Oracel-SQL Question

Hi Oracle gurus,

        I have just started using oracle, and please forgive me for this "probably" simple question:

	I am using SQL-plus for windows
	I have created a table-

	Create Table Company_Profile (
	Company_code NUMBER(4) NOT NULL,
	Date_of_Joinig DATE,
	Primary Key (Company_code) )

	Create Unique Index company_profile_index ON Company_Profile
	(Company_Code)

	The above two have succeded.
	But when I say- 

	Drop Index company_profile_index
	it gives me an error saying no such index.
	
	But I checked the table structure, by attaching this in MS-Access
	and when I check the name of the index, it is
	Username_SYS_c00345

	In other words Oracle has given a different name to the index.
	The index is not named as company_profile_index

	Can anyone shed Light on this?
	Thanks for the effort.
