SQL reporting engineer

Learn selection and joins, define trustworthy reports, then use windows and cursor pagination.

Your goal

Deliver a report with clear row grain, tests for NULL and ties, and an inspected execution plan.

Use each checkpoint as evidence: solve an exercise without the solution open, explain its edge cases, and revisit a failed concept the next day. Course completion records practice; it is not an accredited qualification.
