COUNT — peek at the supplier dim and produce a single scalar.

The Brief

Maya ChenOps Directorslack-dm

Welcome aboard. Before our supplier review on Friday, just give me a head-count: how many suppliers are in `dim_suppliers`? One number. Nothing fancy.

Hints (3)

Each hint you reveal reduces the XP you can earn. Try the query first.

Hint 1

There's exactly one table you need: `dim_suppliers`.

Hint 2

Maya wants a count, not the rows themselves. Reach for `COUNT(*)`.

Hint 3

The full query is `SELECT COUNT(*) FROM dim_suppliers`. One column, one row.
