Java与各种数据库连接代码

 1、Oracle8/8i/9i数据库（thin模式）Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();String url="jdbc:oracle:thin:@localhost:1521:orcl";//orcl为数据库的SIDString user="test";String password="test";Connection conn= DriverManager.getConnection(url,user,password);2、DB2数据库Class.forName("com.ibm.db2.jdbc.app.DB2Driver ").newInstance();String url="jdbc:db2://localhost:5000/sample";//sample为你的数据库名String user="admin";String password="";Connection conn= DriverManager.getConnection(url,user,password);3、Sql Server7.0/2000数据库Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb";//mydb为数据库String user="sa";String password="";Connection conn= DriverManager.getConnection(url,user,password);4、Sybase数据库Class.forName("com.sybase.jdbc.SybDriver").newInstance();String url =" jdbc:sybase:Tds:localhost:5007/myDB";//myDB为你的数据库名Properties sysProps = System.getProperties();SysProps.put("user","userid");SysProps.put("password","user_password");Connection conn= DriverManager.getConnection(url, SysProps);5、Informix数据库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为数据库名Connection conn= DriverManager.getConnection(url);6、MySQL数据库Class.forName("org.gjt.mm.mysql.Driver").newInstance();String url ="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1"//myDB为数据库名Connection conn= DriverManager.getConnection(url);7、PostgreSQL数据库Class.forName("org.postgresql.Driver").newInstance();String url ="jdbc:postgresql://localhost/myDB"//myDB为数据库名String user="myuser";String password="mypassword";Connection conn= DriverManager.getConnection(url,user,password); 8、JDBC-ODBC桥Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");Connection con=DriverManager.getConnection("jdbc:odbc:jsp");jsp为建立的odbc数据源名，事先要先将SQL server的表设置为数据源。在“管理工具”-“数据源odbc”里用系统DNS添加。 8.Oracle8/8i/9i数据库（thin模式）//import java.sql.*;Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();String url="jdbc:oracle:thin:@localhost:1521:orcl"; //orcl为数据库的SIDString user="test";String password="test";Connection conn= DriverManager.getConnection(url,user,password); Statement stmtNew=conn.createStatement();9.DB2数据库//import java.sql.*;Class.forName("com.ibm.db2.jdbc.app.DB2Driver ").newInstance();String url="jdbc:db2://localhost:5000/sample"; //sample为你的数据库名String user="admin";String password="";Connection conn= DriverManager.getConnection(url,user,password); Statement stmtNew=conn.createStatement();10.Sql Server7.0/2000数据库//import java.sql.*;Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();//String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=db2"; //7.0、2000String url="jdbc:sqlserver://localhost:1433;DatabaseName=db2"; //2005//db2为数据库名String user="sa";String password="";Connection conn= DriverManager.getConnection(url,user,password); Statement stmtNew=conn.createStatement();11.Sybase数据库//import java.sql.*;Class.forName("com.sybase.jdbc.SybDriver").newInstance();String url =" jdbc:sybase:Tds:localhost:5007/myDB";//myDB为你的数据库名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数据库//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为数据库名Connection conn= DriverManager.getConnection(url); Statement stmtNew=conn.createStatement();13.MySQL数据库//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为数据库名Connection conn= DriverManager.getConnection(url,"root","root"); Statement stmtNew=conn.createStatement();14.PostgreSQL数据库//import java.sql.*;Class.forName("org.postgresql.Driver").newInstance();String url ="jdbc:postgresql://localhost/myDB" //myDB为数据库名String user="myuser";String password="mypassword";Connection conn= DriverManager.getConnection(url,user,password);Statement stmtNew=conn.createStatement();15.access数据库直连用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.程序计时long time1=System.currentTimeMillis();long time2=System.currentTimeMillis();long interval=time2-time1;17.延时try {Thread.sleep(Integer.Parse(%%1));} catch(InterruptedException e) {e.printStackTrace();}18.连接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"; // 不设置数据源String user="myuser";String password="mypassword";Connection conn= DriverManager.getConnection(url,user,password);Statement stmtNew=conn.createStatement();
