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

The Standard tELTPostgresqlOutput component belongs to the ELT family.

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

Basic settings

Action on data

On the data of the table defined, you can perform the following operation:

Insert: Add new entries to the table. If duplicates are found, Job stops.

Update: Updates entries in the table.

Delete: Deletes the entries which correspond to the entry flow.

Schema and Edit schema

A schema is a row description, that is to say, it defines the number of fields to be processed and passed on to the next component. The schema is either built-in or remotely stored 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: The schema is created and stored locally for this component only. Related topic: see Talend Studio User Guide.


Repository: The schema already exists and is stored in the Repository, hence can be reused. Related topic: see Talend Studio User Guide.

Where clauses for (for UPDATE and DELETE only)

Enter a clause to filter the data to be updated or deleted during the update or delete operations.

Default Table Name

Enter the default table name between double quotation marks.

Default Schema Name

Enter the default schema name between double quotation marks

Table name from connection name is variable

Select this check box when the name of the connection to this component is set to a variable, such as a context variable.

Use different table name

Select this check box to enter a different output table name, between double quotation marks, in the Table name field which appears.


Specify the metadata mapping file for the database to be used. The metadata mapping file is used for the data type conversion between database and Java. For more information about the metadata mapping, see the related documentation for Type mapping.
Note: You can use Hive mapping to support Databricks Delta Lake.

Advanced settings

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at a Job level as well as at each 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.

NB_LINE_INSERTED: the number of rows inserted. 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

tELTPostgresqlOutput is to be used along with the tELTPostgresqlMap. Note that the Output link to be used with these components must correspond strictly to the syntax of the table name.


Note that the ELT components do not handle actual data flow but only schema information.
