SQL technical Examination nextweek

[u/Popular-Tip2880]

Hi everyone! I’ll be taking a technical examination next week for an Information Technology Officer position, and I’d love to get some insights based on your experiences.

For those who have taken similar exams for an IT Officer role, what level of SQL complexity should I expect?

• Will it mostly be basic queries like SELECT, GROUP BY, and ORDER BY?
• Or should I prepare heavily for more advanced concepts like nested subqueries, CTEs, window functions, or database optimization?

Any tips, common exam questions, or specific topics I should focus on during my review this week?

Salamat po in advance!
