我們會幫你做轉換，而不是從頭開始爲你寫。看到這個指導元：http://meta.stackoverflow.com/questions/333952/why-should-i-provide-an-mcve-for-what-seems-to-me-to-be-a-very-簡單的SQL查詢 – Shadow

SELECT @row_number：= CASE WHEN = @customer_no THEN customer_ship_to @row_number + 1 ELSE END AS NUM， @customer_no：= customer_ship_to如customer_ship_to， SALES_ORGANIZATION， id_promotion FROM customer_ship_to_promotions，（SELECT @customer_no：= 0，@ row_number：= 0）as t ORDER BY customer_ship_to;

我被卡在ROW_NUMBER分區，和我上面的查詢試圖爲相同的，我竟要被輸出，當我上面的查詢集成到主查詢它拋出錯誤
