Populate 1 table based on another table

Question

I have a "VISITOR_TRACKER" application with the following 2 tables:
VISITORS (table)
VISITOR_ID (pk)
F_NAME
L_NAME
VISITOR_DETAILS (table)
V_DETAILS_ID (pk)
V_TIME_IN
V_DESTINATION
I want to do the following:
1. The visitor types in his/her last name in a search box.
2. Everyone with that last name shows up in either a report or a drop-down select list. The visitor selects his/her name.
3. A form "displays only" the name selected and has 2 text fields for the customer to enter their DESTINATION and TIME_IN and presses the submit button.
How do I set this up? The problem I'm encountering is that if I create a form w/report off of the VISITORS table, I'm unable to populate the DESTINATION and TIME-IN because the F_NAME and L_NAME from the VISITORS table is already popluted - it is trying to populate twice.
I tried basing the form w/report off of the VISITOR_DETAILS table but my report shows only the names that have any records in VISITOR_DETAILS. Also, the form shows the details of the VISITOR_DETAILS record that was selected.
My report query looks like this:
select "VISITOR_DETAILS"."V_DETAILS_ID" as "V_DETAILS_ID",
"VISITOR_DETAILS"."VISITOR_ID_LU" as "VISITOR_ID_LU",
"VISITORS"."F_NAME" || ' ' || "VISITORS"."L_NAME" as "NAME"
from "VISITOR_DETAILS" "VISITOR_DETAILS",
"VISITORS" "VISITORS"
where "VISITOR_ID_LU" = "VISITOR_ID"
I prefer to have a drop-down select list instead of a report if possible.
Please help! I have been working HOURS on this?

Answer 1

if you only want a duplicat of the structure and don't worry about constraints, indexes, triggers etc you could use something like this
create table emp_dup as
select * from emp
where 1=0;Another more flexible way is to use the package DBMS_METADATA
