))"
;
//5、发送sql语句、执行sql语句
int count =
stmt.executeUpdate(sql);
//5、输出
System.out.println("影响了" + count + "行!"
);
}catch(Exception e){
e.printStackTrace();
throw new RuntimeException(e);
}finally{
//7、关闭连接(顺序:后打开的先关闭)
if(stmt !=
null){
try {
stmt.close();
} catch (SQLException e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
if(conn !=
null){
try {
conn.close();
} catch (SQLException e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
