Use an existing connection

Select this check box and in the Component
List click the relevant connection component to reuse the connection
details you already defined.

Property type

Either Built-in or Repository.

Built-in: No property data stored
centrally.

Repository: Select the Repository
file where properties are stored. The following fields are
pre-filled in using fetched data.

Host

Database server IP address.

Port

Listening port number of DB server.

Database

Name of the database.

Table Schema

Name of the DB schema.

Username and
Password

DB user authentication data.

To enter the password, click the […] button next to the
password field, and then in the pop-up dialog box enter the password between double quotes
and click OK to save the settings.

Table

Name of the table to be written. Note that only one table can be
written at a time.

Schema and Edit
schema

A schema is a row description. It defines the number of fields (columns) to
be processed and passed on to the next component. The schema is either Built-In or stored remotely 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.

SCD Editor

The SCD editor helps to build and configure the data flow for
slowly changing dimension outputs.

For more information, see SCD management methodology.

Use memory saving Mode

Select this check box to maximize system performance.

Die on error

This check box is cleared by default, meaning to skip the row on
error and to complete the process for error-free rows.

Additional JDBC parameters

Specify additional connection properties for the DB connection you
are creating.

End date time details

Specify the time value of the SCD end date time setting in the
format of HH:mm:ss. The default
value for this field is 12:00:00.

This field appears only when SCD Type 2 is used and
Fixed year value is selected for creating the SCD
end date.

Debug mode

Select this check box to display each step during processing
entries in a database.

tStatCatcher Statistics

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

Global Variables

NB_LINE_UPDATED: the number of rows updated. 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.

NB_LINE_REJECTED: the number of rows rejected. 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 rule

This component is used as Output component. It requires an Input
component and Row main link as input.

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
.

The Dynamic settings table is
available only when the Use an existing
connection check box is selected in the Basic settings view. Once a dynamic parameter is
defined, the Component List box in the
Basic settings view becomes unusable.

For examples on using dynamic parameters, see Scenario: Reading data from databases through context-based dynamic connections and Scenario: Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic
settings and context variables, see
Talend Studio User Guide.

This component requires installation of its related jar files.

Note that the DB2 10.5 driver doesn’t support JDK 8. To use this component with DB2 10.5,
you need to install JDK 7 or an earlier version.
