I'm trying to use logical operators with CASE / WHEN in SQL but I'm having difficulties, I need to give a response in case the result of the operation is less than 0 and another result for when the operation is > = 0
It makes a mistake if I put a logical operator there:
CASE (A + B + C)
**WHEN >= 0** THEN 'RESPOSTA'
ELSE 'SEM RESPOSTA'
END AS RESULTADO
