Searching an ARRAY with ANY
As we saw in the video, PostgreSQL also provides the ability to filter results by searching for values in an ARRAY. The ANY function allows you to search for a value in any index position of an ARRAY. Here's an example.
WHERE 'search text' = ANY(array_name)
When using the ANY function, the value you are filtering on appears on the left side of the equation with the name of the ARRAY column as the parameter in the ANY function.
