Dear Andrey,

please would you be so kind and send me the full version of dbExpress driver.

We bought the driver on 13th January (company KP-SYS)

But official downloads doesnt enable to download version 4.3.5 - there is 4.3.4 from october only.

Or can you upload new version for official download??

My demo version licence is over and I can't work!!

Thank you in advance

Tom

Hello,
I use RAD Studio 10 Seattle, and can't make read-only transactions

Code: Select all

procedure TMainForm.BitBtnClick(Sender: TObject);
var
  tr: TTransactionDesc;
begin
  SQLConnection.Open;
  tr.IsolationLevel := xilCUSTOM;
  tr.CustomIsolation := 1; // flag that transaction is read-only
  SQLConnection.StartTransaction(tr);
end;
- not workimg,

and

Code: Select all

SQLConnection1->BeginTransaction(5)
return

Code: Select all

---------------------------
Debugger Exception Notification

Project MyApp.exe raised exception class TDBXError with message 'unknown ISC error 0'.

This code won't work due to the reasons specified in the first posts of this topic.

To solve the problem, please try to specify the exact path to the client library of your Firebird. For example:

Code: Select all

SQLConnection1.Params.Values['VendorLib']: = 'C:\Program Files\Firebird\Firebird_3_0\fbclient.dll';
