Example #1

bool DatabaseMysql::BeginTransaction()
{
    if (!mMysql)
        return false;

    // don't use queued execution if it has not been initialized

    TransactionQueues::iterator i = m_tranQueues.find(tranThread);
    if (i != m_tranQueues.end() && i->second != NULL)
        // If for thread exists queue and also contains transaction
        // delete that transaction (not allow trans in trans)
