element_at 元素在集合中查找 select element_at((select collect_list(id) col from data),int(id)) from data ; filter 过滤 SELECT filter(array(1, 2, 3), x -> x % 2 == 1);[1,3] slice 数组切数组 SELECT slice(array(1, 2, 3, 4), 2, 5);[2,3,4] transform 数组元素map SELEC...
从源码里看到,array相关函数主要分为四类: array_funcs(一般的array函数,比如取最大、最小、包含、切片等) collection_funcs(集合类的操作,比如数组求size、反转、拼接等) map_funcs(从map结构中衍生出来的函数,比如element_at) lambda_funcs(这几种函数中当属lambda_funcs最骚气,学起来会比较难,但可真是太灵活...
Returns element of array at given index invalueif column is array. Returns value for the given key invalueif column is map. C# [Microsoft.Spark.Since("2.4.0")]publicstaticMicrosoft.Spark.Sql.ColumnElementAt(Microsoft.Spark.Sql.Column column,objectvalue); ...
调用通过 SparkSession.Udf () 注册的用户定义函数。Register () 。 Cbrt(Column) 计算给定列的多维数据集根。 Cbrt(String) 计算给定列的多维数据集根。 Ceil(Column) 计算给定值的上限。 Ceil(String) 计算给定值的上限。 Coalesce(Column[]) 返回不为 null 的第一列;如果所有输入均为 null,则返回 null。
