  I fixed some bugs, it's better to follow these steps:
  1. Put your sqlite db file to replace try1024.db. 
  2. Open chatdb.py, set init_db = True to False, to disable create and insert sample data.
  3. Open table_schema.py and add your table schema and then add these variables to `tables` list at the bottom.
  4. Run chatdb.py
  5. Input your query, like the demo above.
  Also, you can change sql_examples.py to use your own examples.
