tELTPostgresqlInput – Docs for ESB 5.x



tELTPostgresqlInput properties

The three ELT Postgresql components are closely related, in terms of their operating
conditions. These components should be used to handle Postgresql DB schemas to generate
Insert statements, including clauses, which are to be executed in the DB output table

Component family




Provides the table schema to be used for the SQL statement to


Allows you to add as many Input tables as required for the most
complicated Insert statement.

Basic settings

Schema and Edit

A schema is a row description, it defines the nature and number of
fields to be processed. The schema is either built-in or remotely
stored in the Repository. The Schema defined is then passed on to
the ELT Mapper to be included to the Insert SQL statement.

Since version 5.6, both the Built-In mode and the Repository mode are
available in any of the Talend solutions.

Click Edit schema to make changes to the schema. If the
current schema is of the Repository type, three options are

  • 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

  • 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



Built-in: The schema is created
and stored locally for this component only. Related topic: see
Talend Studio User



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

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

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 +
to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio
User Guide.


tELTPostgresqlInput 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.
