MindsDB provides the from_env() function that lets users pull values from the environment variables into MindsDB.

​
Usage

Here is how to use the from_env() function.

  • Save the environment variable into a variable using the from_env() function (or saving the value directly).
SET @my_env_var  = from_env("MDB_MY_ENV_VAR")

SET @my_value  = "123456"

Note that due to security concerns, only the environment variables with name starting with MDB_ can be extracted with the from_env() function.

  • Use this variable to pass parameter while creating object in MindsDB.

Here is an example for knowledge bases.

CREATE KNOWLEDGE_BASE my_kb
USING
    embedding_model = {
       "provider": "openai",
       "model_name" : "text-embedding-3-large",
       "api_key": @my_env_var
    },
    ...;
