いくつかの結合を使用して2つのストアドプロシージャを1つに結合する

Question

私はOracleにとって新しく、私は二つの異なるストアドプロシージャを書いています。その2つのストアドプロシージャ内のクエリを1つのストアドプロシージャ内の1つのクエリに結合し、それが任意の基準をサポートしていることを確認したいと思います。

これらは、ストアドプロシージャです：

procedure usp_testsp1(RC1 OUT RCT1,         
         in_dep_Id IN number, 
         in_Org_id IN number, 
         in_emp_no IN number) 
is 
begin 
     select emp.Name as name,select emp.phone as phone,select emp.Race as 
     race 
     from employee emp 
     JOIN 
     Project prj ON 
     emp.ProjectId=prj.ProjectId 
     JOIN Project_Org Prorg 
     ON prj.ProjectId=Prorg.ProjectId 
     JOIN Organization Org1 
     ON Prorg.OrgId=Org1.OrgId 
     JOIN Organization Org2 
     ON emp.OrgId=Org2.OrgId 
     AND Org2.OrgType=0 
WHERE (upper(emp.emp_No) in (in_emp_No)) 
AND Prorg.OrgId=in_Org_id    
AND Org2.OrgId=in_dep_Id        
end; 


procedure usp_testsp2(RC1 OUT RCT1, 
         in_dep_Id IN number, 
         in_Org_id IN number, 
         in_vendor_id IN raw, 
         in_vendor_startdate IN date, 
         in_vendor_enddate IN date) 
is 
begin 
OPEN RC1 FOR 
select emp.Name as name,select emp.phone as phone,select emp.Race as 
     race 
from 
    from employee emp 
     JOIN 
     Project prj ON 
     emp.ProjectId=prj.ProjectId 
     JOIN Project_Org Prorg 
     ON prj.ProjectId=Prorg.ProjectId 
     JOIN Organization Org1 
     ON Prorg.OrgId=Org1.OrgId 
     JOIN Organization Org2 
     ON emp.OrgId=Org2.OrgId 
     AND Org2.OrgType=0 
     INNER JOIN vendor_Emp 
     ON emp.employeeid=vendor_emp.employeeid 
     INNER JOIN Vendor 
     ON Vendor.VendorId=Vendor_emp.VendorId 
WHERE Prorg.OrgId=in_Org_id    
AND Org2.OrgId=in_dep_Id 
AND Vendor.VendorId=in_vendor_id   
AND vendor.StartDate=in_vendor_startdate AND Vendor.EndDate=in_vendor_enddate  
end; 

私の目標は、私はすべてのパラメータを組み合わせた場合、私はin_emp_no、in_vendor_id、in_vendor_startdateを持っているように、単一のクエリにこれら二つの別々のプロシージャ内のクエリを組み合わせることです、 in_vendor_enddateは、共通のパラメータとは別にパラメータがnullでもかまいません。ヌルではないにもかかわらず、これらのことが残りのクエリに影響しないようにしたいのです 私はin_emp_no = 'xxxx'と一般的な入力しかありません in_vendor_idなどの残りのパラメータはnullです。私は私のクエリは結果をフィルタリングするために1つでもPARAMTERで動作するようにしたいと思い は、クエリ内の列は、限り、あなたが行くのに参加するよう、オプションとして動作させることができ、動的SQLに おかげ BJ

を使用してNOTEWithout を設定し、さまざまな組み合わせでプレイして、すべてが機能することを確認する必要があるかもしれません。

サンプルテーブル

create table sqltest (
empid number, 
name varchar2(10), 
orgid number, 
depid number, 
vendorid number); 

insert into sqltest values(1,'BoB',1,1,21); 
insert into sqltest values(2,'Chuck',1,1,21); 
insert into sqltest values(3,'Mary',1,2,21); 
insert into sqltest values(4,'Jane',1,2,22); 
insert into sqltest values(5,'Rick',2,1,22); 
insert into sqltest values(6,'Samir',2,6,23); 
insert into sqltest values(7,'Kirk',3,6,23); 
insert into sqltest values(8,'Alex',3,9,23); 
commit; 

サンプルPROC

create or replace procedure calltest (
    rc1 out SYS_REFCURSOR, 
    pempid number, 
    porgid number, 
    pdepid number, 
    pvendorid number) 
is 
begin 
open rc1 for 
select * from sqltest 
where 
    (pempid IS NULL OR empid = pempid) and 
    (porgid IS NULL OR orgid = porgid) and 
    (pdepid IS NULL OR depid = pdepid) and 
    (pvendorid IS NULL OR vendorid = pvendorid); 

end; 

サンプル呼び出し

set autoprint on; 

var vcur refcursor; 
declare 
begin 
    calltest(rc1=>:vcur,pempid=>NULL,porgid=>1,pdepid=>NULL,pvendorid=>NULL); 
    --calltest(rc1=>:vcur,pempid=>NULL,porgid=>1,pdepid=>2,pvendorid=>NULL); 
    --calltest(rc1=>:vcur,pempid=>NULL,porgid=>1,pdepid=>2,pvendorid=>22); 
    --calltest(rc1=>:vcur,pempid=>NULL,porgid=>NULL,pdepid=>NULL,pvendorid=>23); 
end;
