AVG And Data Types

Kendra Little explains how the AVG() function works with a couple different data types:

This week’s Quizletter featured a quiz on using the AVG() function in SQL Server.

I was inspired to write this quiz because I’ve been teaching TSQL School each week. When we covered aggregate functions, I remembered just how tricksy and non-average that AVG() can be.

Want to take the quiz before you read the answers?

Head over here and take the quiz first.

Or read this post and then take the quiz, if you prefer. I’m not gonna call it cheating, because it’s learning either way.

Kendra explains each of the answers, so I’d recommend taking the quiz first.
