Question

我是Oracle的新手;我写了两个存储过程，它们有两个不同的参数。我想将这两个存储过程中的查询合并到单个存储过程中的单个查询中，并确保它支持任何条件。

这些是存储过程：

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;

我的目标是将这两个单独过程中的查询组合成一个查询，这样如果我组合所有参数，我有in_emp_no，in_vendor_id，in_vendor_startdate，in_vendor_enddate除了公共参数之外，任何参数都可以为null我想确保这些东西不会影响查询的其余部分，即使它不是null 对于ex，我只有in_emp_no =＆＃39; xxxx＆＃39;和常见的输入其余的参数类似 in_vendor_id等为null。我想让我的查询工作，即使使用单参数来过滤结果集注意不使用动态SQL 谢谢 BJ

您可以使查询中的列表现为可选，就您的加入而言，您可能需要使用各种组合来确保一切正常。

样本表

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;

Sample 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;

示例通话

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;
