I have a table as follows
table_user
id name status flag country
====================================================================================================
1 AB 1 0 US
2 BC 1 0 UK
3 CD 0 0 IN
4 DE 3 0 BR
5 EF 3 0 UK
6 FG 2 0 IN
7 GH 4 0 IN
I want to count the no. of records where
status
= 1 as totalactiverecords
,
status
= 0 as totalinactiverecords
,
status
= 3 as totalrecentactiverecords
,
status
= 2 as totalemailnotverifiedrecords
,
status
= 4 as totalemailverifiedrecords
,
, and country
is UK
, all in a single SELECT statement .
Is there any specific way to do it?
I have thought of something like
SELECT COUNT(*) as totalactiverecords WHERE status=1
COUNT(*) as totalinactiverecordsWHERE status=0,
COUNT(*) as totalemailnotverifiedrecords WHERE status=2,
COUNT(*) as totalrecentactiverecords WHERE status=3,
COUNT(*) as totalemailverifiedrecords WHERE status=4
FROM table_user where country=IN
,but that does not seem to work.
You can try this query:
SELECT count(case status when '1' then 1 else null end) as totalactiverecords,
count(case status when '0' then 1 else null end) as totalinactiverecords,
count(case status when '2' then 1 else null end) as totalemailnotverifiedrecords,
count(case status when '3' then 1 else null end) as totalrecentactiverecords,
count(case status when '4' then 1 else null end) as totalemailverifiedrecords
FROM table_user where country='IN'
I usually use CASE WHEN
in this kind of problem:
SELECT sum(case when status = 1 then 1 end) as totalactiverecords,
COUNT sum(case when status = 0 then 1 end) as totalinactiverecords,
COUNT sum(case when status = 2 then 1 end) as totalemailnotverifiedrecord,
COUNT sum(case when status = 3 then 1 end) as totalrecentactiverecords,
COUNT sum(case when status = 4 then 1 end) as totalemailverifiedrecords
FROM table_user where country=IN
