Description
Returns the rank of the current row if ordered by the given argument. Rows corresponding to the same value used for sorting have the same rank. If the first two rows both have rank of 1, then the next row (if it features a different value) will have rank 3, so, in effect, it is rank with gaps.
If direction is "desc" or omitted, then ranking is done from greatest to least, if "asc", then from least to greatest.
See also RANK_DENSE, RANK_UNIQUE, RANK_PERCENTILE.
Argument types:
value—Boolean | Date | Datetime | Fractional number | Integer | String | UUIDdirection—String
Return type: Integer
Note
Only constant values are accepted for the arguments (direction).
