如何从 64 位 Java 连接到 Access .mdb 数据库? [英] How to connect to Access .mdb database from 64-bit Java?
问题描述
我有以下代码可以连接到 Windows 7 操作系统上的 MS Access 数据库.我已将数据源快捷方式更改为指向 64 位 odbc,然后指向 32 位.但仍然收到错误
Hi I have the below code to connect to MS Access database on Windows 7 OS. I have changed the Data Source short cut to point to 64bit odbc then 32 bit. But still getting the error as
java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
at sun.jdbc.odbc.JdbcOdbc.createSQLException(JdbcOdbc.java:6956)
at sun.jdbc.odbc.JdbcOdbc.standardError(JdbcOdbc.java:7113)
at sun.jdbc.odbc.JdbcOdbc.SQLDriverConnect(JdbcOdbc.java:3072)
at sun.jdbc.odbc.JdbcOdbcConnection.initialize(JdbcOdbcConnection.java:323)
at sun.jdbc.odbc.JdbcOdbcDriver.connect(JdbcOdbcDriver.java:174)
at java.sql.DriverManager.getConnection(DriverManager.java:579)
at java.sql.DriverManager.getConnection(DriverManager.java:221)
at TestDBConnection.main(TestDBConnection.java:21)
我的代码是:
import java.sql.Connection;
import java.sql.DriverManager;
public class TestDBConnection {
public static void main(String[] args) {
// TODO Auto-generated method stub
try
{
System.out.println("filename");
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String database =
"jdbc:odbc:DRIVER={Microsoft Access Driver (*.mdb)};DBQ=C:\Test\Tests.mdb";
Connection conn = DriverManager.getConnection(database, "", "");
} catch(Exception ex) {
ex.printStackTrace();
}
}
}
我如何拥有 SQL Workbench 工具,通过它我可以连接到它,但不能通过 Java 代码连接到它.
How ever I have SQL Workbench tool through which I can connect to it but not through java code.
请急需帮助,因为我在过去 3 小时在 Google 上搜索时一直在为此苦苦挣扎.
Please need help badly as I am struggling with this from past 3 hours searching on Google.
推荐答案
如果您的 Java 应用程序在 64 位 Java 虚拟机 (JVM) 中运行,则 DRIVER={Microsoft Access Driver (*.mdb)}
不会工作,因为没有 64 位版本的 Jet 数据库引擎.你可以...
If your Java app is running in a 64-bit Java Virtual Machine (JVM) then DRIVER={Microsoft Access Driver (*.mdb)}
is not going to work because there is no 64-bit version of the Jet database engine. You can...
- 从 此处,然后在代码中使用
DRIVER={Microsoft Access Driver (*.mdb, *.accdb)}
.
- Download and install the 64-bit version of the Microsoft Access Database Engine from here, and then use
DRIVER={Microsoft Access Driver (*.mdb, *.accdb)}
in your code.
...或...
- 在 32 位 JVM 中运行您的 Java 应用程序并继续使用现有的
DRIVER=
字符串.如果您选择此选项,此处的相关答案可能会有所帮助.
- Run your Java app in a 32-bit JVM and continue to use the existing
DRIVER=
string. The related answer here might prove helpful if you choose this option.

- 将 UCanAccess JDBC 驱动程序用于 Access 数据库.它是一个免费的、开源的、纯 Java 实现,因此它适用于 32 位和 64 位系统,包括 Windows 和非 Windows.它也适用于 Java 8(已删除 JDBC-ODBC 桥).有关更多详细信息,请参阅:
- Use the UCanAccess JDBC driver for Access databases. It is a free, open-source, pure Java implementation so it works on both 32-bit and 64-bit systems, both Windows and non-Windows. It also works with Java 8 (which has dropped the JDBC-ODBC Bridge). For more details, see:
