How to query database using langraph.

[kaurdp]

I've implemented database agents in langchain but unable to implement database agent in langraph. langraph agents working accurately for answering queries from openweb but not querying database. I have searched the documentation but I don't see anything regarding this or how it could be done, according to the documentation in Langchain I only find langchain agents to query database . Have anyone of you an idea of how this can be done?

The customer service bot tutorial queries a database. In general you can interact with a DB in two ways:

1. Define functions as tools that expose specific queries the agent can make
2. Define a DB tool that lets the agent write the actual sql query

In either case, including examples in the docstrings about the schema, etc. is pretty important
