Java與各種數據庫連接代碼

6、MySQL數據庫
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
String url ="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1"
//myDB為數據庫名
Connection conn= DriverManager.getConnection(url);

8.Oracle8/8i/9i數據庫（thin模式）
//import java.sql.*;
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String url="jdbc:oracle:thin:@localhost:1521:orcl"; //orcl為數據庫的SID
String user="test";
String password="test";
Connection conn= DriverManager.getConnection(url,user,password); 
Statement stmtNew=conn.createStatement();

3、Sql Server7.0/2000數據庫
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb";
//mydb為數據庫
String user="sa";
String password="";
Connection conn= DriverManager.getConnection(url,user,password);

 

1、Oracle8/8i/9i數據庫（thin模式）
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String url="jdbc:oracle:thin:@localhost:1521:orcl";
//orcl為數據庫的SID
String user="test";
String password="test";
Connection conn= DriverManager.getConnection(url,user,password);

18.連接Excel文件
//import java.sql.*;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url = "jdbc:odbc:driver={Microsoft Excel Driver (*.xls)};DBQ=D:\\myDB.xls"; // 不設置數據源
String user="myuser";
String password="mypassword";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmtNew=conn.createStatement();

2、DB2數據庫
Class.forName("com.ibm.db2.jdbc.app.DB2Driver ").newInstance();
String url="jdbc:db2://localhost:5000/sample";
//sample為你的數據庫名
String user="admin";
String password="";
Connection conn= DriverManager.getConnection(url,user,password);

 

4、Sybase數據庫
Class.forName("com.sybase.jdbc.SybDriver").newInstance();
String url =" jdbc:sybase:Tds:localhost:5007/myDB";
//myDB為你的數據庫名
Properties sysProps = System.getProperties();
SysProps.put("user","userid");
SysProps.put("password","user_password");
Connection conn= DriverManager.getConnection(url, SysProps);

5、Informix數據庫
Class.forName("com.informix.jdbc.IfxDriver").newInstance();
String url =
"jdbc:informix-sqli://123.45.67.89:1533/myDB:INFORMIXSERVER=myserver;
user=testuser;password=testpassword";
//myDB為數據庫名
Connection conn= DriverManager.getConnection(url);

 

7、PostgreSQL數據庫
Class.forName("org.postgresql.Driver").newInstance();
String url ="jdbc:postgresql://localhost/myDB"
//myDB為數據庫名
String user="myuser";
String password="mypassword";
Connection conn= DriverManager.getConnection(url,user,password);
 
8、JDBC-ODBC橋
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection("jdbc:odbc:jsp");
jsp為建立的odbc數據源名，事先要先將SQL server的表設置為數據源。在“管理工具”-“數據源odbc”里用系統DNS添加。

 

 

9.DB2數據庫
//import java.sql.*;
Class.forName("com.ibm.db2.jdbc.app.DB2Driver ").newInstance();
String url="jdbc:db2://localhost:5000/sample"; //sample為你的數據庫名
String user="admin";
String password="";
Connection conn= DriverManager.getConnection(url,user,password); 
Statement stmtNew=conn.createStatement();

10.Sql Server7.0/2000數據庫
//import java.sql.*;
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
//String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=db2"; //7.0、2000
String url="jdbc:sqlserver://localhost:1433;DatabaseName=db2"; //2005
//db2為數據庫名
String user="sa";
String password="";
Connection conn= DriverManager.getConnection(url,user,password); 
Statement stmtNew=conn.createStatement();

11.Sybase數據庫
//import java.sql.*;
Class.forName("com.sybase.jdbc.SybDriver").newInstance();
String url =" jdbc:sybase:Tds:localhost:5007/myDB";//myDB為你的數據庫名
Properties sysProps = System.getProperties();
SysProps.put("user","userid");
SysProps.put("password","user_password");
Connection conn= DriverManager.getConnection(url, SysProps); 
Statement stmtNew=conn.createStatement();

12.Informix數據庫
//import java.sql.*;
Class.forName("com.informix.jdbc.IfxDriver").newInstance();
String url = "jdbc:informix-sqli://123.45.67.89:1533/myDB:INFORMIXSERVER=myserver;
user=testuser;password=testpassword"; //myDB為數據庫名
Connection conn= DriverManager.getConnection(url); 
Statement stmtNew=conn.createStatement();

13.MySQL數據庫
//import java.sql.*;
//Class.forName("org.gjt.mm.mysql.Driver").newInstance();
Class.forName("com.mysql.jdbc.Driver");
//String url ="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1";
String url ="jdbc:mysql://localhost:3306/myDB";

//myDB為數據庫名
Connection conn= DriverManager.getConnection(url,"root","root"); 
Statement stmtNew=conn.createStatement();

14.PostgreSQL數據庫
//import java.sql.*;
Class.forName("org.postgresql.Driver").newInstance();
String url ="jdbc:postgresql://localhost/myDB" //myDB為數據庫名
String user="myuser";
String password="mypassword";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmtNew=conn.createStatement();

15.access數據庫直連用ODBC的
//import java.sql.*;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") ;
String url="jdbc:odbc:Driver={MicroSoft Access Driver (*.mdb)};DBQ="+application.getRealPath("/Data/ReportDemo.mdb");
Connection conn = DriverManager.getConnection(url,"sa","");
Statement stmtNew=conn.createStatement();

16.程序計時
long time1=System.currentTimeMillis();
long time2=System.currentTimeMillis();
long interval=time2-time1;

17.延時
try {
Thread.sleep(Integer.Parse(%%1));
} catch(InterruptedException e) {
e.printStackTrace();
}
