VBA - Updating Excel values to a Database

Dear all,

I need your help in writing a Macro to update a Oracle SQL database based on the values in an excel sheet.

Please assume the Oracle database details as below:
-------------------------------------------
Hostname : 1.2.3.4
Port : 1234
SID : DBUPDATE
Username : abc
Password : abc
--------------------------------------------

Table Name : employee_details

Table details:

emp_id, emp_name
1 -
2 -
---------------------------------------------

The content of excel sheet are as follows:

emp_id emp_name
1 a
2 b

----------------------------------------------

Could you please help with the VB Script to update emp_name in Oracle database based on entries in the excel sheet?

Thanks,
Vinod Krishna
