"이 토큰을 삭제, 토큰에 구문 오류"와 같은 URL을 연결 아래에 오류가 발생하고 java.Is이

Answer 1

연결 URL의 일반적인 형태는 (MS SQL Server 용)입니다

jdbc:sqlserver://[serverName[\instanceName][:portNumber]][;property=value[;property=value]] 

exampl 문자열 URL을 작성하는 올바른 방법 전자, 연결 URL의

jdbc:sqlserver://localhost;user=MyUserName;password=*****; 

일반적인 형태는 다음

jdbc:mysql://hostname/ databaseName 

, 호스트 이름,

예 (그 필수) PORTNUMBER를 포함해야합니다 (MySQL 서버에 대한)입니다

//STEP 1. Import required packages 
import java.sql.*; 

public class JDBCExample { 
    // JDBC driver name and database URL 
    static final String JDBC_DRIVER = "com.mysql.jdbc.Driver"; 
    static final String DB_URL = "jdbc:mysql://localhost:3306/STUDENTS"; 

    // Database credentials 
    static final String USER = "username"; 
    static final String PASS = "password"; 

    public static void main(String[] args) { 
    Connection conn = null; 
    Statement stmt = null; 
    try{ 
     //STEP 2: Register JDBC driver 
     Class.forName("com.mysql.jdbc.Driver"); 

     //STEP 3: Open a connection 
     System.out.println("Connecting to a selected database..."); 
     conn = DriverManager.getConnection(DB_URL, USER, PASS); 
     System.out.println("Connected database successfully..."); 

     //STEP 4: Execute a query 

    }catch(SQLException se){ 
     //Handle errors for JDBC 
     se.printStackTrace(); 
    }finally{ 
    conn.close(); 
    }//end finally 
    System.out.println("Goodbye!"); 
} 
}
