For the past couple of weeks, I have been writing a lot of SQL queries as we do a major data update of the db. The update has been fairly painful, requiring a couple of days of manual mapping of old and new data. But what I realized over the last couple of weeks is that I have forgotten SQL and badly.
Before I dove into the world of startups, I worked at Tesco HSC and I spent a lot of time over there writing SQL queries. Over the years I had become pretty good at it and had learnt some neat tricks such as using a pivot function. The reports I had developed required some complex data processing which meant a lot of temporary tables and a lot of complex sql queries, all while maintaining acceptable execution time.
But three years later, I seem to have forgotten SQL. I feel my current proficiency in SQL has gone down from intermediate to beginner. But then I think that three years ago, I sucked at CSS and Javascript. I have been spending more time on front end stuff over the last year than back end. Also, I guess the back end stuff that I have had to touch has been fairly simple. So I guess it's OK.
But it certainly isn't nice to feel that you are losing touch! :(
