我有一个mysql表,如下所示:当访问者访问网站时,它将访问者id和页面id存储为一行。SELECT COUNT(visid),visid FROM vislog GROUP BY visid ORDER BY COUNT(visid) DESC
但我不知道下一步该怎么计算可以像MySQL查询一样做吗?

我的计数应该是5,5,5,2,1 (因为在0-5范围内有5个数字,1-6中有5个数字,2-7中有2个数字,4-9中有1个数
这是我的问题 WHERE (date >= '2012-06-26'AND date < '2012-06-30') AND (Avail > '0')SELECT COUNT(*) as total, toys, date FROM T2
WHERE (date >= '2012-06-26'AND>= '2012-06-26
