如何将两个sql语句的结果连接到一个表和不同的列中

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在一列中给出结果,因此不起作用.任何其他想法

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SELECT在顶部使用:

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.
