tELTGreenplumInput properties

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

Component family

ELT/Map/Greenplum

 

Function

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

Purpose

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

Basic settings

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.

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
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
.

 

Default Table Name

Type in the default table name.

 

Default Schema Name

Type in the default schema name.

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 +
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

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

Note

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