SQL error: foreign key constraint fails

"Cannot add or update a child row: a foreign key constraint fails...."

Example of the error

This is a common issue with some QBCore installations. The way we set up job garages, we update the citizenid and set it to the name of the job. Some installations prevent this due to a database constraint.

Fixing this issue is simple, just remove the constraint. Run the following SQL in your database:

ALTER TABLE player_vehicles DROP FOREIGN KEY FK_playervehicles_players

Some databases might use another name than the "FK_playervehicles_players" so make sure you change it to the one showing in your error

Example of another foreign key name

In this example the foreign key name is player_vehicles_ibfk_1 so the sql query will look like this:

ALTER TABLE player_vehicles DROP FOREIGN KEY player_vehicles_ibfk_1
