tSPSSOutput

Writes or appends data to an SPSS .sav file. It creates SPSS files on the fly and
overwrites existing ones.

tSPSSOutput writes data entries in an .sav
file.

tSPSSOutput Standard properties

These properties are used to configure tSPSSOutput running in the Standard Job framework.

The Standard
tSPSSOutput component belongs to the Business Intelligence family.

The component in this framework is generally available.

Basic settings

Sync schema

Click this button to synchronize with the columns of the SPSS .sav file.

Schema and Edit Schema

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

Click Edit schema 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] window.

 

Built-in: The schema is created and stored
locally for this component only. Related topic: see
Talend Studio User
Guide.

 

Repository: The schema already exists and is
stored in the Repository, hence can be reused. Related topic: see
Talend Studio User
Guide.

Filename

Name or path of the SPSS .sav file to be written.

Write Type

Select an operation from the list:

Write: simply writes the new data.

Append: writes the new data at the end of the
existing data.

Advanced settings

tStat
Catcher Statistics

Select this check box to collect log data at the component level.

Global Variables

Global Variables

NB_LINE: the number of rows read by an input component or
transferred to an output component. This is an After variable and it returns an
integer.

ERROR_MESSAGE: the error message generated by the
component when an error occurs. This is an After variable and it returns a string. This
variable functions only if the Die on error check box is
cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable
functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl +
Space to access the variable list and choose the variable to use from it.

For further information about variables, see
Talend Studio

User Guide.

Usage

Usage rule

This component can not be used as start component. It requires an input
flow.

Warning:

Before being able to benefit from all functional objectives of the SPSS
components, make sure to do the following: -If you have already installed SPSS,
add the path to the SPSS directory as the following: SET
PATH=%PATH%;<DR>:programSPSS, or -If you have not installed
SPSS, you must copy the SPSS IO “spssio32.dll” lib from the SPSS installation CD
and paste it in
Talend
 root directory.

Limitation

Oracle provides two kinds of JVM platforms (32-bit and 64-bit). By default, the
JVM used in a 64-bit operating system is the 64-bit version of the JVM. Since the
JSPSS.dll file used by this component is compiled in the 32-bit JVM, it is needed to
configure the 32-bit JVM for Job execution in
Talend Studio

installed on a 64-bit operating system.

To do so, perform the following:

  1. Open the relevant Job in the workspace.

  2. Click the Run tab and enter the Advanced settings view.

  3. Select the Use specific JVM arguments check
    box and click the New… button.

  4. In the Set the VM argument box, enter
    -d32 and click Ok for
    validation.

Scenario: Writing data in an .sav file

This Java scenario describes a very simple Job that writes data entries in an .sav
file.

Setting up the Job

  1. Drop a tRowGenerator component and a tSPSSOutput component from the Palette onto the design workspace.
  2. Right-click on tRowGenerator and connect it to
    tSPSSOutput using a Main
    Row     link.

Configuring the input component

  1. In the design workspace, double click tRowGenerator
    to display its Basic Settings view and open its editor.
    Here you can define your schema.

  2. Click the plus button to add the columns you want to write in the .sav file.
  3. Define the schema and set the parameters to the columns.

    Warning:

    Make sure to define the length of your columns. Otherwise, an error
    message will display when building your Job.

  4. Click OK to validate your schema and close the
    editor.

Configuring the output component

  1. Click tSPSSOutput to display its Basic settings view and define the component properties.

    Use_Case_tSPSSOutput3.png

  2. Click the three-dot button next to the Filename
    field and browse to the SPSS .sav file in which you want to write data.
  3. Click the three-dot button next to Sync columns to
    synchronize columns with the previous component. In this example, the schema to be
    inserted in the .sav file consists of the two columns: id and
    country.
  4. If required, click Edit schema to view/edit the
    defined schema.
  5. From the Write Type list, select Write or Append to simply
    write the input data in the .sav file or add it to the end of the .sav file.

Job execution

Save the Job and press F6 to execute it.

The data generated by the tRowGenerator component is
written in the defined .sav file.
