body: <p>How can I add row to my table in database, use the sqlalchemy?
  I use next code:</p>
  
  <pre><code>   for i in range(count):
          name = Utils.uniqID()
          class name(Base):
              __tablename__ = name
              first = Column(Integer, primary_key = True)
              second = Column(String)
              third = Column(String)
  
              def __init__(self, first = None, second = None, third = None):
                  self.first = first
                  self.second = second
                  self.third = third
  
          Base.metadata.create_all(engine)
  </code></pre>
  
  <p>I'm trying to add rows with next code:</p>
  
  <pre><code>def insertRandomRows(engine, table, count):
      rows = []
      for i in range(count):
