Named 命令

适用于：Access 2013、Office 2013

可以设置 Command 对象的 Name 属性，然后通过将该命令视为 Command 对象的 ActiveConnection 属性的方法来调用它，从而执行该命令。 以下示例说明了这种情况，该示例将命令命名为 GetCustomers。 请注意，代码将声明的和实例化的 Recordset 对象传递到 GetCustomers“方法”。如果 命令需要参数，还可以将参数传入到“方法”。

 On Error GoTo ErrHandler:

 objCmd.CommandType = adCmdText 
 
 'Name the command. 
 objCmd.Name = "GetCustomers" 
 
 objCmd.ActiveConnection = objConn
