SQL三个查询合并为三列

Question

我有三个查询，我想合并为三列。

我要寻找这样的输出：

DEPTNAME1 -----计数（不同pat_id Q1）-----计数（不同pat_id Q2）-----计数（不同pat_id Q1）/计数（不同pat_id Q2）

DEPTNAME2 -----计数（不同pat_id Q1）-----计数（不同pat_id Q2） - - - - 计数（不同的pat_id Q1）/计数（不同pat_id Q2）

ETC

我给Q1当前的代码：

select DEP.DEPARTMENT_NAME, 
count(distinct hsp.pat_id) 
from pat_enc_hsp hsp 
left outer join clarity_adt adt 
on hsp.pat_enc_csn_id = adt.pat_enc_csn_id 
left outer join clarity_dep dep 
on ADT.DEPARTMENT_ID = dep.DEPARTMENT_ID 
inner join patient pat 
on hsp.PAT_ID = pat.PAT_ID 
left outer join ip_flwsht_rec rec 
on rec.INPATIENT_DATA_ID = hsp.INPATIENT_DATA_ID 
left outer join ip_flwsht_meas meas 
on rec.FSD_ID = meas.FSD_ID 
left outer join ip_flo_gp_data 
on meas.FLO_MEAS_ID = ip_flo_gp_data.FLO_MEAS_ID 
where adt.department_id IN (1,2,3,4,5) 
and (hsp.ed_disposition_c is null or hsp.ed_disposition_c not in ('5','6')) 
and hsp.HOSP_ADMSN_TIME between TO_DATE ('08-10-2014 00:00:00', 'DD-MM-YYYY HH24:MI:SS') and TO_DATE ('08-10-2014 23:59:59', 'DD-MM-YYYY HH24:MI:SS') 
GROUP BY DEP.DEPARTMENT_NAME 

我给Q2当前的代码：

select DEP.DEPARTMENT_NAME, 
count(distinct hsp.pat_id) 
from pat_enc_hsp hsp 
left outer join clarity_adt adt 
on hsp.pat_enc_csn_id = adt.pat_enc_csn_id 
left outer join clarity_dep dep 
on ADT.DEPARTMENT_ID = dep.DEPARTMENT_ID 
inner join patient pat 
on hsp.PAT_ID = pat.PAT_ID 
left outer join ip_flwsht_rec rec 
on rec.INPATIENT_DATA_ID = hsp.INPATIENT_DATA_ID 
left outer join ip_flwsht_meas meas 
on rec.FSD_ID = meas.FSD_ID 
left outer join ip_flo_gp_data 
on meas.FLO_MEAS_ID = ip_flo_gp_data.FLO_MEAS_ID 
where adt.department_id IN (1,2,3,4,5) 
and (hsp.ed_disposition_c is null or hsp.ed_disposition_c not in ('5','6')) 
and hsp.HOSP_ADMSN_TIME between TO_DATE ('08-10-2014 00:00:00', 'DD-MM-YYYY HH24:MI:SS') and TO_DATE ('08-10-2014 23:59:59', 'DD-MM-YYYY HH24:MI:SS') 
and meas.flo_meas_id in ('00', 
'7', 
'8', 
'9', 
'0') 
GROUP BY DEP.DEPARTMENT_NAME 

Q3是从特定的行Q1 /输出输出特定的行Q2：

谢谢所有帮助

Answer 1

select DEPARTMENT_NAME, q1, q2, decode(q2, 0, null, q1/q2) from 
(select DEP.DEPARTMENT_NAME, 
count(distinct hsp.pat_id) q1, 
count(distinct case when meas.flo_meas_id in ('00', '7', '8', '9', '0') then hsp.pat_id else NULL end) q2 
from pat_enc_hsp hsp 
left outer join clarity_adt adt on hsp.pat_enc_csn_id = adt.pat_enc_csn_id 
left outer join clarity_dep dep on ADT.DEPARTMENT_ID = dep.DEPARTMENT_ID 
inner join patient pat on hsp.PAT_ID = pat.PAT_ID 
left outer join ip_flwsht_rec rec on rec.INPATIENT_DATA_ID = hsp.INPATIENT_DATA_ID 
left outer join ip_flwsht_meas meas on rec.FSD_ID = meas.FSD_ID 
left outer join ip_flo_gp_data on meas.FLO_MEAS_ID = ip_flo_gp_data.FLO_MEAS_ID 
where adt.department_id IN (1,2,3,4,5) 
and (hsp.ed_disposition_c is null or hsp.ed_disposition_c not in ('5','6')) 
and hsp.HOSP_ADMSN_TIME between TO_DATE ('08-10-2014 00:00:00', 'DD-MM-YYYY HH24:MI:SS') and TO_DATE ('08-10-2014 23:59:59', 'DD-MM-YYYY HH24:MI:SS') 
GROUP BY DEP.DEPARTMENT_NAME);
