My personal battle with SQL
Is it pronounced ‘Es queue el’ or ‘See quell’? I still have no idea.
What I do know is that I’m glad I took the time to learn some SQL (Structured Query Language).
I was initially retrieving masses of data then performing some really complex maths in php before discovering that most of what I was doing could be calculated directly within the select statement. Averages and percentages for example. SQL website was a saviour here although some of the solutions had me baffled, especially ranking for the leaderboards.

I'm still working my way through the brilliant tutorials at W3Schools.
Even though I only know a tiny fraction of what SQL is capable of, it is probably the most satisfying of all the languages I’ve learnt. That feeling when you run a select statement and it gives exactly the result you wanted is very hard to beat. Sad I know, but so true.
