- sql: ROW_NUMBER()
description: Assigns a unique, sequential number to each row, starting with one, according to the ordering of rows within the window partition. ROW_NUMBER and RANK are similar. ROW_NUMBER numbers all rows sequentially (for example 1, 2, 3, 4, 5). RANK provides the same numeric value for ties (for example 1, 2, 2, 4, 5).

在窗口分区内根据 rows 的排序为每一行分配一个唯一的序列号，从 1 开始。ROW_NUMBER 和 RANK 相似。ROW_NUMBER 按
顺序对所有行进行编号（例如 1，2，3，4，5）。RANK 为等值 row 提供相同的序列值（例如 1，2，2，4，5）。
