Hi Rehan,
To get the JOIN conditions applied in a view, you can use the system view CS_JOIN_CONDITIONS.
It will also tell you the type of JOIN applied along with the tables/columns.
Here is a sample query:
SELECT VIEW_NAME, TABLE_NAME1, COLUMN_NAME1,TABLE_NAME2, COLUMN_NAME2, JOIN_TYPE
FROM CS_JOIN_CONDITIONS
WHERE VIEW_NAME = 'YOUR_VIEW_NAME'
