Data Analyst Associate: practice questions
SQL edge cases decide this exam: nulls in aggregates, window frames, and the rules that make two reasonable-looking queries return different numbers.

Data Analyst Associate set
12 questions, drawn fresh from the bank. Every code question was executed on Spark before it shipped, and each answer links to the documentation it rests on.

A sample question, with the answer
A column has values 10, NULL, and 20. What do COUNT(*) and COUNT(col) return?
- a3 and 3
- b3 and 2correct
- c2 and 2
- d3 and NULL
Why: COUNT(*) counts rows; COUNT(col) counts non-null values of that column. Mixing the two inside one report is a classic source of numbers that almost match.
