How to accept multiple input parameters in comma separated in stored procedure

Albert ChaoOct 25 2021
create table staging
(key_id number(10),inv_id number(10), i_name varchar2(30), req_id number(10));


insert into staging values(110,1001,'test1',1);
insert into staging values(111,1002,'test2',2);

create table target_tab
(key_id number(10), inv_id number(10), i_name varchar2(30), req_id number(10));



Stored Procedure :

create or replace NONEDITIONABLE procedure sp_main_target(iv_req_id IN VARCHAR)
is
lv_count number(10);
begin
for r in(--should I select request id from staging table)loop
select count(1) into lv_count from staging where req_id = iv_req_id;
if lv_count > 0 then
dbms_output.put_line('Insertion into target table');
MERGE INTO target_tab t
   USING (SELECT key_id, inv_id, i_name, req_id FROM staging
   WHERE req_id = iv_req_id) S
   ON (t.inv_id = S.inv_id)
   WHEN MATCHED THEN UPDATE SET 
   t.key_id = s.key_id,
   t.i_name = s.i_name,
   t.req_id = s.req_id


   WHEN NOT MATCHED THEN INSERT (t.key_id,t.inv_id,t.i_name,t.req_id)
     VALUES (s.key_id,s.inv_id,s.i_name,s.req_id);
else
dbms_output.put_line('Request id is not available');
end if;
commit;
end sp_main_target;

I want to give multiple input parameters for iv_request_id and then have to process each request-id individually. How to achieve this? How will I implement multiple input parameters in comma separated?

You can use VARRAY:

create or replace procedure sp_main_target(iv_req_id IN sys.OdciNumberList)
is
lv_count number(10);
begin
for v_i in 1..iv_req_id.count loop
select count(1) into lv_count from staging where req_id = iv_req_id(v_i);
if lv_count > 0 then
dbms_output.put_line('Insertion into target table');
MERGE INTO target_tab t
   USING (SELECT key_id, inv_id, i_name, req_id FROM staging
   WHERE req_id = iv_req_id(v_i)) S
   ON (t.inv_id = S.inv_id)
   WHEN MATCHED THEN UPDATE SET
   t.key_id = s.key_id,
   t.i_name = s.i_name,
   t.req_id = s.req_id
   WHEN NOT MATCHED THEN INSERT (t.key_id,t.inv_id,t.i_name,t.req_id)
     VALUES (s.key_id,s.inv_id,s.i_name,s.req_id);
else
dbms_output.put_line('Request id is not available');
end if;
end loop;
commit;
end sp_main_target;
/

@solomon-yakobson Can we do this using for loop cursor?

Solomon Yakobson

We could but why call SQL from PL/SQL if all can be done in PL/SQL?

create or replace procedure sp_main_target(iv_req_id IN sys.OdciNumberList)
is
lv_count number(10);
begin
for v_rec in (select * from table(iv_req_id)) loop
select count(1) into lv_count from staging where req_id = v_rec.column_value;
if lv_count > 0 then
dbms_output.put_line('Insertion into target table');
MERGE INTO target_tab t
   USING (SELECT key_id, inv_id, i_name, req_id FROM staging
   WHERE req_id = v_rec.column_value) S
   ON (t.inv_id = S.inv_id)
   WHEN MATCHED THEN UPDATE SET
   t.key_id = s.key_id,
   t.i_name = s.i_name,
   t.req_id = s.req_id
   WHEN NOT MATCHED THEN INSERT (t.key_id,t.inv_id,t.i_name,t.req_id)
     VALUES (s.key_id,s.inv_id,s.i_name,s.req_id);
else
dbms_output.put_line('Request id is not available');
end if;
end loop;
commit;
end sp_main_target;
/

@solomon-yakobson Actually this stored procedure I am going to invoke from the front end so will this work? Front end wherein I will provide the request-id and process will happen. Or do we have to use connect by caluse for comma-separated inputs?

Solomon Yakobson

Front end is very generic statement? Is it Java, .Net, perl, python....? Anyway, you can use OracleArray in JDBC.

@solomon-yakobson Thanks. Got it
