Why should you care?

The ability to compose queries and extract insights from production data is an invaluable skill.

Knowing SQL is powerful.

Being able to quickly write queries, glean insights from production and generate organized CSVs make you helpful. SQL gets the job done and others can depend on you.

SQL is a core developer skill.

Regardless of databases or SQL flavours or database your company uses, it's an incredible skill to be able to write queries and get results back within seconds.

SQL as a career booster.

At some point, you need to get data out of relational databases. You don't want to always talk to senior engineer or DBA to troubleshoot data issues, or filter error logs. Once you gain SQL fluency, it follows you from job to job.

It's a technology that lasts

SQL isn's the trendiest, and is often overlooked. Over the last decades, it has outlasted VBScript, VBA, Java, C#, Javascript, Typescript and Python, and will do many more in the foreseeable future.
