How to select rows containing a specific JSON column key, regardless of the value. All in Laravel and MySQL

I wrote this code in Laravel 10:

$unit = Unit::whereJsonContains('prefixes->abc', 'cba')->first();

and I got this query:

`select * from `units` where json_contains(`prefixes`, '\"cba\"', '$."abc"') limit 1`

I have a row in the database that contains {"abc":"cba","cde":100} JSON in the ‘prefixes’ column. My code works fine – it selects the correct row from the database.
I want to select a row that contains a key named "abc" regardless of the value of that key. I can’t achieve this. I thought to make a selection like:

`select * from `units` where json_contains(`prefixes`, '%', '$."abc"') limit 1`

but that doesn’t work in phpadmin (it doesn’t select anything).

I have not been able to get the right query through either Laravel Eloquent or raw SQL selection.

What should I do in Laravel and what should the SQL querry look like?

>Solution :

JSON_CONTAINS_PATH would do the trick, e.g.

select * from `units` where json_contains_path(`prefixes`, 'one', '$."abc"') limit 1
