Mysql SQL显示多列

我想做的是展示亚洲和欧洲国家的所有信息，而不是其他大陆的信息。然后按大陆订购。我只是错过了一些明显的东西，但那是什么

如果我把和放在亚洲和欧洲之间，那么它将试图显示来自亚洲和欧洲的国家，所以这不起作用，但如果我把放在亚洲和欧洲之间，那么它将只显示亚洲

我的代码是什么样子的

SELECT * 
FROM country
WHERE Continent = 'Asia' AND 'Europe'
ORDER BY Continent DESC;

试着跟随

SELECT * FROM country
WHERE Continent in ('Asia','Europe')
ORDER BY Continent DESC;

试一试

或

试试这个

SELECT * FROM country
WHERE Continent In( 'Asia' , 'Europe')
ORDER BY Continent DESC;

（或）

万一你想要非非洲人和澳大利亚人

SELECT *
FROM country
WHERE !(Continent = "Africa" AND Continent = "Australia") 
ORDER BY Continent DESC;

谢谢，伙计。很好，我理解我现在做错了什么。解决了，谢谢大家。世界上有四大洲。

SELECT * FROM country
WHERE Continent = 'Asia' OR Continent = 'Europe'
ORDER BY Continent DESC;

SELECT * FROM country
WHERE Continent In( 'Asia' , 'Europe')
ORDER BY Continent DESC;

SELECT * FROM country
WHERE Continent ='Asia' OR Continent= 'Europe'
ORDER BY Continent DESC;

SELECT * FROM country
WHERE Continent ='Asia'
ORDER BY Continent DESC;
UNION ALL
SELECT * FROM country
WHERE Continent ='Europe'
ORDER BY Continent DESC;

SELECT *
FROM country
WHERE Continent = "Africa" OR Continent = "Australia"
ORDER BY Continent DESC; 

SELECT *
FROM country
WHERE !(Continent = "Africa" AND Continent = "Australia") 
ORDER BY Continent DESC;
