How to insert LLM's output into sql table

[sgajiani]

I have an LLM output returned as json. I further apply Structured Output component to create a structured output to pass to "data to Message" component in an attempt to create a "SQL Insert" command which would then become an input to SQL Query component.

However, Data to Message does not support
results[0]['field1'] notation OR results[0].filed1 notation (dot notation)

results[0][ works fine but results[0][ is dict which has keys as column names and values as my column values and I need to be able to access both to construct the Insert Query.

Any ideas on how to insert LLM's output to insert in a sqlite table?

To insert the LLM's output into a SQL table using Langflow, you can follow these steps:

1. Structured Output Component: Use this component to transform the JSON data into a structured format. Ensure that the output schema is correctly defined to match the structure of your SQL table. This will help in organizing the data into key-value pairs where keys are column names and values are the data to be inserted.

2. Data to Message Component: Configure the template to access both keys and values from the structured data. You can use placeholders in the template to format the data for SQL insertion. For example, if your structured data is a list of dictionaries, you can use a template like:

   INSERT INTO your_table (column1, column2) VALUES ({column1}, {column2});
   

   This template will replace {column1} and {column2} with the actual values from the data.

3. Handling Key-Value Access: Since direct dot notation is not supported, ensure your template uses the correct placeholders for accessing dictionary keys. The component will replace these placeholders with the corresponding values.

4. SQL Query Component: Pass the formatted SQL insert command from the Data to Message component to the SQL Query component. Ensure that the database_url is correctly set to your SQLite database and execute the query.

By following these steps, you can construct and execute SQL insert commands using Langflow components. If you encounter issues with accessing keys and values, ensure your template is correctly formatted to match the structure of your data ^[1][2].
