Merriam Webster Dictionary defines ‘Sample’ as “a small amount of something that is given to people to try” and that is exactly what the SAMPLE database that is shipped along with every IBM’s DB2 LUW installation is. This database has objects that reflect a real world like data model along with sample data. It could be a nice play ground for someone who is looking to experiment with or to learn new features in DB2 LUW.
In this blog post, we will look at how simple it is to create this sample database. We will also look at what this database has to offer to us.
Although awk and awkward start with the same three letters, awk by no means is awkward. Well, from the syntax of it (and I agree, sometimes, from its learning curve), it could be appear to be so. In this blog post, I share how awk’s most basic features could be powerful tools to get things done faster.
I use awk in many of my UNIX scripts that I write to automate routine tasks. In addition to this, I routinely write awk one-liners to save time. Many times, these one-liners are throw-away in that the same exact awk command might not be used again.
Handling tables (or other database objects) that have mixed case names and/or with special character(s) in their names needs special effort. In this blog post, we will look at our options; essentially, what works and what does not work.
It is no wonder that I cannot live without awk even a single (working) day in my life. Such is the power of awk (or AWK). It is simply the most powerful utility that I use on *IX (Linux/AIX) systems. awk makes my life easy when dealing with daily DBA tasks. I learned awk almost 10 years ago and I admit that it was tough to get used to its syntax. However, once I knew few basics, it was fun.
