Answer 1

SELECT
CASE Class 
WHEN 25 THEN 'good'
WHEN 145 THEN 'very good'
END AS translatedNumbers
FROM yourTable

Answer 2

你需要类似的东西：

SELECT name,
       IF(class=25,"Good",IF(class(145,"Verygood",class)) AS display 
FROM yourtable

或者您可以使用case：

SELECT name,
     CASE class 
         WHEN 25 THEN "Good" 
         WHEN 125 THEN "Verygood"
         ELSE class 
     END AS display 
FROM yourtable
