    • the listening port number
    • the database name
    • the user name and password for your database authentication
  3. Set the Schema as Built-In and click Edit schema to define the desired schema. The schema editor opens. Click the [+] button to add three rows of String type and give the name id, Phone, Email to the columns. Click OK to close the schema editor.
  4. In the Table Name field, type in the name of the database table, customers in this case.
  5. In the Query box, enter the query required to retrieve the desired columns from the table, id, Phone, Email in this example.
