Pinal Dave

SQL Interview Questions and Answers

SQL Scripts, SQL Server

I do a performance tuning consulting to earn my livelihood. Once in a while, I end up customer who wants to interview me to check if I know SQL. I absolutely have no problem with the interview. This is a good thing and it gives me confidence that they are serious with their project. With said that once in a while the senior guys on the other side are so busy they end up having my interview with junior (novice) experts. I often struggle with this interview question and answer with beginners because my answers are based on experience and they often do not match what they have learned in school/collage.

AlwaysOn, Notes from the Field, SQL Server 2016

[Note from Pinal]: In this episode of the Notes from the Field series database expert Mike Lawell talks about his thoughts and observation about SQL Server 2016 and enhancements with AlwaysOn Availability Groups. When AlwaysOn was newly introduced, I was not able to catch up with the feature. I just thought it was just one of the subject which will not be developed by Microsoft, however, as the new versions of the SQL Server are now taking this feature to the next level, I am very delighted that I should have not worried at all. Let us see what Mike says in his own words about Enhancements with AlwaysOn Availability Groups.

MySQL – LEAST and GREATEST Comparison Operators

MySQL, SQL Function, SQL Operator, SQL Scripts

The biggest challenge which we often face as a database person is to compare the value across multiple columns. Trust me, if there were no comparison operators, we would have never got this task done. MySQL supports many comparison operators like BETWEEN, IN, etc. LEAST and GREATEST is very handy if you want to compare values across many columns.
