need form to retrieve data and update data 2.3.9

I like to create 2 forms

1. Enter Data and create a table
2. Update Data if existing data exist in the same table

Ideally it should be in the same form , data can be retrieved via a field name (or part of it through a SQL search)

my existing chronoform is 2.3.9

I can do it for you. You can hire me.

thanks
