Leveraging the RAG (Retrieve and Generate) technology, the MySQLSearchTool provides users with an efficient means of querying database table content, specifically tailored for MySQL databases. It simplifies the process of finding relevant data through semantic search queries, making it an invaluable resource for users needing to perform advanced queries on extensive datasets within a MySQL database. + +## Installation +To install the `crewai_tools` package and utilize the MySQLSearchTool, execute the following command in your terminal: + +```shell +pip install 'crewai[tools]' +``` + +## Example +Below is an example showcasing how to use the MySQLSearchTool to conduct a semantic search on a table within a MySQL database: + +```python +from crewai_tools import MySQLSearchTool + +# Initialize the tool with the database URI and the target table name +tool = MySQLSearchTool(db_uri='mysql://user:password@localhost:3306/mydatabase', table_name='employees') + +``` + +## Arguments +The MySQLSearchTool requires the following arguments for its operation: + +- `db_uri`: A string representing the URI of the MySQL database to be queried. This argument is mandatory and must include the necessary authentication details and the location of the database. +- `table_name`: A string specifying the name of the table within the database on which the semantic search will be performed. This argument is mandatory. + +## Custom model and embeddings + +By default, the tool uses OpenAI for both embeddings and summarization. To customize the model, you can use a config dictionary as follows: + +```python +tool = MySQLSearchTool( + config=dict( + llm=dict( + provider="ollama", # or google, openai, anthropic, llama2, ... + config=dict( + model="llama2", + # temperature=0.5, + # top_p=1, + # stream=true, + ), + ), + embedder=dict( + provider="google", + config=dict( + model="models/embedding-001", + task_type="retrieval_document", + # title="Embeddings", + ), + ), + ) +) +``` diff --git a/src/crewai_tools/tools/mysql_seach_tool/mysql_search_tool.py b/src/crewai_tools/tools/mysql_seach_tool/mysql_search_tool.py new file mode 100644 index 000000000..226fb1ddd --- /dev/null +++ b/src/crewai_tools/tools/mysql_seach_tool/mysql_search_tool.py @@ -0,0 +1,44 @@ +from typing import Any, Type + +from embedchain.loaders.postgres import PostgresLoader +from pydantic.v1 import BaseModel, Field + +from ..rag.rag_tool import RagTool + + +class PGSearchToolSchema(BaseModel): + """Input for PGSearchTool.""" + + search_query: str = Field( + ..., + description="Mandatory semantic search query you want to use to search the database's content", + ) + + +class PGSearchTool(RagTool): + name: str = "Search a database's table content" + description: str = "A tool that can be used to semantic search a query from a database table's content." + args_schema: Type[BaseModel] = PGSearchToolSchema + db_uri: str = Field(..., description="Mandatory database URI") + + def __init__(self, table_name: str, **kwargs): + super().__init__(**kwargs) + self.add(table_name) + self.description = f"A tool that can be used to semantic search a query the {table_name} database table's content." + self._generate_description() + + def add( + self, + table_name: str, + **kwargs: Any, + ) -> None: + kwargs["data_type"] = "postgres" + kwargs["loader"] = PostgresLoader(config=dict(url=self.db_uri)) + super().add(f"SELECT * FROM {table_name};", **kwargs) + + def _run( + self, + search_query: str, + **kwargs: Any, + ) -> Any: + return super()._run(query=search_query)
