Access database connection error solution

64位Windows系统连接Access数据库，程序中可能需要修改Access数据库连接：

32位：String strUrl = "jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};DBQ=c://demo.mdb"

64位：String strUrl = "jdbc:odbc:driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=c://demo.mdb"

修改后仍报错则进入“控制面板”-》“管理工具”-》“数据源（ODBC）”查看系统是否存在Access驱动

若不存在则需要安装Microsoft Access驱动程序：

下面是连接access的.mdb文件，解析代码：
