Action on data

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

Insert: Add new entries to the table. If
duplicates are found, Job stops.

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
to be processed and passed on to the next component. The schema is either
built-in or remotely stored in the Repository.

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.

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 inverted commas.

Note that the table must exist already. If it
does not exist, you can use tCreateTable to create one
first. For more information about tCreateTable, see tCreateTable.

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 which 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.

tStatCatcher Statistics

Select this check box to collect log data at the component level.

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.
