tELTVerticaMap – Docs for ESB 7.x


Builds the SQL SELECT statement using the table schema(s) provided by one or more
tELTVerticaInput components.

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

tELTVerticaMap Standard properties

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

The Standard
tELTVerticaMap component belongs to the ELT family.

The component in this framework is available in all Talend

Basic settings

DB Version

Select the version of the Vertica database being used.

Use an existing connection

Select this check box and in the Component List click the relevant connection component to
reuse the connection details you already defined.

Note: When a Job contains the parent Job and the child Job, if you
need to share an existing connection between the two levels, for example, to share the
connection created by the parent Job with the child Job, you have to:

  1. In the parent level, register the database connection
    to be shared in the Basic
    view of the connection component which creates that very database

  2. In the child level, use a dedicated connection
    component to read that registered database connection.

For an example about how to share a database connection
across Job levels, see

ELT Vertica Map Editor

The ELT Map editor allows you to define the output schema as well as
build graphically the SQL statement to be executed. The column names of
the schema can be different from the column names in the

Style link

Select a way in which links are displayed.

  • Auto: By default, the links
    between the input and output schemas and the Web service
    parameters are in the form of curves.

  • Bezier curve: The links between
    the schema and the Web service parameters are in the form of

  • Line (fastest): The links
    between the schema and the Web service parameters are in the
    form of straight lines.

    This option slightly optimizes performance.

Property Type

Either Built-In or Repository.


Built-In: No property data stored


Repository: Select the repository
file in which the properties are stored. The database connection fields
that follow are completed automatically using the data retrieved.


Type in the IP address or hostname of the database.


Type in the listening port number of the database.


Type in the name of the database you want to use.

Additional JDBC Parameters

Specify additional connection properties for the database connection
you are creating.

Username and Password

Type in the database 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.

Advanced settings

tStatCatcher Statistics

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

Global Variables

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.


Usage rule

tELTVerticaMap is used along with
tELTVerticaInput and tELTVerticaOutput. Note that the Output link
to be used with these components must correspond strictly to the syntax
of the table name.


The ELT components do not handle actual data flow but only schema
