jsp连接access数据库
JSP连接ACCESS,不过得设置ACCESS的数据源,然后:
import java.sql.*;
public class sql_data{
String sDBDriver = "sun.jdbc.odbc.JdbcOdbcDriver";
String sConnStr = "jdbc:odbc:news";
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
public sql_data()
{
try
{Class.forName(sDBDriver);
}
catch(java.lang.ClassNotFoundException e)
{
System.err.println("sql_data(): " + e.getMessage());
}
}
public void executeInsert(String sql)
{
try
{
conn = DriverManager.getConnection(sConnStr);
stmt = conn.createStatement();
stmt.executeUpdate(sql);
stmt.close();
conn.close();
}
catch(SQLException ex)
{System.err.println("sql_data.executeUpdate:"+ex.getMessage());
}
}
public ResultSet executeQuery(String sql)
{
try
{
conn = DriverManager.getConnection(sConnStr);
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY);
rs = stmt.executeQuery(sql);
}
catch(SQLException ex)
{
System.err.println("sql_data.executeQuery:"+ex.getMessage());
}
return rs;
}
public void executeUpdate(String sql)
{
try {
conn = DriverManager.getConnection(sConnStr);
stmt = conn.createStatement();
stmt.executeUpdate(sql);
stmt.close();
conn.close();
}
catch(SQLException ex) {
System.err.println("aq.executeQuery: " + ex.getMessage());
}
}
public void executeDelete(String sql)
{
try
{
conn = DriverManager.getConnection(sConnStr);
stmt = conn.createStatement();
stmt.executeUpdate(sql);
stmt.close();
conn.close();
}
catch(SQLException ex)
{
System.err.println("sql_data.executeDelete:"+ex.getMessage());
}
}
public void closeStmt(){
try{
stmt.close();
}
catch(SQLException e){
e.printStackTrace();
}
}
public void closeConn(){
try{
conn.close();
}
catch(SQLException e){
e.printStackTrace();
}
}
