	// #### Purpose

	// The purpose of this query is to update the `purchase_price_in_eur` field in
	// the `project-id.firestore_stream.payments_revenuecat_daily_exports` table.
	// The `purchase_price_in_eur` is calculated based on the `purchase_price_in_usd` and
	// the most recent EUR to USD exchange rate available in the `historical_eur_to_usd`
	// table. If the exchange rate for a specific date is not present, the query uses the
	// most recent available exchange rate before that date.
