SQL vs. Python: Which is Better for Machine Learning?

As the world of technology continually evolves, the demand for data-driven insights becomes more significant than ever. The challenge lies not only in getting the data, but also in understanding and extracting valuable information out of it. Two of the most popular tools for data analysis and processing are SQL (Structured Query Language) and Python - this article seeks to compare the two in terms of machine learning capabilities.


SQL is a language used to interact with relational databases. It is a standard for managing data stored in relational databases, and is widely used in all industries. SQL allows users to create, read, update and delete data within a database. It is a declarative language, meaning you tell it what you want and let it figure out how to do it.

SQL has several functions that make it useful for machine learning. One of the most important SQL functions for machine learning is the ability to join data from multiple tables. This means that you can take data from different tables and combine them into a single, easily-readable table. SQL also allows users to aggregate data using functions such as COUNT, SUM, AVG and MAX.

Furthermore, SQL also includes functions for searching and filtering data. You can use WHERE, IN, or LIKE clauses to filter data based on specific criteria. This is especially useful when working with datasets with large amounts of data.

So, what are some of the drawbacks of using SQL for machine learning? Well for one, SQL is not a procedural language. This means that if you want to run complex algorithms or repeat a process several times, it becomes difficult to do so. Additionally, while SQL is very useful for querying and manipulating data, it does not have a lot of developed packages and libraries for machine learning that Python has to offer.


Python is known as a high-level, interpreted programming language that is easy to learn, write, and read. It is popular among machine learning beginners due to its simplicity, and is often a first-choice language in industry. Python comes pre-packaged with pretty much everything that is needed to get started with data analysis and machine learning, such as libraries Numpy, Pandas and Scipy.

The greatest advantage of using Python over SQL is the abundance of libraries and modules specifically designed for machine learning. Python has some of the most advanced deep learning libraries, such as TensorFlow and PyTorch. These libraries utilize advanced algorithms that can operate on large datasets, and enable us to solve complex machine learning problems.

Python also has a number of useful functions built-in. These include generators, data iterators, list comprehensions, and many more. Additionally, Python is a great language for prototyping, meaning you can quickly build and test your ideas without needing to worry too much about the underlying mechanics.

So, what are the drawbacks of using Python for machine learning? It may not be as easy to learn from scratch as SQL. The syntax can be complex, and its speed can be a concern because it is an interpreted language - meaning that it can be slower compared to compiled languages like C++, Java or Fortran. However, with machine learning, it's not always about computational speed, since the bottleneck is often the size of the dataset or the model architecture.

SQL vs. Python

When it comes to choosing between SQL and Python for machine learning, you should look at your use case. SQL is ideal for managing large datasets and querying relational databases. If your data is already in a database, or if you are working with a database-related field, SQL is likely the way to go. SQL is also useful in the backend side of machine learning, where it is used to store the dataset and provide a record of what has been trained.

On the other hand, Python is great for developing more advanced and intricate machine learning models. If your focus is on developing complex models for classification, regression, or deep learning, Python is the language for you. The vast amount of tools, libraries, and resources will mean that you’ll have everything you need to get started.

The two languages could be used in concert, allowing you to make full use of SQL’s querying abilities, while also integrating Python’s libraries and models. By doing this, you’d have great control over different storage, retrieval, processing and analysis stages while also utilizing advanced machine learning techniques.

Ultimately, it all comes down to your preference, time and resources. What are you more comfortable with? How quickly do you need to learn and implement the solution? What other tools will you require?


In conclusion, both SQL and Python are useful in different ways when it comes to machine learning. SQL is designed for querying and manipulating large datasets, while Python is focused on developing more advanced machine learning models. If you have a data problem that requires querying large structured datasets, SQL may be the best choice. If you need advanced machine learning techniques and tools, Python is the way to go.

However, these languages can also be used in concert to create the most innovative and effective machine learning solutions. Using both languages in tandem, you can make the most of SQL’s querying abilities while also taking full advantage of Python’s libraries and models. Whether you’re using one language or both, the key to success with machine learning lies in choosing the right tool for the job, designing and implementing the right architecture, and selecting the best performance metrics to track the improvement of the model over time.
