Design and Development

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


This component carries out the action on the specified table according to the output schema defined in the ELT Mapper.


This component executes the SQL Insert, Update or Delete statement to the Vertica database.

tELTVerticaOutput Properties

Component Family


Basic settings

Action on data

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

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

  • Update: Updates entries in the table.

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


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. The schema is either Built-In or stored remotely in the Repository.

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


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.


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.


Sync columns

Click this button to retrieve the schema from the previous component connected in the Job.


Where clauses (for UPDATE and DELETE only)

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

This field is available only when Update or Delete is selected from the Action on data drop-down list.


Default Table Name

Type in the default table name.


Default Schema Name

Type in the default schema name.


Use different table name

Select this check box to use a different output table name.


Table name

Type in the output table name.

This field is available only when the Use different table name check box is selected.

Advanced settings


Select this check box to write the data directly to disk, bypassing memory.

This check box is not visible when the Set SQL Label check box is selected.


Set SQL Label

Select this check box and specify the label that identifies the query. For more information, see How to label queries for profiling.

This check box is not visible when the Direct check box is selected.


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

NB_LINE: the number of rows processed. 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.


tELTVerticaOutput is used along with the tELTVerticaMap. 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 information.


If you are using a subscription-based version of the Studio, the activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User Guide.

For more information on the log4j logging levels, see the Apache documentation at
