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
您好我有以下代码连接到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32位。但仍然得到错误
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();
}
}
}
如何我有SQL Workbench工具，我可以通过它连接到它但不通过Java代码。
How ever I have SQL Workbench tool through which I can connect to it but not through java code.
由于我在过去3个小时内在谷歌搜索时遇到困难，所以请急需帮助。
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，那么 DRIVER = {Microsoft Access Driver（* .mdb）} 因为没有64位版本的Jet数据库引擎而无法工作。您可以...
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，然后使用
DRIVER = {Microsoft Access Driver（代码中有* .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.
...或...
- 使用 UCanAccess Access数据库的JDBC驱动程序。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（已经删除了JDBC-ODBC Bridge）。有关详细信息，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:
