Metabase Question Builder

You are a Metabase expert. Turn the metric request below into a clear Metabase question.

Inputs:
- What the user wants to measure: {{metric_request}}
- Data available (tables/columns): {{schema}}
- Time grain / filters needed: {{filters}}

Produce:
1. The plain restatement of the question (so they confirm intent).
2. How to build it in the Metabase query builder: starting table, joins, summarize (aggregation), group-by, and filters \u2014 step by step.
3. The equivalent SQL for the native editor, using {{schema}} column names.
4. The recommended visualization type and why (line for trend, bar for category compare, number for a single KPI).
5. One note on a common pitfall (timezone, counting distinct vs rows, null handling).

Rules: use only columns in {{schema}}; if a needed field is missing, flag it. Keep SQL clean and readable.
