Title: My co-worker and I were debugging a SQL issue; having not seen SQL in two years, I embarrassed myself by confusing union vs. join. After this episode, I tried refreshing my SQL memory, but there are few websites that animate SQL for you. Most of them just have a series of images to help you visualize. There are a few tools that are quite good and robust (especially for large&#x2F;complex use cases) but require installation and are too complex for my simple purpose.<p>So, just created a small tool to help visualise SQL. Most of the animations are just my understanding of how SQL works. Would love to know what you think? Do you also visualise some of the queries like that in your head? Any feedback would be gold. Btw you can also edit queries and see different results (but its a bit limited).<p>Have fun ;)
