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.
|
|
|
|
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.

Advanced settings

tStatCatcher Statistics
|
Select this check box to collect log data at the component
level.
|
|
Dynamic settings
|
Click the [+] button to add a row in the table and fill
the Code field with a context variable to choose your
database connection dynamically from multiple connections planned in your Job. This feature
is useful when you need to access database tables having the same data structure but in
different databases, especially when you are working in an environment where you cannot
change your Job settings, for example, when your Job has to be deployed and executed
independent of Talend Studio.
Once a dynamic parameter is defined, the Component List
box in the Basic settings view becomes unusable.
For more information on Dynamic settings and context
variables, see Talend Studio User Guide.

|
Global Variables
|
NB_LINE: the number of rows processed. 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.
