I was using a SQuirrel SQL Client to connect & browse my oracle database servers. I have given the credentials in the connection URL itself. But it still prompts for the username and password. Does it really required to provide additional username/password while establishing connection. Won't it take it from the connection URL?
jdbc:oracle:thin:username/password@my.oracle.server.domain.com:1521:DBName
Thin driver Oracle's JDBC Thin driver uses Java sockets to connect directly to Oracle. It provides its own TCP/IP version of Oracle's SQL*Net protocol. Because it is 100% Java, this driver is platform independent and can also run from a Web Browser (applets). There are 2 URL syntax, old syntax which will only work with SID and the new one with Oracle service name.
Old syntax
jdbc:oracle:thin:@[HOST][:PORT]:SID
New syntax
jdbc:oracle:thin:@//[HOST][:PORT]/SERVICE
On new syntax SERVICE may be a oracle service name or a SID.
There are also some drivers that support a URL syntax which allow to put Oracle user id and password in URL.
jdbc:oracle:thin:[USER/PASSWORD]@[HOST][:PORT]:SID
jdbc:oracle:thin:[USER/PASSWORD]@//[HOST][:PORT]/SERVICE

Refer to this link, it will help you.

For example, if you want to include username & password in the Postgres connection string.
jdbc:postgresql://postgres-10.4.cluster:5432/default?user=postgres&password=postgres
Won't it take it from the connection URL?
I think No
You need to enter usrename & password.

section Connecting
From what I have seen, support for passing the username/password in the JDBC URL is inconsistent across Oracle JDBC Drivers.
