How not to count a value in each case, how to count it once and use in each case?
How about you move the count to a subquery and move the case outside like this:
select `short_date`, `group`, `subgroup`, `row`,
CASE
WHEN nb_guild >= 1 AND nb_guild <= 5 THEN '1 - 5 '
WHEN nb_guild >= 6 AND nb_guild <= 10 THEN '6 - 10 '
WHEN nb_guild >= 11 AND nb_guild <= 15 THEN '11 - 15 '
WHEN nb_guild >= 16 AND nb_guild <= 20 THEN '16 - 20 '
WHEN nb_guild >= 21 AND nb_guild <= 25 THEN '21 - 25 '
WHEN nb_guild >= 30 THEN '> 30'
END AS `value`
from
(
SELECT '2017-05-30' AS `short_date`,
'Stats' AS `group`,
'Active ' AS `subgroup`,
'' AS `row`,
COUNT(DISTINCT(guild_name)) as nb_guild
FROM table
WHERE guild_name !=0
GROUP BY
`short_date`,
`group`,
`subgroup`
) as subquery
This way your count only gets executed once in the subquery and your outer query does its treatment on the resulting resultset.

The data is stored in DB in UTC , I have to convert local to UTC fetch it then show result in local time .
Now I am from India so if I want to search the data for today I have to query from 22nd March 6:30 PM UTC to 23rd March 6:30 PM UTC . Now Say I want to check data for every day of week until now which is 4:30 PM local . Now I wrote this query [ In simple words my objective is to get visitor number of each day from 12 AM to 4:30 PM ]
SELECT
FLOOR(TIMESTAMPDIFF(HOUR, "2017-03-16 18:29:59",
visit.date_created)/24) as dayofweek,
DAYOFWEEK(visit.date_created) day_num,
#rownum := #rownum + 1 as date_created_set_av,
count(distinct(visit.pkey)) AS Visits,
sum(revenue) AS Revenue,
sum(revenue) / count(distinct(visit.pkey)) as EPC
FROM la_20.visit, la_20.action
cross join (select #rownum := 0) r
WHERE visit.pkey=action.pkey and (visit.is_bot = 0)
AND visit.date_created >="2017-03-16 18:29:59"
AND visit.date_created <="2017-03-23 18:29:59"
AND TIME(visit.date_created)<="16:30:00"
GROUP BY dayofweek order by day_num
but what it does is fetch the value from 2017-03-23 00:00:00 to 2017-03-23 16:30:00 . What I need is to show result of 16th to 23rd everyday's data from 18:29:59 to 16:30:00. Remember I need the result of everyday's not one day's. Can anyone help
You should change your WHERE clause into
WHERE visit.pkey=action.pkey and (visit.is_bot = 0)
AND visit.date_created >="2017-03-22 18:29:59" and visit.date_created <="2017-03-23 14:29:59"
UPDATED
Today midnight: DATEADD(d,0,DATEDIFF(d,0,GETDATE()))
Today 4pm: DATEADD(HOUR, 16, DATEADD(d,0,DATEDIFF(d,0,GETDATE())))
WHERE visit.pkey=action.pkey and (visit.is_bot = 0)
AND visit.date_created >= DATEADD(d,0,DATEDIFF(d,0,GETDATE())) and visit.date_created <= DATEADD(HOUR, 16, DATEADD(d,0,DATEDIFF(d,0,GETDATE())))
Update 2:
Then you'll have to expand your where clause like this I guess.
