tadconnection and drivername AFTER reconnection 2012/06/26 01:41 (10 Months, 3 Weeks ago)
Hi,
I have a tadconnection set with the option to autoreconnect.

If server is up and i do:

AdConnection.Connected := True;
Then AdConnection.DriverName is correct (MySQL).

But, if server is down AdConnection will try 3 times to reconnect. Let's say that the first 2 times it cannot connect but at the third try it will then

AdConnection.DriverName will be equal to ''.

Is it a bug?

Thanks,
Lorenzo

Hello

If you are using a persistent connection definition (ConnectionDefName specified), then DriverName will return a value only when the connection is active. Otherwise it will be empty.

So, if AnyDAC failed to recover the connection, then it will be closed. After that DriverName will be empty.

Hi,

But the problem is that if it fails the 1st time, and the 2nd connects then drivername will still be ''...

Ok, fixed. To apply the fix:
- open uADCompClient
- locate there TADCustomConnection.ReleaseConnectionIntf method
- and the line in this method:
Code:
  lMain := AConnIntf = FConnectionIntf;

- then replace the line with
Code:
  lMain := @AConnIntf = @FConnectionIntf;


Please let me know how it works.
