如何將兩個sql語句的結果聯接到一個表和不同的列中

Question

我有三個選擇查詢，它們根據不同的where子句從同一張表中返回總記錄，成功記錄和失敗記錄。 我想將所有這些語句的結果合並到一個表中以創建存儲過程，但結果表應具有cdr，success，failure的三個不同列

SELECT Count(*) AS cdr 
FROM   ABC AS c WITH (NOLOCK) 
WHERE  APPID IN( 1, 2 ) 
       AND CALLDATE = '2012-10-09' 

SELECT Count(*) AS success 
FROM   ABC AS d WITH (NOLOCK) 
WHERE  APPID IN( 44, 45 ) 
       AND CALLDATE = '2012-10-09' 
       AND HANGUPCODE IN ( 'man', 'mach' ) 

SELECT Count(*) AS fail 
FROM   ABC WITH (NOLOCK) 
WHERE  APPID IN( 44, 45 ) 
       AND CALLDATE = '2012-10-09' 
       AND HANGUPCODE NOT IN ( 'man', 'mach' ) 

聯合會在一列中給出結果，因此它無效。 任何其他想法

Answer 1

只需將每個選擇語句括在括號中，為每個選擇語句指定別名，然后在頂部使用SELECT ：

SELECT 
  (select count(*) as cdr  
   from abc as c with (nolock) 
   where appid in(1,2)  and calldate = '2012-10-09'
  ) AS Column1,  
  (select count(*) as success  
   from abc as d with (nolock) 
   where appid in(44,45) and calldate = '2012-10-09' 
       and hangupcode in ('man', 'mach')
  ) AS Column2, 
  (select count(*) as fail  
   from abc  with (nolock) 
   where appid in(44,45) and calldate = '2012-10-09' 
       and hangupcode not in  ('man', 'mach')
  ) AS Column3

基本上，您將每個查詢視為一個單獨的列。

Answer 2

  SELECT a.cdr, b.success, c.failure FROM 
  (SELECT count(*) AS cdr  
   FROM abc as c WITH (NOLOCK) 
   WHERE appid IN (1,2) AND
         calldate = '2012-10-09'
  ) AS a,   
  (SELECT count(*) AS success  
   FROM abc AS d WITH (NOLOCK) 
   WHERE appid IN (44,45) AND 
         calldate = '2012-10-09' AND 
         hangupcode IN ('man', 'mach')
  ) AS b,  
  (SELECT count(*) AS fail  
   FROM abc WITH (NOLOCK) 
   WHERE appid IN (44,45) AND
         calldate = '2012-10-09' AND 
         hangupcode NOT IN ('man', 'mach')
  ) AS c

Answer 3

select a.cdr, b.success, c.fail from
( select count(*) as cdr  
from abc as c with (nolock) where appid in(1,2)  
and calldate = '2012-10-09' ) a
, ( select count(*) as success  
from abc as d with (nolock) where appid in(44,45)  
and calldate = '2012-10-09'
and hangupcode in ('man', 'mach') ) b
, ( select count(*) as fail  from abc  with (nolock) where appid in(44,45) and calldate = '2012-10-09'and hangupcode not in  ('man', 'mach') ) c

Answer 4

select
   sum(case when appid in(1,2) and calldate = '2012-10-09' then 1 else 0 end) as cdr,
   sum(case when appid in(44,45) and calldate = '2012-10-09'and hangupcode in ('man', 'mach') then 1 else 0 end) as success,
   sum(case when appid in(44,45) and calldate = '2012-10-09'and hangupcode not in  ('man', 'mach') then 1 else 0 end)as fail
from abc
