How To Connect To Xampp Server And Create New Mysql Database Using Netbeans – Java JDBC – Source Code

To connect to xampp server using java programming language and netbeans IDE (integrated development environment), you need to download MySQL Connector/J. Then extract the zipped connector file and add the jar file to the project libraries. Make sure you start Apache and mysql in Xampp. If the database you are trying to create already exixts, make sure you drop it. This code connects to Xampp server and creates new database. First the code checks if the database exists, If it doesn’t, then its created.

                System.out.println("Database creation query - " + createNewDatabase);
                //Execute database creation query and store the result in integer variable. Expected reults are 0 and 1.
                int createdb = stmt.executeUpdate(createNewDatabase);
                if (createdb > 0) {
                    System.out.println(dbName + " Created Successfully");
                }

        } catch (SQLException ex) {
            System.out.println("Error " + ex.getMessage());
        }

    }

}

After you run the above Java code you get the following output.

run:
Driver Loaded
Connected To Server Successfully
Check if database exists query - SELECT SCHEMA_NAME FROM `information_schema`.`SCHEMATA` WHERE `SCHEMA_NAME` = 'products_db2'
Result Set Value false
Database creation query - CREATE DATABASE IF NOT EXISTS products_db2
products_db2 Created Successfully
