Vanna.i + SQLite + ChromaDB : Model doesn't retrieve the data from the table #582

Closed tifDev closed 3 months ago

Describe the bug A clear and concise description of what the bug is.

Python script:

from vanna.ollama import Ollama from vanna.chromadb import ChromaDB_VectorStore

class MyVanna(ChromaDB_VectorStore, Ollama): def init(self, config=None): ChromaDB_VectorStore.init(self, config=config) Ollama.init(self, config=config)

vn = MyVanna(config={"model": "llama3.1"})

vn.connect_to_sqlite("./data/mydatabase.db")

df_ddl = vn.run_sql("SELECT type, sql FROM sqlite_master WHERE sql is not null")

for ddl in df_ddl["sql"].to_list(): vn.train(ddl=ddl)

The following are methods for adding training data. Make sure you modify the examples to match your database.

DDL statements are powerful because they specify table names, colume names, types, and potentially relationships

vn.train( ddl=""" CREATE TABLE users ( id INT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(100), email VARCHAR(100) ); """ )

Sometimes you may want to add documentation about your business terminology or definitions.

vn.train( documentation="Our business defines OTIF score as the percentage of orders that are delivered on time and in full" )

You can also add SQL queries to your training data. This is useful if you have some queries already laying around. You can just copy and paste those from your editor to begin generating new SQL.

vn.train(sql="SELECT * FROM users WHERE name = 'John Doe'")

At any time you can inspect what training data the package is able to reference

training_data = vn.get_training_data() training_data

You can remove training data if there's obsolete/incorrect information.

vn.remove_training_data(id='1-ddl')

vn.ask(question="What is the email from John Doe?")

DB details


sqlite> 
CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100),
    email VARCHAR(100)
);
sqlite> INSERT INTO users (name, email) VALUES ('John Doe', 'john.doe@example.com');
sqlite> select * from users;
|John Doe|john.doe@example.com
|Jane Smith|jane.smith@example.com
sqlite> SELECT * FROM users WHERE name = 'John Doe';
|John Doe|john.doe@example.com
