Schema and Edit

A schema is a row description, it defines the number of fields to
be processed and passed on to the next component. The schema is
either Built-in or stored remotely
in the Repository.

Click Edit
to make changes to the schema. If the current schema is of the Repository type, three options are available:

  • View schema: choose this
    option to view the schema only.

  • Change to built-in property:
    choose this option to change the schema to Built-in for local changes.

  • Update repository connection:
    choose this option to change the schema stored in the repository and decide whether
    to propagate the changes to all the Jobs upon completion. If you just want to
    propagate the changes to the current Job, you can select No upon completion and choose this schema metadata
    again in the Repository Content


Built-in: You create the schema
and store it locally for the relevant component. Related topic: see

Repository: You have already
created the schema and stored it in the Repository. You can reuse it
in various projects and job flowcharts. Related topic: see

Usage rule

This component is generally used as a Start component. It must be
linked to an output component.

Getting country names using tWebServiceInput

This scenario describes a two-component Job which uses a Web service method to obtain
the country name corresponding to a given country code and displays the output on the
Run console view.

Getting country names using tWebServiceInput

  1. Drop a tWebServiceInput component and a
    tLogRow component from the Palette onto the design workspace.
  2. Link the two components using a Row >
    Main connection.


  3. Double-click the tWebServiceInput component
    to open its Basic settings view.


  4. Click the […] button next to Edit schema to open the Schema dialog box and define the schema for the response from
    the Web service.

    In this example, the schema is composed of only one column: Result.

  5. In the WSDL field, specify the WSDL URL of
    the Web service to be used, http://www.webservicex.net/country.asmx?WSDL in this
  6. If you are using a proxy server, select the Use http
    check box and enter the necessary connection
  7. In the Method name field, enter the method to
