如何将两条sql语句的结果连接到一个表和不同的列中
我有三个select查询,它们根据不同的where子句从同一个表返回总记录、成功记录和失败记录。我想将所有这些语句的结果合并到一个表中,以便生成我的存储过程,但是生成的表应该有三个不同的列,分别是cdr、success和failure如何将两条sql语句的结果连接到一个表和不同的列中,sql,sql-server,stored-procedures,Sql,Sql Server,Stored Procedures,我有三个select查询,它们根据不同的where子句从同一个表返回总记录、成功记录和失败记录。我想将所有这些语句的结果合并到一个表中,以便生成我的存储过程,但是生成的表应该有三个不同的列,分别是cdr、success和failure SELECT Count(*) AS cdr FROM ABC AS c WITH (NOLOCK) WHERE APPID IN( 1, 2 ) AND CALLDATE = '2012-10-09' SELECT Count(*)
SELECT Count(*) AS cdr

SELECT Count(*) AS success

AND HANGUPCODE IN ( 'man', 'mach' )
SELECT Count(*) AS fail

AND HANGUPCODE NOT IN ( 'man', 'mach' )
Union在一列中给出结果,因此它将不起作用。任何其他想法只需将每个select语句用括号括起来,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,您将每个查询视为一个单独的列。我不明白,您想要一个只有一行和三列的结果集吗?
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
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
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
