tAccessOutputBulk – Docs for ESB 7.x

tAccessOutputBulk

Prepares the file which contains the data used to feed the Access
database.

The tAccessOutputBulk and
tAccessBulkExec components are generally used together to output
data to a delimited file and then to perform various actions on the file in an Access
database, in a two step process. These two steps are fused together in the
tAccessOutputBulkExec component, detailed in a separate section.
The advantage of using a two step process is that it makes it possible to carry out
transformations on the data before loading it in the database.

tAccessOutputBulk writes a delimited file.

tAccessOutputBulk Standard properties

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

The Standard
tAccessOutputBulk component belongs to the Databases family.

The component in this framework is available in all Talend
products
.

Note: This component is a specific version of a dynamic database
connector. The properties related to database settings vary depending on your database
type selection. For more information about dynamic database connectors, see Dynamic database components.

Basic settings

Database

Select a type of database from the list and click
Apply.

Property type

Either Built-in or
Repository
.

 

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 and path to the file to be created and/or the variable to be
used.

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

User Guide.

Create directory if not exists

Select this check box to create the as yet non-existant file
directory that specified in the File
name
field.

Append

Select this check box to add any new rows to the end of the
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. When you create a Spark
Job, avoid the reserved word line when naming the
fields.

 

Built-In: You create and store the schema locally for this component
only.

 

Repository: You have already created the schema and stored it in the
Repository. You can reuse it in various projects and Job designs.

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.

You can find more details about how to
verify default values in retrieved schema in Talend Help Center (https://help.talend.com).

 

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.

Advanced settings

Include header

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

Encoding

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

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 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

Usage rule

This component is to be used along with tAccessBulkExec component. Used together they offer
gains in performance while feeding an Access database.

Component family

Databases/Access

Limitation

If you are using an ODBC driver, you need to work with Java 7, and make sure that your JVM
and ODBC versions match up: both 64-bit or 32-bit.

When working with Java 8, this component supports only the General collation mode of
Access.
