pyspark.sql.functions.array_remove (col: ColumnOrName, element: Any) → pyspark.sql.column.Column [source] ¶ Collection function: Remove all elements that equal to element from the given array. New in version 2.4.0.
Jan 12, 2019 · Spark 2.4 introduced new useful Spark SQL functions involving arrays, but I was a little bit puzzled when I found out that the result of select array_remove(array(1, 2, 3, null, 3), null) is null and not [1, 2, 3, 3]. Is this the expected behavior? Is it possible to remove nulls using array_remove?

Function array_contains() in Spark returns true if the array contains the specified value. Returns null value if the array itself is null; otherwise, it returns false. This is primarily used to filter rows from the DataFrame. Syntax The following example returns the DataFrame df3by including only rows where the list column “languages_school” contai...
array_sort() function arranges the input array in ascending order. The elements within the array must be sortable. When you have NaN values in an array, the following applies. 1. For double/float type, NaN is considered greater than any non-NaN elements. 2. Null elements are positioned at the end of the resulting array. Syntax Example From the code...
This function combines all elements of the list/array column using the delimiter. When the nullReplacementparameter is used, the array containing null values is replaced with ‘nullReplacement’. Syntax Example This example creates a new DataFrame df4 based on the DataFrame df. In this new DataFrame, a new column named “array_join” is added. This col...
array_append() function returns an array that includes all elements from the original array along with the new element. The new element or column is positioned at the end of the array. Syntax Example it returns a new DataFrameby adding a new column named “array_append”. This column contains arrays that include all the elements from the original “la...
Similarly, the array_unionfunction combines the elements from both columns, removing duplicates, and returns an array that contains all unique elements from both input arrays. If there are any null arrays or columns, they are ignored in the union operation. Syntax Example In this new DataFrame, a new column named “array_union” is added. This column...
The array_size() returns the total number of elements in the array column. If your input array column is null, it returns null. Syntax Example This returns a new DataFrame with a column containing the array size of the column languages_school
Use array_position() to find the position of the first occurrence of the value in the given array. It returns null if either of the arguments is null. Note that the position is not zero-based but 1 1-based index. Returns 0 if the value could not be found in the array. Syntax Example
In Spark, array_insert() is a function used to insert elements into an array at the specified index. You can use array_insert()in various scenarios where you need to modify arrays dynamically. Syntax
arrays_overlap() It evaluates to true when there’s at least one non-null element common on both arrays. If both arrays are non-empty but any of them contains a null, it yields null. Otherwise, it returns false. Syntax
In Spark, the array_distinct()function is used to return an array with distinct elements from the input array. It removes duplicate elements and returns only unique elements in the resulting array. Syntax The function returns a new array containing only distinct elements from the input array, preserving the original order of elements.
Dec 27, 2023 · The array_remove () function allows removing a specific element from array columns across all rows in the DataFrame. The syntax is: array_remove (col, value) Where: col – Name of array column. value – Element to remove. For example: from pyspark.sql.functions import array_remove df2 = df.withColumn ("names", array_remove (df.names, "John"))
