FireDAC EventAlerter演示

Question

我正在Win10 Pro上使用Delphi 10.2.3，并且在EventAlerter演示中遇到了问题

  

Samples \ Object Pascal \ Database \ FireDAC \ Samples \ Comp Layer \ TFDEventAlerter \ Main

文件夹。

如果我运行演示，请在组合框中选择EMPLOYEE条目，然后单击Register events和Fire events按钮，我会收到错误消息

FireDAC Error
The application performed an incorrect operation with the database.
-------------------------------------------
Message text: Dynamic SQL Error
SQL error code = -104
Token unknown - line 1, char 9
block
Error code: 335544569
Error kind: Other
Server object: 
Command text offset: 
-------------------------------------------
Command text: execute block as
begin
  post_event 'EV1';
  post_event 'EV1';
  post_event 'EV2';
end
Command parameters:
-------------------------------------------
Exception class name: EIBNativeException
FireDAC error code: 1400
FireDAC object name: frmMain.qryFireEvents

无论将Supported event kinds设置为<default>还是Events，都会发生这种情况。

错误消息似乎在抱怨execute block。我不是Interbase专家，但给人的印象是execute block是FireBird构造，而不是Interbase构造，并且我在IBXE7文档中找不到对其的引用。我已验证，一旦将组合设置为EMPLOYEE，dmMainComp.Pas中DriverName的{​​{1}}就设置为DBMain。

我的问题是如何避免此错误？
