Schema and Edit
schema

A schema is a row description, it defines the nature and number
of fields to be processed. The schema is either built-in or remotely stored in
the Repository. The Schema defined is then passed on to the ELT Mapper to be
included to the Insert SQL statement.

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.

between database and Java. For more information about the metadata mapping,
see the related documentation for Type mapping.

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 rule

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