A little different from my posts about learning Python and how I learned R.
This is kind of the third article I am publishing about "How I learned" stuff and especially "Data languages".
The story behind the learning
The story behind the "Why did I learn SQL" is kind of funny: at the time still working as a Data Analyst in Luxembourg, I was creating reports with Power BI and we were building out data platform, so I took my chance and participated.
I knew very little about engineering or coding languages ... but I was curious and eager to learn.
Following that I learn the "simple".
SELECT *
FROM data_base_name
LIMIT 10
The second real article about SQL
This is my second article about SQL on this blog, the first one was SQL 101 where I added some useful tips I learned along the way working with SQL. Yes, my SQL 101 is simple, but it's a introduction and some tips 😇
SQL is used everywhere
I am not joking, I realized that using SQL helped me better understand lots of things and I could use what I learned on a lot of things:
- Inside the
QUERY()formula of Google Spreadsheet - Connecting Google Big Query to Google Spreadsheet
- Being able to look at data by myself and dig a little bit
- Doing quick analysis, extractions & table to present to people
