Function

tSPSSStructure retrieves information about the variables inside .sav files.

Purpose

tSPSSStructure addresses variables inside .sav files. You can use this component in combination with tFileList to gather information about existing *.sav files to further analyze or check the findings.

Basic settings

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.

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

The schema metadata in this component is predefined and thus read-only. It is based on the internal SPSS convention. You can click Edit schema to view the predefined metadata.

 

 

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 .sav file to be processed.

Advanced settings

tStatCatcher Statistics

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

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

Use this component as a start component. It needs an output 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>:\program\SPSS, 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.

Log4j

If you are using a subscription-based version of the Studio, the activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User Guide.

For more information on the log4j logging levels, see the Apache documentation at http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html.

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.
