Write excel 2007 file format (xlsx)

Select this check box to write the processed data into the
.xlsx format of Excel 2007.

Use Output Stream

Select this check box process the data flow of interest. Once you
have selected it, the Output Stream
field displays and you can type in the data flow of interest.

The data flow to be processed must be added to the flow in order
for this component to fetch these data via the corresponding
representative variable.

This variable could be already pre-defined in your Studio or
provided by the context or the components you are using along with
this component; otherwise, you could define it manually and use it
according to the design of your Job, for example, using tJava or tJavaFlex.

In order to avoid the inconvenience of writing manually, you could
select the variable of interest from the auto-completion list
(Ctrl+Space) to fill the
current field on condition that this variable has been properly
defined.

For further information about how to use a stream, see Scenario 2: Reading data from a remote file in streaming mode.

Schema and Edit
Schema

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.

This component offers the
advantage of the dynamic schema feature. This allows you to retrieve unknown columns
from source files or to copy batches of columns from a source without mapping each
column individually. For further information about dynamic schemas, see
Talend Studio

User Guide.

This dynamic schema
feature is designed for the purpose of retrieving unknown columns of a table and is
recommended to be used for this purpose only; it is not recommended for the use of
creating tables.

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 will be
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 in
various projects and Job designs. Related topic: see

Talend Studio User
Guide.

Create directory if not exists

This check box is selected by default. This option creates the
directory that will hold the output files if it does not already

Recalculate formula

Select this check box if you need to recalculate formula(s) in the

This check box appears only when you select all these three check
boxes: Write excel2007 file

sheet.

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at a
Job level as well as at each 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 rule

Use this component to write an MS Excel file with data passed on
from other components using a Row
link.

Dynamic settings

Click the [+] button to add a row in the
table and fill the Code field with a context variable
to choose your HDFS connection dynamically from multiple connections planned in your
Job. This feature is useful when you need to access files in different HDFS systems or
different distributions, especially when you are working in an environment where you
cannot change your Job settings, for example, when your Job has to be deployed and
executed independent of
Talend Studio
.

The Dynamic settings table is
available only when the Use an existing
connection check box is selected in the Basic settings view. Once a dynamic parameter is
defined, the Component List box in the
Basic settings view becomes unusable.

For examples on using dynamic parameters, see Scenario: Reading data from databases through context-based dynamic connections and Scenario: Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic
settings and context variables, see
Talend Studio User Guide.
