JDBC connection without database definition

I have a class which connects to MySQL database. I want to make it more universal. I'm not sure in myself. My class can connect any server if you specify the database name.

String url="jdbc:mysql://"+host+":"+port+"/"+dbname;

How can I connect without the specifying the database name (to use create database command for example)? Is it correct to use:

String url="jdbc:mysql://"+host+":"+port

Or does it use a different syntax?

Solution

  • Yes, you can use String url="jdbc:mysql://"+host+":"+port but during the execution of query you need to specify the database name as 

    select * from dbname.table
