Oracle SQL Best Practices Guide

How To Optimise and Improve Your Code Even If You Don't Have Database Administrator Privileges

You don't need to spend time analysing log files or worry about writing SQL queries the wrong way any more.

When I started my career as an Oracle developer, I made many mistakes. I wrote slow code, used incorrect syntax, and almost crashed a production server!

Luckily I had more senior developers in the team who were able to educate me. But it took time.

I wasn't aware of the best way to write Oracle SQL queries.

I didn't know about any "best practices", or things to avoid.

But, now I do.

There are some ways of writing SQL which will get you the result you need, but there are other ways you can write the query to get you the same result in a much more efficient way.

I've created a guide to these best practices. A guide that shows the best way to write and structure your queries to avoid these kinds of issues.

You no longer have to think about what the best way is to write a certain query. You can follow these best practices to rewrite your queries, check if there is a performance gain, and implement them.

You don't have to look at messy and inconsistent code again, if you develop based on a consistent set of formatting rules, such as the ones I've included in this guide.

This guide can be put into action right away.

I've included actionable information for over 30 best practices. I explain:

• what the tip is
  
• why its advisable to follow
  
• an example where this tip isn't followed
  
• an example where the tip is followed
  

All in a single PDF file.

Imagine having a single file that you can refer to whenever you're writing SQL, to ensure that you're writing the most efficient query you can be.

Imagine the time you'll save when writing the query, when you know the different approaches you can take, and which one is generally better.

Imagine the improvements in run time when you start changing your queries to be more efficient.

Why this guide?

I've scoured the Internet for a wide range of best practices that are widely used and current (not just from a single outdated website!)

I've spoken with co-workers who use Oracle on a daily basis.

I've also considered my own experience with Oracle and things I learnt while achieving my Oracle SQL Expert certification.

I'd like to present...
