tPostgresqlOutputBulk Standard properties - 7.3

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.

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 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.

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.

For more information, see the related description of retrieving table schemas in Talend Studio User Guide.

Row separator

String (ex: "\n"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.

Enable parallel execution

Note that when parallel execution is enabled, it is not possible to use global variables to retrieve return values in a subJob.

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.

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 rule

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