Hi Andy,
I created a collection by using this
My schema:
CREATE TABLE bill
(id NUMBER NOT NULL,
fruit VARCHAR2(128),
quantity NUMBER)
-- Constraints for BILL
ALTER TABLE bill
ADD CONSTRAINT bill_pk PRIMARY KEY (id)
-- Add sequence to generate PK
CREATE SEQUENCE bill_seq
-- Triggers for BILL
CREATE OR REPLACE TRIGGER bill_trg
BEFORE
INSERT
ON bill
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
BEGIN
SELECT BILL_SEQ.NEXTVAL INTO :NEW.ID FROM DUAL;
END;
I use one page
On this page I created 2 regions
1. Html Region with only one button with submmit "CREATE BILL"
2. Report region with One report, one button "Add line" and second botton "Save"
Report source:
select HTMLDB_ITEM.HIDDEN(1,SEQ_ID), HTMLDB_ITEM.TEXT(2,a.c001) c001, HTMLDB_ITEM.TEXT(3,a.c002) c002
FROM wwv_flow_collections a
where a.collection_name = 'COLL_BILL'
Condition
PL/SQL Function body returning a Boolen
begin
if htmldb_collection.collection_exists('COLL_BILL') then
return true;
else
return false;
end if;
end;
3. PLSQL Process
BEGIN
htmldb_collection.create_or_truncate_collection
(p_collection_name => 'COLL_BILL');
end;
Condition
When Button Pressed
"CREATE BILL"
4. PLSQL Process
begin
for i in 1.. HTMLDB_APPLICATION.G_F01.count loop
htmldb_collection.UPDATE_MEMBER (
p_collection_name=> 'COLL_BILL',
p_seq => HTMLDB_APPLICATION.G_F01(i),
p_c001 => HTMLDB_APPLICATION.G_F02(i),
p_c002 => HTMLDB_APPLICATION.G_F03(i)
end loop;
htmldb_collection.add_member
(p_collection_name => 'COLL_BILL',
p_c001 => null,
p_c002 => null
end;
Condition
When Button Pressed
"Add line"
5. PLSQL Process
begin
for i in 1.. HTMLDB_APPLICATION.G_F01.count loop
insert into BILL (fruit, quantity)
values
(HTMLDB_APPLICATION.G_F02(i), HTMLDB_APPLICATION.G_F03(i));
end loop;
HTMLDB_COLLECTION.DELETE_COLLECTION ('COLL_BILL');
end;
Condition
When Button Pressed
"Save"
