[FireDAC] Access to the connection object using Connection Definition Name

[Jacek Laskowski 57]

I use private connection definition configured by Connection Definition Name.

 

FDQuery1.ConnectionName := 'Ora_Demo';
FDQuery1.Open('select * from "Customers"');

But now I need to assigned events on FDConnection level:

 

  Connection.OnRecover := ...;
  Connection.OnRestored := ...;
  Connection.OnLost := ...;

How can I do this when I have only Query and the Connection is automatically created from the connection pool?

• clear FDQuery1.ConnectionName
• add a TFDConnection 
• set its ConnectionDefName to your need
• set FDQuery1.Connection to that connection

Ok, I know this  solution, but I search for other, without TFDConnection, I use a FireDAC connection pooling.

You are still using connection pooling with this approach. Connection pooling doesn't pool TFDConnection but TPhysConnections which can be accessed by TFDConnection.ConnectionIntf.
