从Java 8开始,JDK将不再包含JDBC-ODBC Bridge.

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); // classNotFoundException is thrown

有没有其他解决方案连接JDBC-ODBC Bridge？

我创建了一个MS Access数据库并为其分配了一个DSN.我想通过我的Java应用程序访问它.

这就是我在做的事情:

public class AccessDbConnection {

    public static void main(String[] args) {
        System.out.println("**ACCESS DB CONNECTION**");

        try {
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); // for MS Access ... MS access driver loading

            String     conURL    = "jdbc:odbc:sampleDNS";
            Connection con       = DriverManager.getConnection(conURL);
            Statement  statement = con.createStatement();
            String     qry       = "SELECT * FROM Table1";
            ResultSet  rs        = statement.executeQuery(qry);

            while(rs.next()) {
                String id    = rs.getString("ID") ;
                String fname = rs.getString("First_Name");
                String lname = rs.getString("Last_Name");
                System.out.println(id + fname + lname);
            }
        } catch (ClassNotFoundException ex) {
            System.out.println("Classforname Exception!!");
            Logger.getLogger(AccessDbConnection.class.getName()).log(Level.SEVERE, …

任何人都可以提一下最好的开源odbc:jdbc驱动程序来读/写dbf.我有一个dbf文件,我想通过Web应用程序(Tomcat应用程序)查询(选择/更新).

任何帮助/提示都会很有意义.

谢谢.

我有非常简单的代码:

pstat=con.prepareStatement("select typeid from users where username=? and password=?");             
pstat.setString(1, username);
pstat.setString(2, password);
rs=pstat.executeQuery();
int rowCount=0;
while(rs.next())
{       
    rowCount++;         
}
rs.beforeFirst();
if(rowCount>=1)
{
while(rs.next())
{
    typeID=rs.getInt(1);
}

但是当执行这段代码时我得到了......

我目前正在为我的大学的一个班级做一个项目.我正在学习连接和操作数据库,我们正在使用Microsoft .accdb文件.

这是我到目前为止所拥有的.

/* Perform database operations */
    try {
        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        System.out.println("Driver loaded");

        connection = DriverManager.getConnection("jdbc:odbc:Lab3.accdb");
        System.out.println("Database connected");

        statement = connection.createStatement();

        ResultSet resultSet = statement.executeQuery("");

        while (resultSet.next()) {
            output.write("<p>" + resultSet.getString(1) + "\t" +
                resultSet.getString(2) + "\t" + resultSet.getString(3) + "</p>");
        }

        connection.close();
    } catch (ClassNotFoundException|SQLException e) {
        System.out.println("Database Access Error.");
        e.printStackTrace();
    }

在寻找"sun.jdbc.odbc.JdbcOdbcDriver"时,我得到以下输出.

Java 8不再支持JDBC-ODBC桥.有没有办法在Java 8中没有桥接器的情况下访问旧版MDB文件？遗产,我的意思是Access 2.0.UCanAccess不支持这样的旧版本,这是在这里提出的.

我正在尝试使用C++为Windows环境(如PostgreSQL,Simba,Firebird等)创建自定义ODBC驱动程序,因为ODBC API 默认具有多个ODBC API方法.

我使用DSN建立了连接,并且我能够使用SQLExecuteDirect方法执行SQL查询.

但是,在将Excel与我们的ODBC驱动程序连接时,我无法将表列表绑定到Microsoft查询向导.

该SQLTABLES() ,SQLBindColumn() ,并且调用SQLFetch()方法用于检索这里的表名列表.使用SQLBindColumn方法绑定数据.

但我对如何检索表名并将它们绑定到Excel感到困惑？

package sqlselection;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class Sqlselection 
    {
        public static void main(String[] args)
        {
            try
            {
                Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");

                String userName = "sa";
                String password = "password";
                String url = "jdbc:microsoft:sqlserver://localhost:1433"+";databaseName=AdventureWorks2008R2";
                Connection con = DriverManager.getConnection(url, userName, password);
                Statement s1 = con.createStatement();
                ResultSet rs = s1.executeQuery("SELECT TOP 1 * FROM HumanResources.Employee");
                String[] result = new String[20];
                if(rs!=null){
                    while (rs.next()){
                        for(int i = 0; i <result.length ;i++)
                        {
                            for(int j = 0; j <result.length;j++)
                            {
                                result[j]=rs.getString(i);
                            System.out.println(result[j]);
                        } …

我尝试了以下方法:

private String password = "";
private String dbName = "dataHC.accdb";
private String bd = dbName + ";PWD=" + password;
String  url   = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ="+bd+";";

private Connection conn = null;

//Connect
public void connect() {
    try{
        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        conn = DriverManager.getConnection(url);
        if (conn != null)
            System.out.println("Conexión a base de datos "+dbName+". listo");
    }catch(SQLException e){
        System.out.println(e);
    }catch(ClassNotFoundException e){
        System.out.println(e);
    }
}

我得到了这个错误:

特别

在我的应用程序中,我使用20个线程来完成工作.每个线程调用远程Web服务并更新Oracle DB.Jboss重启后,作业无法更新数据库,但我在日志中找到的例外情况如下:
