tFileOutputDelimited Standard properties – Docs for ESB 6.x

tFileOutputDelimited Standard properties

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

The Standard
tFileOutputDelimited component belongs to the File family.

The component in this framework is generally available.

Basic settings

Property type

Either Built-In or Repository.


Built-In: No property data stored centrally.


Repository: Select the repository file where the
properties are stored.

Use Output Stream

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

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
hand writing, 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

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

File name

Name or path to the output file and/or the variable
to be used.

This field becomes unavailable once you have
selected the Use Output Stream check

For further information about how to define and use a
variable in a Job, see
Talend Studio

User Guide.

Row Separator

The separator used to identify the end of a row.

Field Separator

Enter character, string or regular expression to separate fields for the transferred


Select this check box to add the new rows at the end
of the file.

Include Header

Select this check box to include the column header to
the file.

Compress as zip file

Select this check box to compress the output file in
zip format.

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.

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.


Built-In: You create and store the
schema locally for this component only. Related topic: see
Talend Studio

User Guide.


Repository: You have already created
the schema and stored it in the Repository. You can reuse it in various projects and
Job designs. Related topic: see
Talend Studio

User Guide.

Sync columns

Click to synchronize the output file schema with the
input file schema. The Sync function only displays once the Row connection is linked with the output

Advanced settings

Advanced separator (for numbers)

Select this check box to change the separator used for numbers. By default, the thousands separator is a comma (,) and the decimal separator is a period (.).

Thousands separator: define separators
for thousands.

Decimal separator: define separators for

CSV options

Select this check box to specify the following CSV parameters:

  • Escape char: enter the escape character between double
    quotation marks. For example, you need to type in "\" if the
    backslash character () is used as the escape character.

  • Text enclosure: enter the enclosure character (only one
    character) between double quotation marks. For example, """
    needs to be entered when double quotation marks (“) are used as the enclosure

Create directory if not exists

This check box is selected by default. It creates the directory
that holds the output delimited file, if it does not already exist.

Split output in several files

In case of very big output files, select this check box to
divide the output delimited file into several files.

Rows in each output file: set the number
of lines in each of the output files.

Custom the flush buffer size

Select this check box to define the number of lines to write
before emptying the buffer.

Row Number: set the number of lines to

Output in row mode

Select this check box to ensure atomicity of the flush so that
each row of data can remain consistent as a set and incomplete rows of data are
never written to a file.

This check box is mostly useful when using this component in
the multi-thread situation.


Select the encoding from the list or select Custom and define it manually. This field is compulsory for database
data handling.

Don’t generate empty file

Select this check box if you do not want to generate empty

Throw an error if the file already exist

Select this check box to throw an exception if the output file specified in the
File Name field on the Basic
view already exists.

Clear this check box to overwrite the existing file.

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

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

FILE_NAME: the name of the file being processed. This is
a Flow variable and it returns a string.

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 +
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
a delimited file and separate fields using a field separator value.
