我们会帮你做转换，而不是从头开始为你写。看到这个指导元：http://meta.stackoverflow.com/questions/333952/why-should-i-provide-an-mcve-for-what-seems-to-me-to-be-a-very-简单的SQL查询 – 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分区，和我上面的查询试图为相同的，我竟要被输出，当我上面的查询集成到主查询它抛出错误
