Question

我有三个选择查询，它们根据不同的where子句从同一个表中返回总记录，成功记录和失败记录。我想将所有这些语句的结果加入到一个表中以便创建我的存储过程但是结果表应该有三个不同的列用于cdr，成功，失败

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' )

Union会在一列中显示结果，因此无效。任何其他想法

Answer 1

只需将每个select语句包装在括号中，为每个select语句指定一个别名，并在顶部使用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，您将每个查询视为单个列。

Answer 2

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 3

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

Answer 4

  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
