JDBC连接各种数据库的方法
1)连接Oracle 8/8i/9i/10g/11g(thin模式)
Class.forName("oracle.JDBC.driver.OracleDriver").newInstance();
String url="JDBC:oracle:thin:@localhost:1521:orcl" //orcl为Oracle数据库的SID
String user="test";
String password="test";
Connection con=DriverManager.getConnection(url,user,password);
2)连接DB2数据库
Class.forName("com.ibm.db2.jcc.DB2Driver");
String url="JDBC:db2://localhost:5000/testDb";/**数据库连接串**/
String user="test"; String password="test";
Connection con=DriverManager.getConnection(url,user,password);
3)连接MySQL数据库
Class.forName("com.mysql.jdbc.Driver");
String url="JDBC:mysql://localhost:8080/testDB";
String user="test"; String password="test";
Connection con=DriverManager.getConnection(url,user,password);
4)连接SQL Server数据库
Class.forName("com.microsoft.JDBC.sqlserver.SQLServerDriver");
String url="JDBC:microsoft:sqlserver://localhost:1433;DatabaseName=testDb";
String user="test"; String password="test";
Connection con=DriverManager.getConnection(url,user,password);
5)连接PostgreSQL数据库
Class.forName("org.postgresql.Driver");
String url="JDBC:postgresql://localhost/testDb";
String user="test"; String password="test";
Connection con=DriverManager.getConnection(url,user,password);
6)连接Access数据库
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url="JDBC:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ="+application.getRealPath("/Data/testDb/mdb");
Connection conn=DriverManager.getConnection(url,"","");
7连接Sybase数据库
Class.forName("com.sybase.JDBC.SybDriver");
String url="JDBC:sybase:Tds:localhost:5007/testDb";
Properties pro=System.getProperties();
pro.put("user","userId");
pro.put("password","user_password");
Connection con=DriverManager.getConnection(url,pro);
8连接informix数据库
Class.forName("com.informix.JDBC.ifxDriver");
String url="JDBC:informix-sqli:localhost:1533/testDb:INFORMIXSERVER=myserver"user=testUser;password=testpassword"; Connection con=DriverManager.getConnection(url);
示例:我这里有个大牛聚集地,前面九七三中间打四五四后面两个零,组合起来就行了。连接SQL Server2008R2数据库
首先Build Path → 添加外部sqljdbc.jar驱动
import java.sql.*;
public class DB {
public static void main(String[] args) throws Exception {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection("jdbc:sqlserver://localhost:1433; DatabaseName=数据库名", "sa", "1234");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select * from 表名");
while(rs.next()) {
System.out.println("id为:" + rs.getString("id") + "name为:" + rs.getString("name"));
}
System.out.println("数据库连接成功!");
rs.close();
stmt.close();
conn.close();
System.out.println("数据库成功关闭!");
}
}
