@Anupriya you mentioned your table was an extension of a cmdb table: cmdb_ci_computer. Have you looked at the CI Class Manager to get this information? You should be able to click "Hierarchy" and find your table, from there navigate to the "Attributes" tab and you'll see selections for Derived and Added fields:
My way to see the added fields is to check the schema map for the table. The link circled in the snapshot in the attachment will give you the list of fields being created, not inherited.
