[英]How to join result of two sql statements into one table and different columns
我有三个选择查询,它们根据不同的where子句从同一张表中返回总记录,成功记录和失败记录。 我想将所有这些语句的结果合并到一个表中以创建存储过程,但结果表应具有cdr,success,failure的三个不同列
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' )
联合会在一列中给出结果,因此它无效。 任何其他想法
只需将每个选择语句括在括号中,为每个选择语句指定别名,然后在顶部使用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。
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
from abc
