Select a type of database from the list and click
Apply.

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

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.

Host

Database server IP address.

Port

DB server listening port.

Database

Name of the database.

Schema

Name of the schema.

Username and
Password

User authentication information.

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.

Instance

Name of the Informix instance to be used. This information can
generally be found in the SQL hosts file.

Table

Name of the table to be created

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. When you create a Spark
Job, avoid the reserved word line when naming the
fields.

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 improve system performance.

Source keys include Null

Select this check box to allow the source key columns to have Null
values.

Use Transaction

Select this check box when the database is configured in NO_LOG
mode.

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.

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 of the process by which
data is written in the database.

tStatCatcher Statistics

Select this check box to collect the log data at a 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 an output component. Consequently, it
requires an input component and a connection of the Row > Main type.

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 Reading data from databases through context-based dynamic connections and 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.

Limitation

This component does not support using SCD type 0 together with other
SCD types.
