计数行数多个查询

Question

我如何计算从以下查询返回的行数

SELECT * FROM ( SELECT * FROM data ORDER BY time) AS t1 GROUP BY fbid ORDER BY time

Answer 1

试试这个：

SELECT * 
FROM
 ( SELECT * FROM data ORDER BY time) AS t1
 GROUP BY fbid
 ORDER BY time
INNER JOIN
 SELECT COUNT(fbid) AS 'row count'
 FROM
 ( SELECT * FROM data ORDER BY time) AS t2
 GROUP BY fbid
 ORDER BY time
ON (t1.fbid=t2.fbid)
