My most recent Quizletter featured a quiz on ORDER BY in TSQL, complete with questions on the OFFSET and FETCH clauses which we got in SQL Server 2012.
One great thing about teaching TSQL School is that it reminds me of these cool options that can be easy to forget.
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 how tricksy AVG() can be.
