What it does
SQL Police Department teaches query work through mission briefs, database results and an integrated SQL guide.
Read the mission brief before constructing a query, then use the returned values to complete the investigation. The interface includes SQL fragments and a guide, providing help while you work through a case. This setting is useful for practising how a question translates into filters and table operations. A few cases are offered to try before buying a licence. Paid access is described as time-limited, so read the current duration terms before purchasing rather than treating the licence as permanent ownership.
