Disconnect in multithreading

[Delian]

Hi,

I'm using server MS SQL 2014. I have issue with disconnect in multithreading. Connect and disconnect is working with one thread. When disconnect in the second thread, i have exception. I have attached call stack.

Exception occurs with codetyphon 5.7 with ZeosLib 7.2.0.41 and Delphi XE7 with ZeosLib 7.1.4-stable.

Exception occurs also in designtime.

Code: Select all

- create empty project
- Add and configure first TZConnection in main form.
- add and configure second TZConnection in main form.
- connect first connection.
- connect second connection.
- disconnect first connection.
- try to disconnect second connection <- Got exception:(

Hello Delian,

please don't use ntwdblib.dll and the mssql driver because the ntwdblib.dll is not supported by Microsoft anymore. Please use FreeTDS or OleDB from Zeos7.3.
With best regards,

Jan
