Ranking functions return a ranking value for each row in a partition. All the ranking functions are non-deterministic. Each of the ranking functions also needs the OVER( ) clause.<\/p>\n
The different ranking functions are as follows:<\/p>\n
ROW_NUMBER () OVER ([ ]<\/em><\/strong><\/p>\n <order_by_clause>)<\/em><\/strong><\/p>\n Returns the sequential number of a row within a partition of a result set, starting at 1 for the first row in each partition.<\/p>\n RANK () OVER ([ ] <order_by_clause>)<\/em><\/strong><\/p>\n Returns the rank of each row within the partition of a result set. After a tie there will numeric gaps in the next ranked<\/p>\n number.<\/p>\n DENSE_RANK () OVER ([ ]<\/em><\/strong><\/p>\n <order_by_clause>)<\/em><\/strong><\/p>\n Returns the rank of rows within the partition of a result set, without any gaps in the ranking.<\/p>\n NTILE (integer_expression) OVER ([ ]<\/em><\/strong><\/p>\n <order_by_clause>)<\/em><\/strong><\/p>\n Distributes the rows in an ordered partition into a specified number of groups.<\/p>\n Thanks \u00a0for reading \u00a0this \u00a0article,<\/strong><\/p>\n Next steps :<\/strong><\/p>\n 1.\u00a0<\/strong>Share this with your colleagues because Sharing\u00a0 is Learning<\/strong><\/p>\n \u00a0 \u00a0 \u00a0 \u00a02.
