Refactor DatabaseHandler to use local Statement objects#91
Refactor DatabaseHandler to use local Statement objects#91
Conversation
Refactored `DatabaseHandler.java` to remove the static shared `Statement` field, which was causing concurrency issues and potential resource leaks. - `execQuery`: Now uses a local `Statement` and calls `closeOnCompletion()` to ensure the statement is closed when the returned `ResultSet` is closed. - `execAction`: Now uses a local `Statement` within a try-with-resources block for automatic resource management. - Improved error handling in `execQuery` to close the statement if an exception occurs during execution. This change improves thread safety and resource management in database operations. Co-authored-by: G30RG3-GJ <203693057+G30RG3-GJ@users.noreply.github.com>
