unknown database in jdbc

Question

I am using JDBC and new to it. but I keep getting this runtime exception:

   connecting to psysical database...
   com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErr         


        

Answer 1

This error occurs when server is not able to find the database. This can be due to a wrong port given in the database URL, for example

String DB_URL = "jdbc:mysql://localhost:3307/database_name"

So check this port number (3307 in the above case) with the port mentioned in the Xampp controler (go to Xampp controller and then configuration of MySql).
