Top Interview Questions & Answers
Q1: What is the difference between RANK(), DENSE_RANK(), and ROW_NUMBER() in SQL?
ROW_NUMBER assigns a unique sequential integer to each row. RANK assigns identical numbers for tied values but skips subsequent numbers (e.g. 1, 2, 2, 4). DENSE_RANK does not skip ranks on ties (e.g. 1, 2, 2, 3).
Q2: Explain the CALCULATE function in Power BI DAX with an example.
CALCULATE evaluates an expression in a modified filter context. Example: CALCULATE(SUM(Sales[Amount]), Region[Country] = "India") calculates total sales specifically filtered for India.