WHERE visit.pkey=action.pkey and (visit.is_bot = 0)
AND (
(visit.date_created >= DATEADD(d, 0,DATEDIFF(d,0,GETDATE())) and visit.date_created <= DATEADD(HOUR, 16, DATEADD(d, 0,DATEDIFF(d,0,GETDATE()))))
OR (visit.date_created >= DATEADD(d,-1,DATEDIFF(d,0,GETDATE())) and visit.date_created <= DATEADD(HOUR, 16, DATEADD(d,-1,DATEDIFF(d,0,GETDATE()))))
OR (visit.date_created >= DATEADD(d,-2,DATEDIFF(d,0,GETDATE())) and visit.date_created <= DATEADD(HOUR, 16, DATEADD(d,-2,DATEDIFF(d,0,GETDATE()))))
OR (visit.date_created >= DATEADD(d,-3,DATEDIFF(d,0,GETDATE())) and visit.date_created <= DATEADD(HOUR, 16, DATEADD(d,-3,DATEDIFF(d,0,GETDATE()))))
OR (visit.date_created >= DATEADD(d,-4,DATEDIFF(d,0,GETDATE())) and visit.date_created <= DATEADD(HOUR, 16, DATEADD(d,-4,DATEDIFF(d,0,GETDATE()))))
OR (visit.date_created >= DATEADD(d,-5,DATEDIFF(d,0,GETDATE())) and visit.date_created <= DATEADD(HOUR, 16, DATEADD(d,-5,DATEDIFF(d,0,GETDATE()))))
OR (visit.date_created >= DATEADD(d,-6,DATEDIFF(d,0,GETDATE())) and visit.date_created <= DATEADD(HOUR, 16, DATEADD(d,-6,DATEDIFF(d,0,GETDATE()))))
)
Have you tried the following where clause instead?
WHERE visit.pkey=action.pkey and (visit.is_bot = 0)
AND visit.date_created >="2017-03-22 18:29:59"
AND visit.date_created <="2017-03-23 14:29:59"
3. Edit
OK, since OP wants something different again - and why not ;-) - here is another solution that might (or might not) solve his problem:
SELECT
COUNT( CASE WHEN d between
adddate(curdate(), interval -7 day) AND addtime(adddate(curdate(), interval -7 day),'16:00:00')
THEN 1 END ) dm7,
COUNT( CASE WHEN d between
adddate(curdate(), interval -6 day) AND addtime(adddate(curdate(), interval -6 day),'16:00:00')
THEN 1 END ) dm6,
COUNT( CASE WHEN d between
adddate(curdate(), interval -5 day) AND addtime(adddate(curdate(), interval -5 day),'16:00:00')
THEN 1 END ) dm5,
COUNT( CASE WHEN d between
adddate(curdate(), interval -4 day) AND addtime(adddate(curdate(), interval -4 day),'16:00:00')
THEN 1 END ) dm4,
COUNT( CASE WHEN d between
adddate(curdate(), interval -3 day) AND addtime(adddate(curdate(), interval -3 day),'16:00:00')
THEN 1 END ) dm3,
COUNT( CASE WHEN d between
adddate(curdate(), interval -2 day) AND addtime(adddate(curdate(), interval -2 day),'16:00:00')
THEN 1 END ) dm2,
COUNT( CASE WHEN d between
adddate(curdate(), interval -1 day) AND addtime(adddate(curdate(), interval -1 day),'16:00:00')
THEN 1 END ) dm1,
COUNT( CASE WHEN d between
curdate() AND addtime( curdate() ,'16:00:00')
THEN 1 END ) today
FROM (select '2017-03-17 15:00:01' d
union all select '2017-03-19 14:00:01'
union all select '2017-03-19 12:00:01'
union all select '2017-03-19 13:00:01'
union all select '2017-03-19 11:00:01'
union all select '2017-03-20 11:20:01'
union all select '2017-03-20 11:30:01'
union all select '2017-03-20 10:40:01'
union all select '2017-03-20 10:23:01' ) dates
This is an isolated query that works directly on the sample data given in the subquery. It results in the following list ("dm1"=day minus 1):
dm7 | dm6 | dm5 | dm4 | dm3 | dm2 | dm1 | today
1 | 0 | 4 | 4 | 0 | 0 | 0 | 0

How do I add in a "range of years" to my Case Statement below? I just need to fix the "INTERVAL 6 YEAR" & "INTERVAL 5 YEAR" criteria.
