Bring Your SQL To The Next Level

When you start learning SQL and databases it is trivial to find good resources. My adventures started with ORACLE8i The Complete Reference. Tutorials are another way. With the official documentation for your RDBMS on hand you can learn the specific dialect of SQL you need. Later in your career you might cross the way of an SQL guru. In that point in time you wonder: How can I reach that level? I met quite a few over the years. Questions for recommendations stay often unanswered. Those guys breath SQL day in and day out. Most of their tricks they learned by practice. After some time consuming research I found a few books which brought me to the next level.

I often hear complains about the age of some books. To be honest with you: The mantra that the computer world is a fast changing one is a lie. Yes. There are a lot of moving targets. But we have a lot of technologies which are only changing slowly if at all. At least if you don’t look under the hood. UNIX, Linux, protocols like SNMP, HTTP, programming languages. A lot of tools are around for more than 20 years. So even from a book written 10 or more years ago you can learn a lot.

But let’s go through my list! In the beginning you need recipies for the problems in front of you. Don’t look further than the SQL Cookbook. Over 600 pages for most of your daily problems. I use it on a regular basis to solve the problem i have right now. SQL is just one side gick for me and my memory is not very good. No shame for using it side by side with your editor or SQL frontend.

As human beeings we tend to make all the same mistakes. To avoid some of them read SQL Antipatterns: Avoiding the Pitfalls of Database Programming. With 329 pages it wont take much time but will give you time back with the lessons learned.

More lessons with a practical background you will find in The Art of SQL. 370 pages giving you lots of thoughts. I am the first to admit that I had to read a few pages twice. Probably not a bed time lecture if you want to learn from it.

If you know a book missing in this list feel free to contact me. And always keep in mind: Some SQL statements are written in a day and not a minute. If they run often, are fast and deliver the right result it is well spend working time.
