Unable to Manage Transactions
Posted by: Joseph Wozniak

I am new to MySql. I have been using SqlLite. Using C++/Qt on Windows.
I seem to have no problems selecting, updating, inserting. I have moved much code from SqlLite to MySql with no problem except one. I cannot get transactions to work. It acts as if AutoCommit is on always. If I begin a transaction, encounter an error and then rollback, nothing gets rolled back.

My initial investigation pointed to the Server configuration whether or not my tables are InnoDB. They are. I then ran the same sql code from the WorkBench 6.3 CE and my transactions work. So, I believe the Server is set up correctly.

From my C++ code, when I ask the MySql driver if it has transaction support, it comes back false. Really, I am using Qt to ask the driver and it returns false. When I look into the Qt code for that, it is looking for CLIENT_TRANSACTIONS.

I am using the MySql Driver from my install directory Program Files (x86)\MySQL\MySQL Connector C 6.1\lib\libmysql.dll

Again, everything seems to work fine except transactions.

Can you help me move forward with this?
thanks.
