I have a problem in the MySQL Query:
How can i SELECT something but when it errors because it doesn´t exist it should return a value like 1 or something else.
My Query
SELECT License FROM fivem_auth WHERE IP = '34.45.34.77';
You can UNION
your query with a query that returns the default if the row doesn't exist.
SELECT License FROM fivem_auth WHERE IP = '34.45.34.77'
UNION ALL
SELECT 1 FROM DUAL
WHERE NOT EXISTS (SELECT 1 FROM fivem_auth WHERE IP = '34.45.34.77')
