두 개의 select 문을 하나에 합치기

Question

결과를 함께 반환하려면이 명령문을 어떻게 참여 시키나요?

쿼리 1 :

select scheduleentry.scheduledate, 
    patientdemographics.accountnumber, 
    patientdemographics.firstname, 
    patientdemographics.middleinitial, 
    patientdemographics.lastname, 
    patientdemographics.address1, 
    patientdemographics.address2, 
    patientdemographics.city, 
    patientdemographics.state, 
    patientdemographics.zipcode, 
    patientdemographics.dateofbirth, 
    patientdemographics.sex, 
    patientdemographics.hometelephone, 
    patientinsuranceprofiles.insurance1name, 
    patientinsuranceprofiles.insurance1policynumber, 
    patientinsuranceprofiles.insurance1policygroupnumber, 
    patientinsuranceprofiles.insurance1guarantorfirstname as insuredfirstname, 
    patientinsuranceprofiles.insurance1guarantormiddleinitial as insuredmiddleinitial, 
    patientinsuranceprofiles.insurance1guarantorlastname as insuredlastname, 
    patientinsuranceprofiles.insurance1guarantoraddress1 as insuredaddress1, 
    patientinsuranceprofiles.insurance1guarantoraddress2 as insuredaddress2, 
    patientinsuranceprofiles.insurance1guarantorcity as insuredcity, 
    patientinsuranceprofiles.insurance1guarantorstate as insuredstate, 
    patientinsuranceprofiles.insurance1guarantorzipcode as insuredzip, 
    patientinsuranceprofiles.insurance1guarantordateofbirth as insureddob, 
    patientinsuranceprofiles.insurance1guarantorsex as insuredsex, 
    patientinsuranceprofiles.insurance1guarantortelephonenumber as insuredhomenumber, 
    insurances.eligibilitypayornumber 
from patientdemographics 
inner join patientinsuranceprofiles 
on patientdemographics.accountnumber = patientinsuranceprofiles.patientaccountnumber 
inner join scheduleentry 
on patientinsuranceprofiles.patientaccountnumber = scheduleentry.patientaccount 
inner join insurances 
on patientinsuranceprofiles.insurance1mnemonic = insurances.mnemonic 
where datediff(d, getdate(), scheduledate) = 1 
    and patientinsuranceprofiles.activeflag = 1 
order by scheduledate asc 

질의 2 : 예를 들어, 두 개의 쿼리 사이에 UNION ALL를 사용할 수

select scheduleentry.scheduledate, 
    patientdemographics.accountnumber, 
    patientdemographics.firstname, 
    patientdemographics.middleinitial, 
    patientdemographics.lastname, 
    patientdemographics.address1, 
    patientdemographics.address2, 
    patientdemographics.city, 
    patientdemographics.state, 
    patientdemographics.zipcode, 
    patientdemographics.dateofbirth, 
    patientdemographics.sex, 
    patientdemographics.hometelephone, 
    patientinsuranceprofiles.insurance2name, 
    patientinsuranceprofiles.insurance2policynumber, 
    patientinsuranceprofiles.insurance2policygroupnumber, 
    patientinsuranceprofiles.insurance2guarantorfirstname as insuredfirstname, 
    patientinsuranceprofiles.insurance2guarantormiddleinitial as insuredmiddleinitial, 
    patientinsuranceprofiles.insurance2guarantorlastname as insuredlastname, 
    patientinsuranceprofiles.insurance2guarantoraddress1 as insuredaddress1, 
    patientinsuranceprofiles.insurance2guarantoraddress2 as insuredaddress2, 
    patientinsuranceprofiles.insurance2guarantorcity as insuredcity, 
    patientinsuranceprofiles.insurance2guarantorstate as insuredstate, 
    patientinsuranceprofiles.insurance2guarantorzipcode as insuredzip, 
    patientinsuranceprofiles.insurance2guarantordateofbirth as insureddob, 
    patientinsuranceprofiles.insurance2guarantorsex as insuredsex, 
    patientinsuranceprofiles.insurance2guarantortelephonenumber as insuredhomenumber, 
    insurances.eligibilitypayornumber 
from patientdemographics 
inner join patientinsuranceprofiles 
on patientdemographics.accountnumber = patientinsuranceprofiles.patientaccountnumber 
inner join scheduleentry 
on patientinsuranceprofiles.patientaccountnumber = scheduleentry.patientaccount 
inner join insurances 
on patientinsuranceprofiles.insurance2mnemonic = insurances.mnemonic 
where datediff(d, getdate(), scheduledate) = 1 
    and patientinsuranceprofiles.activeflag = 1 
order by scheduledate asc 

Answer 1

하나의 방법은 제안 된 다른 방법처럼 UNION ALL 방식을 사용하는 것입니다.

(Query 1) 
union all
