tELTNetezzaOutput – Docs for ESB 6.x

tELTNetezzaOutput

Performs the action (insert, update or delete) on data in the specified Netezza
table through the SQL statement generated by the tELTNetezzaMap
component.

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

tELTNetezzaOutput Standard properties

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

The Standard
tELTNetezzaOutput component belongs to the ELT family.

The component in this framework is generally available.

Basic settings

Action on data

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

Insert: Adds new entries to the table.

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, it defines the number of fields
that will be processed and passed on to the next component.

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.

Click Sync columns to
retrieve the schema from the previous component connected in the Job.

 

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.

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 define a different output table name,
between double quotation marks, in the Table
name
field that appears.

Mapping

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.

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

Usage rule

tELTNetezzaOutput is to be used along
with the tELTNetezzaMap. 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.
