@langchain I am going to use OpenAI for LLMs, so get your OpenAI API if you don't have it already.
Here is the quick demo of SQL Agent:

@langchain Step 1:
Add your OpenAI API key to .env file and install all the required modules in virtual env using pip or uv.

@langchain Step 2: Connect to DB and define the Runtime context. (Don't worry about runtime context for now, in the next post I will explain that in detail)
5
@langchain Step 3: Define the tool along with runtime context to execute SQL queries. (more on this in future posts)
6
@langchain Step 4: Define system prompt to let the agent know what it needs to do.

@langchain Step 5: Create the Agent.
As you can see, what we have defined 4 steps are all passed to the agent.
