|
tTeradataFastLoad reads a
database and extracts fields using queries.
|
|
Purpose

tTeradataFastLoad executes a
database query according to a strict order which must be the same as
the one in the schema. The retrieve list of fields is then
transfered to the next component, using a connection flow (Main row).
|
|

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.
|
|
|
|
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.

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.
