Hi Rani,
I see one issue in the Q2 with the where statement:
and pv.segment1=(pv.segment1=:VENDOR_NUM or pv.vendor_name=:VENDOR_NAME)
the right one should be
and pv.vendor_id = :VEN_VENDOR_ID
the variable VEN_VENDOR_ID you have to select from the first query Q1. Add here after select
pv.vendor_id VEN_VENDOR_ID,
Regarding the other question about the data types, well, number and varchar2 is fine, perhaps char also, but go with varchar2 instead.
One last note: you should not mix uppercase and lowercase, keep it clear and structured, check your element names and values.
Best Regards
