Creating complex select queries
SQL is used by most relational database management systems (RDBMS) to manage tabular data. It is a fundamental skill expected from data scientists and analysts.
You might argue that it is the job of a data engineer but the data scientist roles are inclined to being full-stack. Besides, as a data scientist, you wouldn’t want to depend on a data engineer to retrieve data from a database.
Long story short, having SQL in your skill set will put you one step ahead in searching and securing a job in the field of data science.
In this article, we will go over 6 select query examples. Although most of the SQL syntax is same among different relational database management systems, there might be some small differences. We will be using MySQL in this article.
