摘要： 语法：ROW_NUMBER() OVER(PARTITION BY COLUMN ORDER BY COLUMN)简单的说row_number()从1开始，为每一条分组记录返回一个数字，这里的ROW_NUMBER() OVER (ORDER BY xlh DESC) 是先把xlh列降序，再为降序以后的没条xlh记录返回一个序号。示例：xlh row_num1700 11500 21085 3710 4row_number() OVER (PARTITION BY COL1 ORDER BY COL2)表示根据COL1分组，在分组内部根据 COL2排序，而此函数计算的值就表示每组内部排序后的顺序 阅读全文
