I have installed Oracle 21c Express Edition in my laptop with Windows 10 (x64).
Configured ODBC Driver (x64) 'Oracle in OraDB21Home1' successfully (under System DSN & User DSN tabs).
Details are as follows (standard):
Data Source Name: XE
TNS Service Name: LISTENER_XE
User ID: System
When clicked Test Connection button, it confirmed connection.
What should be the connection string in this case ?
Kindly advise if more details required.
