Spark url extractor11/1/2022 ) - Returns an array with the given elements.Īrray_contains(array, value) - Returns true if the array contains the value.Įxamples: > SELECT array_contains(array(1, 2, 3), 2) Īscii(str) - Returns the numeric value of the first character of str.Īsin(expr) - Returns the inverse sine (a.k.a. In this case, returns the approximate percentile array of column col at the givenĮxamples: > SELECT approx_percentile(10.0, array(0.5, 0.4, 0.1), 100) When percentage is an array, each value of the percentage array must be between 0.0 and 1.0. Higher value of accuracy yieldsīetter accuracy, 1.0/accuracy is the relative error of the approximation. The accuracy parameter (default: 10000) is a positive numeric literal whichĬontrols approximation accuracy at the cost of memory. The value of percentage must be between 0.0Īnd 1.0. RelativeSD defines the maximum estimation error allowed.Īpprox_percentile(col, percentage ) - Returns the approximate percentile value of numericĬolumn col at the given percentage. arccosine) of expr if -1 SELECT acos(1) Īdd_months(start_date, num_months) - Returns the date that is num_months after start_date.Īpprox_count_distinct(expr) - Returns the estimated cardinality by HyperLogLog++. > SELECT to_date(' 04:17:52') >= to_date(' 04:17:52') Įxpr1 ^ expr2 - Returns the result of bitwise exclusive OR of expr1 and expr2.Ībs(expr) - Returns the absolute value of the numeric value.Īcos(expr) - Returns the inverse cosine (a.k.a. > SELECT to_date(' 04:17:52') > to_date(' 04:17:52') Įxpr1 >= expr2 - Returns true if expr1 is greater than or equal to expr2. For complex types such array/struct, the data types of fields must For example, map type is not orderable, so it Map type is not supported.įor complex types such array/struct, the data types of fields must be orderable.Įxpr1 = expr2 - Returns true if expr1 equals expr2, or false otherwise.Įxpr1 > expr2 - Returns true if expr1 is greater than expr2.Īnd must be a type that can be ordered.
