Counts on single column for different conditions - php

Question

I require 3 different counts on single column for different conditions.
Table structure:
interview-
id-int(10)
c_id-int(10)
experience-varchar2(100)
experience have 3 different values-
1)positive
2)negative
3)neutral
I require 3 different counts of "count_positive", "count_negative" and "count_neutral" for where condition of c_id=10.
I know it can get by 3 different queries. Can I able to get 3 counts by single query?

Answer 1

SELECT
SUM(CASE experience
WHEN 'positive' THEN 1
ELSE 0
END) AS CountPositive
, SUM(CASE experience
WHEN 'negative' THEN 1
ELSE 0
END) AS CountNegative
, SUM(CASE experience
WHEN 'neutral' THEN 1
ELSE 0
END) AS CountNeutral
FROM Interview
WHERE c_id = 10

Answer 2

select 'Positive Count' , count(*)
from interview
where experience = 'positive'
UNION
select 'Negative Count' , count(*)
from interview
where experience = 'negative'
UNION
select 'Neutral' , count(*)
from interview
where experience = 'neutral'

Answer 3

This is the modified version of Adam Wenger answer:
SELECT
COUNT(CASE experience
WHEN 'positive' THEN 1
ELSE NULL
END) AS CountPositive
, COUNT(CASE experience
WHEN 'negative' THEN 1
ELSE NULL
END) AS CountNegative
, COUNT(CASE experience
WHEN 'neutral' THEN 1
ELSE NULL
END) AS CountNeutral
FROM Interview
WHERE c_id = 10

Answer 4

I think this works fine:
select 'count of ' + experience,
count(experience)
from interview
where c_id=10
group by experience

Answer 5

I got solution for active record query in Codeigniter:
$this->db->select('SUM(CASE experience
WHEN "positive" THEN 1
ELSE 0
END) AS CountPositive
, SUM(CASE experience
WHEN "negative" THEN 1
ELSE 0
END) AS CountNegative
, SUM(CASE experience
WHEN "neutral" THEN 1
ELSE 0
END) AS CountNeutral');
$this->db->where('c_id',10);
$query=$this->db->get('interview');
$result=$query->result();
$interview_experience=$result[0];
$positive_count=$interview_experience->CountPositive;
$negative_count=$interview_experience->CountNegative;
$neutral_count=$interview_experience->CountNeutral;
