In Java, it's possible to establish connections to MySQL databases by specifying the database name in the connection URL. However, the question arises: "Can a MySQL database be created from Java without knowing the database name upfront, using only login credentials?"
To address this, it's worth noting that the database parameter is not mandatory in the JDBC connection string. Hence, a connection can be established without specifying a specific database.
Referencing the suggestions from online resources, such as MySQL forums and mailing lists, the following approach can be employed:
Conn = DriverManager.getConnection("jdbc:mysql://localhost/?user=root&password=rootpassword"); s = Conn.createStatement(); int Result = s.executeUpdate("CREATE DATABASE databasename");
Here, a connection is established to the MySQL server using the root username and password without specifying the database name. The executeUpdate method is used to execute a SQL statement that creates the databasename database. This approach allows you to dynamically create a MySQL database from Java using only login credentials.
