Hello.
I removed the transaction start/commit and it worked successfully.
But we can not work without transactions.

Hello,

Try to reproduce the problem on a "clean" PC (without Delphi and our dbExpress driver), having copied only the application and the dbexpoda.dll library, installed and configured the Oracle client.

Hello.
All our clients are working on "clean" PC. Today I ran the test from one of them. Error same, but in other iterations.
First pressing the button gives an error for the third time:
"Access violation at addess 013629C3 in module 'dbexpoda.dll'. Read of address 0175C000 i=3"
Second pressing the button gives an error immediately:
"Access violation at addess 013629C3 in module 'dbexpoda.dll'. Read of address 0175C000 i=1"
The third and subsequent pressing does not make mistakes.

2007 driver (dbexpoda.dll) works fine with no errors.
The bug had appeared in the driver 2012.

Hello,

We cannot reproduce the problem on our servers and PCs. If you are able to open remote access to your Oracle server, we will try to reproduce the problem on your real server.

Hello,

Unfortunately, we couldn't raise your dump due to errors. If you can open access to your server (ip, port, sid, login, password) for us, please send this data to my e-mail - and we will check this problem directly on your DB.

Hello,

I've received your letter, however, when attempting to connect, Oracle returns the Unknown SID error. Please send the record from the tnsnames.ora file for connection to your server.
