MySQL COUNT，GROUP_CONCAT和GROUP BY一起

Question

I have a MySQL table like following.

IP Host Label BotName
1  A    good    aa
1  A    good    aa
2  C    good    bb
3  C    bad     cc
4  D    bad     dd
4  D    bad     ee
5  E    good    ff
5  E    good    gg

I want to get the output like following.

count Host BotName  Type
2     A    aa       good
1     C    bb       good
1     C    cc       bad
2     D    dd,ee    bad
2     E    ff,gg    good

Conditions are:

1. Count IPs groupby Host and Label
2. If the botnames are different concatenate them using commas.

Following is which I have tried, but couldn't get expected results.

$result2 = mysql_query("SELECT GROUP_CONCAT(BotName) name FROM (SELECT *, COUNT(IP) FROM mytable GROUP BY Host,Label)q");

Answer 1

Try this

SELECT COUNT(*) AS `count`,
       HOST,
       GROUP_CONCAT(distinct boatname) BotName,
       label as Type
FROM temp
GROUP BY host,label

Answer 2

Count and GROUP_CONCAT will get the values, but you need to group by the Host and label / type fields.

SELECT  COUNT(*) AS `count`, Host, GROUP_CONCAT(DISTINCT Botname) AS Botname, label AS type
FROM name
GROUP BY Host, type