Here is the criteria I need to model:
If 1~5 years, then 11
If 6~10 years, then 14
If 11+ years, then 18
CASE WHEN hiredate < DATE_SUB(NOW(),INTERVAL 11 YEAR)
THEN '18'
WHEN hiredate < DATE_SUB(NOW(),INTERVAL 6 YEAR)
THEN '14'
WHEN hiredate < DATE_SUB(NOW(),INTERVAL 5 YEAR)
THEN '11'
ELSE '0' END AS Non_Management_Accrual
You can use DATEDIFF method to calculate number of days between two days and divide it by 365 to get years. Based on these, you can write up the case statement, e.g.:
SELECT id, CASE WHEN FLOOR(DATEDIFF(NOW(), hiredate) / 365) < 1
THEN '0'
WHEN FLOOR(DATEDIFF(NOW(), hiredate) / 365) < 6
THEN '11'
WHEN FLOOR(DATEDIFF(NOW(), hiredate) / 365) < 11
THEN '14'
ELSE '18'
END AS Non_Management_Accrual
FROM emp;
Here is the SQL Fiddle.
Darshan, I ended up creating Views on the MySQL side then adding the view into FROM statement of your code above. This gave me the correct output. Thanks.

I have created a SELECT statement where I fetch the time difference from now to a certain date in my database.
SELECT
`username`,
TIMESTAMPDIFF(HOUR, `a_date`, NOW()) AS `timediff`
FROM
`User`
... results in something like
username | timediff
-------------------
john | 441
henry | 1624
mike | 4
kyle | NULL
Now I would like to group them into pre defined groups, e.g.
NULL
less than 20
greater than 20
How can I JOIN the above result with a static set of predefined values and how can I use those values as my grouping identifier?
group | amount
--------------
NULL | 1
lt 20 | 1
gt 20 | 2
You can use case statement with group by:
SELECT (CASE WHEN TIMESTAMPDIFF(HOUR, `a_date`, NOW()) < 20 THEN 'lt 20'
WHEN TIMESTAMPDIFF(HOUR, `a_date`, NOW()) >= 20 THEN 'gt 20'
END) as grp, COUNT(*)
FROM `User`
GROUP BY grp;
As a side note: I usually repeat the case statement in the group by, because many databases don't allow column aliases there:
SELECT (CASE WHEN TIMESTAMPDIFF(HOUR, `a_date`, NOW()) < 20 THEN 'lt 20'
WHEN TIMESTAMPDIFF(HOUR, `a_date`, NOW()) >= 20 THEN 'gt 20'
END) as grp, COUNT(*)
FROM `User`
GROUP BY (CASE WHEN TIMESTAMPDIFF(HOUR, `a_date`, NOW()) < 20 THEN 'lt 20'
WHEN TIMESTAMPDIFF(HOUR, `a_date`, NOW()) >= 20 THEN 'gt 20'
END);
I have a table in which the value are
Table_hello
date col2
2012-01-31 23:01:01 a
2012-06-2 12:01:01 b
2012-06-3 20:01:01 c
Now i want to select date
in days if it is 3 days before or less
in hours if it is 24 hours before or less
in minutes if it is 60 minutes before or less
in seconds if it is 60 seconds before or less
in simple format if it is before 3days or more
OUTPUT
for row1 2012-01-31 23:01:01
for row2 1 day ago
for row3 1 hour ago
UPDATE
My sql query
select case
when TIMESTAMPDIFF(SECOND, `date`,current_timestamp) <= 60
then concat(TIMESTAMPDIFF(SECOND, `date`,current_timestamp), ' seconds')
when TIMESTAMPDIFF(DAY, `date`,current_timestamp) <= 3
then concat(TIMESTAMPDIFF(DAY, `date`,current_timestamp), ' days')end
when TIMESTAMPDIFF(HOUR, `date`,current_timestamp) <= 60
then concat(TIMESTAMPDIFF(HOUR, `date`,current_timestamp), ' hours')
when TIMESTAMPDIFF(MINUTE, `date`,current_timestamp) <= 60
then concat(TIMESTAMPDIFF(MINUTE, `date`,current_timestamp), ' minutes')
from table_hello
Only problem is i am unable to use break and default in sql like switch case in c++
Use the timestampdiff function for that and CASE:
select case
when TIMESTAMPDIFF(SECOND, `date`,current_timestamp) <= 60
then concat(TIMESTAMPDIFF(SECOND, `date`,current_timestamp), ' seconds')
when TIMESTAMPDIFF(DAY, `date`,current_timestamp) <= 3
and TIMESTAMPDIFF(DAY, `date`,current_timestamp) >= 1
...
end as time_diff
from Table_hello
where TIMESTAMPDIFF(DAY, `time`,current_timestamp) >= 3
