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

The Standard tPostgresPlusOutputBulkExec 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.

DB Version

List of database versions.

Host

Database server IP address.

Currently, only localhost, 127.0.0.1 or the exact IP address of the local machine is allowed for proper functioning. In other words, the database server must be installed on the same machine where the Studio is installed or where the Job using tPostgresPlusOutputBulkExec is deployed.

Port

Listening port number of DB server.

Database

Name of the database

Schema

Exact name of the schema.

Username and Password

DB user authentication data.

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

Table

Name of the table to be written. Note that only one table can be written at a time and that the table must exist for the insert operation to succeed.

Action on table

On the table defined, you can perform one of the following operations:

None: No operation is carried out.

Drop and create a table: The table is removed and created again.

Create a table: The table does not exist and gets created.

Create a table if not exists: The table is created if it does not exist.

Clear a table: The table content is deleted.

File Name

Name of the file to be generated and loaded.

Warning:

This file is generated on the machine specified by the URI in the Host field so it should be on the same machine as the database server.

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. 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 Verifying default values in a retrieved schema.

Advanced settings

Action

Select the action to be carried out

Bulk insert Bulk update Depending on the action selected, the required information varies.

File type

Select the type of file being handled.

Null string

String displayed to indicate that the value is null.

Row separator

String (ex: "\n"on Unix) to distinguish rows.

Field terminated by

Character, string or regular expression to separate fields.

Text enclosure

Character used to enclose text.

tStat Catcher Statistics

Usage

Usage rule

This component is mainly used when no particular transformation is required on the data to be loaded onto the database.

Limitation

The database server must be installed on the same machine where the Studio is installed or where the Job using tPostgresPlusOutputBulkExec is deployed, so that the component functions properly.
