PostgreSQL – ARRAY_REMOVE Function

ByAdmin

The array_remove function in PostgreSQL is used to remove all occurrences of a specified value from an array. It takes two arguments: the array from which you want to remove elements and the value you want to remove.

Below is the syntax of the array_remove function:

array_remove(array, value_to_remove)

Where:

array is the array from which you want to remove elements.

value_to_remove is the value you want to remove from the array.

Here’s an example of using the array_remove function:

SELECT array_remove('{10, 20, 30, 40, 20}', 20) AS result_array;

The output would be:

result_array 
-------------- 
{10,30,40} 
(1 row)

In this example, the array_remove function removed all occurrences of the value 20 from the input array.
