如何将5组数据从一列变成5个不同的列

Question

我现在的table是这样的

CPNT_ID	Org_Id	Stud ID	Compl_Dte
Trainee	Org001	101010	Nov 13, 2016
SvcTech	Org001	101010	Nov 13, 2016
CrewChief	Org001	101010	Nov 13, 2016
Trainee	Org001	101013	Nov 13, 2016
SvcTech	Org001	101013	Nov 13, 2016
Trainee	Org002	101011	Nov 13, 2016
SvcTech	Org002	101011	Nov 13, 2016
Trainee	Org002	101012	Nov 13, 2016

如果我正在查看一个组织，这会起作用，但如果我需要查看多个组织，我需要 table 看起来像这样。我没有足够的声誉来聊天

Organization	Trainee	SvcTech	CrewChief	SvcCoord	Appr
Org001	2	2	1	0	0
Org002	2	1	0	0	0

这是我的代码

select 
cpnt.cpnt_id,
s.ORG_ID,
pc.stud_id,
pc.compl_dte
from 
        pa_stud_program sp,
        pa_program p,
        pa_student s,
        pa_stud_cpnt pc,
        ps_program_type pt,
        pa_cpnt cpnt
WHERE p.PROGRAM_SYS_GUID = sp.PROGRAM_SYS_GUID
    and pc.compl_dte is not null
    and cpnt.cpnt_id in ('Trainee','SvcTech','CrewChief','SvcCoord','Appr')
    and s.jp_id in ('1801','1805','1810','1811')
    and s.EMP_STAT_ID = 'Active'
    AND cpnt.CPNT_TYP_ID     = p.CPNT_TYP_ID
    AND cpnt.CPNT_ID         = p.CPNT_ID
    AND cpnt.REV_DTE         = p.REV_DTE
    AND pc.STUD_ID           = sp.STUD_ID
    AND sp.stud_id           = s.STUD_ID
    AND pc.CPNT_ID           = sp.CPNT_ID
    AND pc.CPNT_TYP_ID       = sp.CPNT_TYP_ID
    AND pc.REV_DTE           = sp.REV_DTE
    AND pc.seq_num           = sp.seq_num
    AND pt.PROGRAM_TYPE_ID   = p.PROGRAM_TYPE   
    /** and s.PERSON_ID_EXTERNAL  in [UserSearch]*/

您可以使用 case when 旋转 table，并在外层分组。 SQL 代码如下：

select ORG_ID as Organization
,sum(case when cpnt_id = 'Trainee' then 1 else 0 end) as Trainee
,sum(case when cpnt_id = 'SvcTech' then 1 else 0 end) as SvcTech
,sum(case when cpnt_id = 'CrewChief' then 1 else 0 end) as CrewChief
,sum(case when cpnt_id = 'SvcCoord' then 1 else 0 end) as SvcCoord
,sum(case when cpnt_id = 'Appr' then 1 else 0 end) as Appr
        
from (
select 
cpnt.cpnt_id,
s.ORG_ID,
pc.stud_id,
pc.compl_dte
from 
        pa_stud_program sp,
        pa_program p,
        pa_student s,
        pa_stud_cpnt pc,
        ps_program_type pt,
        pa_cpnt cpnt
WHERE p.PROGRAM_SYS_GUID = sp.PROGRAM_SYS_GUID
    and pc.compl_dte is not null
    and cpnt.cpnt_id in ('Trainee','SvcTech','CrewChief','SvcCoord','Appr')
    and s.jp_id in ('1801','1805','1810','1811')
    and s.EMP_STAT_ID = 'Active'
    AND cpnt.CPNT_TYP_ID     = p.CPNT_TYP_ID
    AND cpnt.CPNT_ID         = p.CPNT_ID
    AND cpnt.REV_DTE         = p.REV_DTE
    AND pc.STUD_ID           = sp.STUD_ID
    AND sp.stud_id           = s.STUD_ID
    AND pc.CPNT_ID           = sp.CPNT_ID
    AND pc.CPNT_TYP_ID       = sp.CPNT_TYP_ID
    AND pc.REV_DTE           = sp.REV_DTE
    AND pc.seq_num           = sp.seq_num
    AND pt.PROGRAM_TYPE_ID   = p.PROGRAM_TYPE   
) as a

group by ORG_ID
