RANK

Returns the rank of the current row within its partition and placement order. Rows that are equal have the same rank. However, the count of tied rows is added to the next rank, instead of being incremented by one. The rank value starts at 1 and increases sequentially.

Syntax

RANK() OVER ( [PARTITION BY partition_expression][ORDER BY order_expression]) → bigint

  • partition_expression (optional): An expression that groups rows into partitions.
  • order_expression: An expression that specifies the order of the rows within each partition.
