I am encountering an issue with Laravel’s query builder. I have a query that uses a where clause to compare a column against a value using either != or !==. The query works locally, but after pushing the code to the repository and deploying it to the live server, it sometimes fails.

$query->where(‘column_name’, ‘!=’, $value);

When I change the operator to !==, it works locally but fails on the live server after deployment:

$query->where(‘column_name’, ‘!==’, $value);

The behavior is inconsistent. Sometimes != works, and other times !== works. I can’t determine why this inconsistency occurs and how to resolve it permanently.
