I’m currently learning SQL and recently wrote a simple beginner-friendly article about SQL transformations.

When working with data, transformations become really important because you often need to:

change data formats
calculate values
clean data
combine text
or prepare data for analysis

Sometimes a number is stored as text and needs to be converted.
Sometimes data contains unwanted values or formatting that needs to be cleaned up.

So I wrote an article explaining:

how SQL transformations work
simple practical examples
and common beginner use cases

I also added a small SQL Formula Sheet at the end 😊

As someone still learning SQL myself, I tried to explain things in a very simple and practical way instead of making it overly technical.

If you are currently learning SQL, maybe this will help you 😊

I recently wrote a beginner-friendly article about SQL filtering / WHERE clauses.

When I started learning SQL, I mixed a lot of things up, forgot NULL values, missed brackets, and sometimes got completely wrong results without understanding why.

So I wrote an article explaining:

how filtering actually works
common beginner mistakes
simple real-world examples

I also added a small SQL Formula Sheet with filtering functions at the end.
