tInformixOutputBulk – Docs for ESB 5.x

Component family

Databases/Informix

Function

Writes a file composed of columns, based on a defined delimiter
and on Informix standards.

Purpose

Prepares the file to be used as a parameter in the INSERT query
used to feed Informix databases.

Basic settings

Property type

Either Built-in or
Repository.

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

Built-in: No property data stored
centrally

Repository: Select the repository
file in which the properties are stored. The fields that follow are
completed automatically using the data retrieved.

File Name

Name of the file to be generated.

Append

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

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.

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

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.

When the schema to be reused has default values that are integers or functions, ensure that
these default values are not enclosed within quotation marks. If they are, you must remove
the quotation marks manually.

For more details, see https://help.talend.com/display/KB/Verifying+default+values+in+a+retrieved+schema.

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

Advanced settings

Row separator

String (ex: ”
“on Unix) to distinguish rows.

Field separator

Character, string or regular expression used to separate
fields

Set DBMONEY

Select this box if you want to define the decimal separator in the
corresponding field.

Set DBDATE

Select the date format that you want to apply.

Create directory if not exists

This check box is selected automatically. The option allows you to
create a folder for the output file if it doesn’t already
exist.

Custom the flush buffer size

Select this box in order to customize the memory size used to
store the data temporarily. In the Row
number field enter the number of rows at which point
the memory should be freed.

Encoding

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

tStatCatcher Statistics

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

Dynamic settings

Click the [+] button to add a row in the table and fill
the Code field with a context variable to choose your
database connection dynamically from multiple connections planned in your Job. This feature
is useful when you need to access database tables having the same data structure but in
different databases, 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.

Once a dynamic parameter is defined, the Component List
box in the Basic settings view becomes unusable.

For more information on Dynamic settings and context
variables, see Talend Studio User Guide.

Global Variables 

NB_LINE: the number of rows processed. 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

This component is generally used along with tInformixBulkExec. Together, they improve
performance levels when adding data to an Informix database.

Log4j

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.

Due to license incompatibility, one or more JARs required to use this component are not
provided. You can install the missing JARs for this particular component by clicking the
Install button on the Component tab view. You can also find out and add all missing JARs easily on
the Modules tab in the Integration perspective
of your studio. For details, see https://help.talend.com/display/KB/How+to+install+external+modules+in+the+Talend+products
or the section describing how to configure the Studio in the Talend Installation and Upgrade
Guide.
