Apex Manual tabular form

Question

Hi friends,
I am new to Apex and am making a timesheet application. I have 2 main tables which I am using and their structures are as follows:
TB_OPMI_PROJ_ACT_MAP:
PROJ_REF VARCHAR2
REL_ID VARCHAR2
ACT_CODE VARCHAR2
TB_OPTI_EMP_TS:
PROJ_REF VARCHAR2
REL_ID VARCHAR2
EMP_ID VARCHAR2
ACT_CODE VARCHAR2
TS_WDI NUMBER
TS_WD2 NUMBER
TS_WD3 NUMBER
TS_WD4 NUMBER
TS_WD5 NUMBER
TS_WD6 NUMBER
TS_WD7 NUMBER
TS_REMARKS VARCHAR2
TS_STATUS VARCHAR2
Now I have to create a manual tabular form based on data from these 2 tables and either insert or update data into the timesheet table.
The page structure is such that I have created page items for emp_id, proj_ref and rel_id(all are LOV’s). And there is a button that submits the page. So when the user inputs the data and clicks on submit, the report whose source code is as follows shows up with data from both tables:
DECLARE
v_query varchar2(10000);
BEGIN
IF :P7_RELEASE_ID is not null THEN
v_query := 'SELECT b.act_code activities,
apex_item.text (1, a.ts_wd1, 10, 10) monday,
apex_item.text (2, a.ts_wd2, 10, 10) tuesday,
apex_item.text (3, a.ts_wd3, 10, 10) wednesday,
apex_item.text (4, a.ts_wd4, 10, 10) thursday,
apex_item.text (5, a.ts_wd5, 10, 10) friday,
apex_item.text (6, a.ts_wd6, 10, 10) saturday,
apex_item.text (7, a.ts_wd7, 10, 10) sunday,
apex_item.text (8, a.ts_remarks, 70, 128) remarks
from tb_opti_emp_ts a, tb_opmi_proj_act_map b
WHERE a.proj_ref = b.proj_ref
AND a.rel_id = b.rel_id
AND a.act_code = b.act_code
AND a.emp_id = '''||:P7_EMPLOYEE||'''
AND b.rel_id = '''||:P7_RELEASE_ID||'''
AND a.proj_ref = '''||:P7_PROJ_REF||''';';
ELSE
v_query := 'SELECT 1 FROM dual WHERE 1=0';
END IF;
return(v_query);
END;
Now this query is working fine. The data in the tb_opmi_proj_act_map is basically the activities mapped on each project reference and release id.
Now when there is no corresponding data for the emp_id,proj_ref,rel_id and act_code in the main timesheet table, even then I need to generate to a tabular form structure with all the activities listed for the input proj_ref and rel_id and the 8 respective columns for the days of the week and remarks for each row or activity. I don’t know how to progress and am stuck. I just had a thought of modifying my region source a bit something like this.
DECLARE
v_query varchar2(10000);
v_count number;
BEGIN
+Select count(*) into v_count from tb_opti_emp_ts where emp_id=P7_EMPLOYEE and proj_ref=P7 PROJREF and rel_id=P7_REL_ID;+
IF (:P7_RELEASE_ID is not null) and (v_count>0)  THEN
v_query := 'SELECT b.act_code activities,
apex_item.text (1, a.ts_wd1, 10, 10) monday,
apex_item.text (2, a.ts_wd2, 10, 10) tuesday,
apex_item.text (3, a.ts_wd3, 10, 10) wednesday,
apex_item.text (4, a.ts_wd4, 10, 10) thursday,
apex_item.text (5, a.ts_wd5, 10, 10) friday,
apex_item.text (6, a.ts_wd6, 10, 10) saturday,
apex_item.text (7, a.ts_wd7, 10, 10) sunday,
apex_item.text (8, a.ts_remarks, 70, 128) remarks
from tb_opti_emp_ts a, tb_opmi_proj_act_map b
WHERE a.proj_ref = b.proj_ref
AND a.rel_id = b.rel_id
AND a.act_code = b.act_code
AND a.emp_id = '''||:P7_EMPLOYEE||'''
AND b.rel_id = '''||:P7_RELEASE_ID||'''
AND a.proj_ref = '''||:P7_PROJ_REF||''';';
ELSIF (:P7_RELEASE_ID is null) then
v_query := 'SELECT 1 FROM dual WHERE 1=0';
else
[code for generating my requirement in case the input is legit and there is no data in the timesheet table.]
END IF;
return(v_query);
END;
Please could someone help me????
Also in either case, whether data is generated from the join if already existing or if no data exists, I need to then insert the data or update it accordingly and have no idea how to proceed.
I know the solution will be a lengthy one but please its urgent and I am stuck. Please any help would be greatly appreciated.
Thanks in advance……

Hi all,
In response to my previous post, I would like to update that I have been able to generate my required region.
Now the final query is as follows:
DECLARE
v_query varchar2(10000);
v_count number;
BEGIN
select count(*) into v_count from tb_opti_emp_ts where emp_id=:P7_EMPLOYEE and proj_ref=:P7_PROJ_REF and rel_id=:P7_RELEASE_ID;
IF ((:P7_RELEASE_ID is not null) and (v_count>0)) THEN
v_query := 'SELECT b.act_code activities,apex_item.text (1, a.ts_wd1, 10, 10) monday,apex_item.text (2, a.ts_wd2, 10, 10) tuesday,apex_item.text (3, a.ts_wd3, 10, 10) wednesday,apex_item.text (4, a.ts_wd4, 10, 10) thursday,apex_item.text (5, a.ts_wd5, 10, 10) friday,apex_item.text (6, a.ts_wd6, 10, 10) saturday,apex_item.text (7, a.ts_wd7, 10, 10) sunday,apex_item.text (8, a.ts_remarks, 70, 128) remarks from tb_opti_emp_ts a, tb_opmi_proj_act_map b WHERE a.proj_ref = b.proj_ref
AND a.rel_id = b.rel_id
AND a.emp_id = '''||:P7_EMPLOYEE||'''
AND b.rel_id = '''||:P7_RELEASE_ID||'''
AND a.proj_ref = '''||:P7_PROJ_REF||''';';
ELSIF (:P7_RELEASE_ID is null) then
v_query := 'SELECT 1 FROM dual WHERE 1=0';
else
v_query:='select (select act_desc from tb_opmi_act_code a where a.act_code=b.act_code) as activities,apex_item.text(1,null) Monday,apex_item.text(2,null) Tuesday,apex_item.text(3,null) Wednesday,apex_item.text(4,null) Thursday,apex_item.text(5,null) Friday,apex_item.text(6,null) Saturday,apex_item.text(7,null) Sunday,apex_item.text(8,null) Remarks from tb_opmi_proj_act_map b where proj_ref='''||:P7_PROJ_REF||''' and rel_id='''||:P7_RELEASE_ID||''';';
END IF;
return(v_query);
END;
Now I have created a button which have dynamic action as its on click action. Now in the dynamic action I have to write the code for inserting/updating the data in the timesheet table.
I need help with it please its urgent..........
