Closing non transactional SqlSession

As an AI language model, I don't have the context about which programming language you are using for SqlSession. However, in general, it is important to always close non-transactional SqlSession objects to release resources and avoid memory leaks.

Here's an example code snippet in Java using MyBatis to close a non-transactional SqlSession:

SqlSession sqlSession = sqlSessionFactory.openSession();
try {
   // perform database operations here...
} finally {
   sqlSession.close();
}

In this code snippet, we open a new SqlSession using `sqlSessionFactory.openSession()` and perform the database operations inside a try block. After the execution of the try block, we call the `close()` method on the SqlSession object inside a finally block to ensure that it is closed even if there is an exception thrown.

Closing the non-transactional SqlSession in this way ensures that the resources associated with it are released properly and the connection is returned to the connection pool.
