Chat With Your SQL Database Using Langchain & OpenAI|Tutorial:7

In this episode of the Total Technology Zone channel, Ronnie introduces viewers to using Lang chain with OpenAI's language model to interact with a SQL database. The focus of the tutorial is on generating SQL queries automatically based on user questions and executing these queries on a Microsoft SQL Server. Here's a summary of the key points:

1. **Introduction to the Concept**: Ronnie explains the idea of interacting with a SQL server using Lang chain and OpenAI's language model. The process involves asking questions, which are then translated into SQL queries by the AI.

2. **Setting Up the Environment**: He demonstrates how to set up the environment for this interaction, including using Microsoft SQL Server Management Studio. Ronnie mentions that his SQL Server is locally installed but notes that a remote server can also be used.

3. **Preparing the Database**: The database is already loaded with dummy data for the demonstration. Ronnie shares SQL files for viewers to replicate the setup but skips the installation and data loading steps to save time.

4. **Code Walkthrough**: The main part of the video involves Ronnie walking through a Python script. He explains importing necessary modules from Lang chain, setting up a connection string to the SQL database, and establishing the database connection.

5. **Creating and Using the SQL Toolkit**: Ronnie demonstrates setting up the SQL toolkit in the script, which helps in generating and executing the SQL queries.

6. **Creating Chat Prompts**: A significant part of the process involves creating a chat prompt template to guide the AI in generating appropriate SQL queries. Ronnie provides detailed explanations of the template’s structure and contents.

7. **Running Queries and Interpreting Results**: Various sample questions are asked, like identifying the country with the most customers or the customer with the highest order value, to demonstrate how the system generates and runs SQL queries.

8. **Sharing Resources and Encouraging Practice**: Ronnie promises to share the code and SQL scripts on GitHub. He encourages viewers to write and run the code themselves for better learning and understanding.

The tutorial is comprehensive, focusing on practical application and offering insights into integrating AI with database management for automated query generation and execution.

How to return SQLQuery "action input" just wanna get that :(( any idea ?

[saiveeramalla]

Can you also make on how to deploy ?? From one environment to other ?? May be in databricks mlflow?? Because this is an unexplored topic

I can not connect to my MS SQL server. I got error: Adaptive Server is unavailable or does not exist. What to do? cs =

[raghavendra]

you should also tell the users that. you have to enable TCP/IP ports for all IP addresses in sql server configuration application so that the connection with mssql database is established through python (default port is 1433).

Thanks for video, does this work with memory and context aware? As each time only a single query was demonstrated before restarting, but how does it perform when user makes a second subsequent query without restarting, does it have sufficient context to accurately return correct SQL? say: "based on previous results write the highest single amount etc?"

Can you please tell us the difference in the string if we are using the sql server instead of microsoft authenticator

[FinanciallyWiseTV]

I just want to read from the database without adding any new items to it. How can I do that?

[studiolife]

Thank You. (Just a gentle piece of advice to help your videos : please blow your nose and don't keep sniffing through the video, it was really hard to keep going.)

[tabbasumnaz]

Great work! Can we have any tutorial for same in java?

[-SivaPrasadN]

Can you please, give me a demo video of connecting Oracle database instead of mysql.??
Finally chat with my oracle database and retrieve answer from that database.
Thank you!!!

[gudiatoka]

Do make a full fledged video..also add stremlit web app

[rakeshkumarrout]

is this a extension to codebasics's work?
