从哪里选择SQLite表的随机行？

Question

我有这样一个表：

CREATE TABLE records (_id INTEGER PRIMARY KEY, 
        question TEXT, answer TEXT, category INTEGER) 

给予一个特定的类别值（假设2），我要选择从该类别排随机。这就是我想象的解决方案：

Select question, answer, category //I think there is something missing 
From  records 
Where category=2 

任何帮助将不胜感激！

Answer 1

你可以把它像：

SELECT question, answer, category 
FROM records 
WHERE category=2 ORDER BY RANDOM() LIMIT 1;
