I’m trying to get comfortable with sql, procedures and functions. Can you guys recommend anything?
One approach is to use https://www.db-fiddle.com/ or similar fiddle web sites. They’re especially handy if you want to try things on different makes and models of database server. But you can’t use them to handle more than a small amount of data.
Another approach (better in my opinion) is to download and run a free development version of a database server. All the majors have development versions.
Find yourself some nice open (freely-available) data to play around with. The easiest format to import into SQL is “csv” Read this FCC article for some pointers.
Here’s some timely data: The New York Times newspaper’s pandemic statistics. It’s in csv format, so it’s fairly straightforward to import into your own database server.
Keep this in mind: the language for stored procedures and stored functions varies, a lot, between makes of database server.
Great advice thank you!
you can find SQL between the languages available at codewars too: https://www.codewars.com/
