Create a SQL Agent using CrewAI and Groq
Introduction
Here we are about to create a build a team of agents that will answer complex questions using data from a SQL database.
Within the context of a team, an agent can be envisioned as an individual team member assigned with specific expertise and responsibilities. These agents assume distinct roles, such as ‘Researcher,’ ‘Writer,’ or ‘Customer Support,’ each playing a vital part in fulfilling the collective objectives of the team. Here we will follow the below approach:
- Connect Agents with a SQL database
- Set up agent tools for writing SQL queries
- Build a team of agents that uses Llama 3 to analyze data
Integrating SQL with Agents
Envision granting your AI the authority to interact directly with your confidential data. This is what occurs when you link agents to a SQL database. It’s a masterful workaround that transcends the traditional text-based RAG (Retrieval-Augmented Generation) method.
What makes this so remarkable?
By leveraging SQL, your AI can effortlessly filter and search data with unparalleled flexibility. The AI then crafts responses based on the exact results retrieved from the database, ensuring precision and accuracy.
Why SQL Databases?
- They’re tried and true: SQL databases are the backbone of many applications.
- Reliable and fast: They can handle lots of data quickly and safely.
- our data is already there: Many businesses already store important information in SQL databases.
Traditional RAG uses chunks of text for context. But here the SQL approach is different. It offers the following:
- Flexible searching: The AI can use SQL to filter and find exactly what it needs
- Better answers: The AI generates responses based on precise data results
- Scalability: SQL databases handle massive amounts of data with ease
- Data integrity: SQL keeps your data consistent and connected
Technology Components Required
CrewAI :
CrewAI, an innovative open-source framework, allows users to harness the power of intelligent agents working collaboratively. In contrast to conventional chatbots, these agents possess the ability to collaborate, exchange information, and tackle intricate tasks as a cohesive team.
Envision a group of experts collaborating harmoniously. Each member possesses unique expertise and knowledge, yet their ability to communicate and distribute responsibilities results in accomplishments surpassing individual capabilities. CrewAI applies this collaborative principle to the realm of AI. Within this framework, individual agents, each with distinctive strengths and limitations, interact under the orchestration of CrewAI, ultimately achieving shared objectives.
GROQ:
Groq is a pioneering platform that seamlessly integrates cutting-edge hardware and software components, renowned for its outstanding computational speed, exceptional quality, and remarkable energy efficiency. At the heart of Groq’s offerings is the LPU™ Inference Engine.
The LPU Inference Engine, also known as the Language Processing Unit™, is a state-of-the-art system that combines advanced hardware and software elements. This revolutionary end-to-end processing unit is engineered to deliver unparalleled compute speed, superior quality, and exceptional energy efficiency. The LPU Inference Engine excels in providing rapid inference for computationally intensive applications, particularly for sequential components like AI language applications, including the impressive Large Language Models (LLMs)
Here we will use Llama3 70B to drive our agents.
Implementation Details of SQL Agent
Steps Involved:
- Create tools to interact with the Database
- Create a Database Developer Agent to construct and execute SQL queries.
- Create A Data Analyst Agent to analyze the database data response and write a detailed response.
- Create a Editor Agent to write an executive summary based on the analysis.
- Create tasks to extract data based on the user query, analyze the data extracted and write a report based on the analysis provided.
- Llama3–70B is used as the LLM
Code Implementation
Implemented in google colab using high ram cpu.

1. Albania: $10,000
2. Armenia: $15,000
3. Bosnia and Herzegovina: $18,000
4. Bulgaria: $20,000
5. Croatia: $22,000
**Company Size:**
The data suggests that salaries tend to increase with company size. The average salaries for different company sizes are:
1. Large companies: $83,419
2. Medium companies: $54,391
3. Small companies: $43,419
**Employee Experience:**

1. Executive: $134,419
2. Senior: $83,419
3. Mid-level: $54,391
4. Entry-level: $43,419
**Interaction between Company Location and Company Size:**
The data suggests that the effect of company size on salary varies across different countries. For example, in the United States, large companies tend to pay significantly higher salaries than small companies, while in India, the difference in salaries between large and small companies is relatively small.
**Interaction between Company Location and Employee Experience:**
The data suggests that the effect of employee experience on salary varies across different countries. For example, in the United States, executives tend to earn significantly higher salaries than entry-level employees, while in India, the difference in salaries between executives and entry-level employees is relatively small.
Overall, the analysis suggests that salaries are influenced by a combination of factors, including company location, company size, and employee experience. Understanding these factors can help companies develop more effective compensation strategies to attract and retain top talent.
