mysql - SQL Select 语句限制和描述顺序

Question

只需要有人告诉我这个语句是否有正确的语法；我无法让它正常工作。

SELECT plantname, orderfreq, totalincome 
FROM plantreview 
WHERE score >='5' 
AND recommended='1' 
ORDER BY score DESC, LIMIT +0, 5

Answer 1

假设 MySQL，在or,之后不应该有. 如果您的列是整数，则也不需要将其括在引号中。ORDER BY+LIMIT

SELECT plantname, orderfreq, totalincome 
FROM plantreview 
WHERE score >='5' 
AND recommended='1' 
ORDER BY score DESC
LIMIT 0, 5

看到它在行动
