How to Search for Emails within a JSON Array in Laravel\'s \'To\' Column?

Searching JSON Columns in Laravel

When working with JSON columns in Laravel, searching for specific values can be challenging. Here's a solution to the frequently encountered issue of locating emails within a JSON array stored in a "To" column.

The Problem:

In an "emails" table, a "To" column of type JSON contains nested arrays representing email addresses. The goal is to retrieve a collection of all emails sent to a particular recipient.

Failed Attempt:

An initial attempt to search using Laravel's whereJsonContains method resulted in no matches. The query "translated" as:

select * from `emails` where json_contains(`to`->'$."emailAddress"."address"', '\"[email protected]\"'))

Solution:

The key to a successful search lies in understanding that the arrow operator (->) does not work with arrays. For JSON searches involving arrays, use the following syntax:

DB::table('emails')
   ->whereJsonContains('to', [['emailAddress' => ['address' => '[email protected]']]])
   ->get()

This query will correctly identify and return all emails sent to the specified recipient's address.
