Question

i have a table named temp. columns are id, telco, shortcode,hotkey.

id  telco  shortcode hotkey
1    asdf    123      ib
2    gra     123      sb
3    cc      123      sb
4    bl      123      ibb

using mysql query i want output count(shortcode) group by telco where hotkey ib shortcode 123 and
count(shortcode) group by telco where hotkey sb shortcode 123

telco   ib         sb 
asdf     1         0
gra      0         1
cc       0         1
bl       1         0 

if i use the following query

SELECT COUNT(`shortcode`) WHERE `hotkey` = 'ib' AND `shortcode` = 123
SELECT COUNT(`shortcode`) WHERE `hotkey` = 'sb' AND `shortcode` = 123   

then i get out in the following way

telco   ib          

asdf     1         
gra      0         
cc       0         
bl       1     

telco   sb

asdf     1         
gra      0         
cc       0         
bl       1  

but i don’t want this

Answer 1

you want to use sum case like

 Select
      Telco,
       Sum  (   Case when hotkey = 'ib' then 1 else 0 end) as ib,
       Sum  (   Case when hotkey = 'sb' then 1 else 0 end) as sb
From 
      Yourtable 
 Group By
   Telco

Note current versions of Oracle an Sql server have the option to use the pivot syntax
