从条件

Question

我有mysql数据库60k行，4列（ID，关键字，状态，Updet）并尝试使用此选择快速rand：

SELECT Keyword 
FROM keyword AS r1 
JOIN (
    SELECT CEIL(RAND() *(SELECT MAX(id) FROM keyword)) AS id
) AS r2 
WHERE r1.id >= r2.id 
ORDER BY r1.id ASC LIMIT 1

但问题是我无法选择条件Updet =＆＃39;已发布＆＃39;并尝试

SELECT Keyword 
FROM keyword AS r1 
JOIN (
    SELECT CEIL(RAND() *(SELECT MAX(id) FROM keyword)
) AS id) AS r2 ON r1.id >= r2.id 
WHERE Updet='published' 
ORDER BY r1.id ASC LIMIT 1

不工作，请帮忙..
