Have a SQL interview with another e-commerce company tomorrow for a data analyst role. Wonder if leetcode is enough for this kind of role?

    SQL topics to focus on
    1. Group By ( aggregation)
    2. Where vs having clause
    3. Inner and outer joins
    4. Union vs union all
    5. Nulls , and how they affect your queries
    6. Sub query, depends on your experience and their requirements
    7. Case statements

    Good luck OP. Please let us know how it goes and also what kinda questions they asked.

    I see all suggestions above related to basic SQL. In a data analyst role, you’ll often require window functions and will be tested on that.
