连接数据库的方法如下: using System.Data.Odbc; string connectionString = "DSN=SampleLib"; // 设置数据源名称 OdbcConnection conn = new OdbcConnection(connectionString); 示例代码如下: using System; using System.Data.Odbc; namespace OdbcExample { class Program { static void Main(string[] args) {...
以下示例创建一个OdbcCommand和一个OdbcConnection。 将打开OdbcConnection并将其设置为Connection属性。 然后,该示例将调用ExecuteNonQuery并关闭连接。 为此,ExecuteNonQuery传递连接字符串和查询字符串,该字符串是 SQL INSERT 语句。 csharp staticprivatevoidInsertRow(stringconnectionString){stringqueryString ="INSERT INTO...

I tried with the DSN-less connection string: jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=I:/TeamForge/ORS/CTFORS.accdb and I tried with the DSN connection, using both the System32 and SysWOW64 versions of the ODBC Admin, and none of that worked. W...
数据源(dsn):是ODBC与数据库之间建立连接的依据,包括数据源名称、数据源描述,数据库驱动程序、数据库服务器地址、数据库端口号、数据库名称等。 ODBC驱动程序:ODBC与数据库之间的接口 驱动程序管理器:将应用程序对ODBC API的调用传递给正确的驱动程序,而驱动程序执行完操作之后得到结果返回给应用程序。
