Answer

Yes, you can connect to your RDBMS by setting up the appropriate connection string, creating an instance of the SQLDatabase class, and using a language model with SQLDatabaseChain. Make sure to replace the connection string and database-specific details with the ones relevant to your RDBMS.

docs/integrations/databricks.ipynb

The content is relevant to the question because it provides information on how to connect to a Databricks RDBMS using the SQLDatabase wrapper of LangChain. The example demonstrates the installation of the required package, the method to connect to Databricks, and the required parameters for the connection.

docs/modules/agents/toolkits/examples/sql_database.ipynb

The content is relevant to the question because it provides an example of how to connect to an RDBMS (in this case, SQLite) using the SQLDatabase module. The example demonstrates how to initialize the connection, create an SQL agent, and execute queries on the database. This information can be helpful for someone looking to connect to their RDBMS.

Yes, you can connect to your RDBMS using the SQLDatabaseChain in the provided example. The example demonstrates how to set up a connection to an SQLite database, create a chain using a language model, and make predictions using the chain. You can follow these steps to connect to your RDBMS:

1. Set up your database connection using the appropriate connection string for your RDBMS.
2. Create an instance of the SQLDatabase class with the connection string.
3. Create an instance of the OpenAI class for the language model.
4. Create a SQLDatabaseChain using the instances of SQLDatabase and OpenAI.
5. Use the chain to make predictions and interact with your RDBMS.

Make sure to replace the connection string and database-specific details with the ones relevant to your RDBMS.

docs/modules/chains/examples/sqlite.ipynb

The content is relevant to the question because it provides information on how to connect to various SQL databases using the SQLDatabaseChain in the LangChain library. It also demonstrates how to use SQLAlchemy to connect to different SQL dialects, such as MS SQL, MySQL, MariaDB, PostgreSQL, Oracle SQL, Databricks, and SQLite. The example provided uses SQLite and the Chinook database to demonstrate the connection process.

#35

Yes, the PR description indicates that an SQL database has been added to the repository. This means you should be able to connect to your RDBMS. However, you will need to provide more information about the specific RDBMS you are using and the connection details to give a more accurate answer.

I mean, my own RDBMS. Not supported by SQLAlchemy, not MS SQL, MySQL, MariaDB, PostgreSQL, Oracle SQL, Databricks and SQLite and other popular databases.

Probably not, because the first thing the agent does is queries the names of the tables on the database, then gets the schema (column names etc) of the most relevant tables. Without SQL Alchemy or more information about the database engine, it wouldn't know how to do this, since getting a list of the tables on the database is implementation dependent. SQL Alchemy hides that complexity.

Hi, @microyybar! I'm Dosu, and I'm helping the LangChain team manage their backlog. I wanted to let you know that we are marking this issue as stale.

From what I understand, the issue is about connecting to a relational database management system (RDBMS). There have been some discussions in the comments, with suggestions on how to connect to an RDBMS using the appropriate connection string, creating an instance of the SQLDatabase class, and using a language model with SQLDatabaseChain. However, it seems that without SQL Alchemy or more information about the database engine, it wouldn't be possible to connect to the RDBMS.

Before we close this issue, we wanted to check with you if it is still relevant to the latest version of the LangChain repository. If it is, please let us know by commenting on the issue. Otherwise, feel free to close the issue yourself, or it will be automatically closed in 7 days.

Thank you for your understanding and contribution to the LangChain project!
