The LIKE operator is a very useful one. It is used to match strings with partial match while using the underscore (‘_’) as a single character wildcard and the percentage sign (‘%’) as multiple character wildcard.
In February ’17 I participated in Mike Dietrich’s upgrade workshop and it was great! I don’t want to repeat stuff that he said there, you can read everything on his blog. This workshop made me think about upgrades I did in the past (and I did quite a few) and important things to think about before and after upgrading a database.
One of my customers is working with ASM and their database grows really fast. So every one in a while we need to add another ASM disk to the system.
When I open Oracle documentation to look for something, people usually raise their eyebrows (almost as they do when I open sqlplus). Most of them simply say: “What do you need the documentation for? Just open google and search”. Even though googling stuff usually works, I actually like the documentation (in some aspects at least).
I ran into this post on Linkedin talking about what non-Israeli people should expect when working with Israelis (and especially if they visit Israel for business). It’s a very nice read and it’s not long. After reading it (and laughing to myself, as it’s quite accurate), I decided to write this post. Most of the people that read my blog are spread around the world, and the culture difference between countries is truly interesting.
