tPostgresPlusOutputBulk – Docs for ESB 7.x

tPostgresPlusOutputBulk

Prepares the file to be used as parameter in the INSERT query to
feed the PostgresPlus database.

The tPostgresPlusOutputBulk writes a file with columns
based on the defined delimiter and the PostgresPlus standards.

The tPostgresplusOutputBulk and tPostgresplusBulkExec components are generally used together as part of
a two step process. In the first step, an output file is generated. In the second step,
this file is used in the INSERT operation used to feed a database. These two steps are
fused together in the tPostgresPlusOutputBulkExec
component, detailed in a separate section. The advantage of using two separate
components is that the data can be transformed before it is loaded in the database.

tPostgresPlusOutputBulk Standard properties

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

The Standard
tPostgresPlusOutputBulk 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 of the file to be generated.

Warning:

This file is generated on the local machine or a shared folder
on the LAN.

Append

Select this check box to add the new rows at 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.

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: 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).

Advanced settings

Row separator

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

Field separator

Character, string or regular expression to separate fields.

Include header

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

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.

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
integer.

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.

A Flow variable functions during the execution of a component while an After variable
functions after the execution of the component.

Usage

Usage rule

This component is to be used along with tPostgresPlusBulkExec component. Used together they
offer gains in performance while feeding a PostgresPlus
database.
