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

Property Type

Select the way the connection details
will be set.

• Built-In: The connection details will be set
  locally for this component. You need to specify the values for all
  related connection properties manually.

• Repository: The connection details stored
  centrally in Repository > Metadata will be reused by this component. You need to click
  the […] button next to it and in the pop-up
  Repository Content dialog box, select the
  connection details to be reused, and all related connection
  properties will be automatically filled in.

DB Version

Select the version of the database.

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.

When a Job contains the parent Job and the child Job, if you need to
share an existing connection between the two levels, for example, to share the
connection created by the parent Job with the child Job, you have to:

1. In the parent level, register the database connection to be shared
   in the Basic settings view of the connection
   component which creates that very database connection.

2. In the child level, use a dedicated connection component to read
   that registered database connection.

For an example about how to share a database connection across Job
levels, see

Talend Studio
User Guide.

Host

The IP address or hostname of the database.

Port

The listening port number of the database.

Database

The name of the database.

Schema

The schema of the database.

Username and Password

The database 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

The name of the table into
which data will be written.

Action on table

Select an operation to be performed on the table defined.

• None: No operation is carried out.

• Create table: The table does not exist and
  gets created.

• Create table if does not exist: The table is
  created if it does not exist.

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.

• Built-In: You create and store the schema locally for this component
  only.

• Repository: You have already created the schema and stored it in the
  Repository. You can reuse it in various projects and Job designs.

• 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.

SCD Editor

Click the […] button and in the
SCD component editor dialog box displayed,
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

Select the check box to stop the execution of the Job when an error
occurs.

Clear the check box to skip any rows on error and complete the
process for error-free rows.

When errors are skipped, you can collect the rows on error
using a Row > Reject connection.

Additional JDBC Parameters

Specify additional JDBC parameters for the
database connection created.

This property is not available when the Use an existing connection
check box in the Basic settings view is selected.

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 is 12:00:00.

This property is available only when the SCD Type 2 method is used and
Fixed year value is selected for creating the
SCD Type 2 end date in the SCD editor.

Debug mode

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

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at the Job level
as well as at each component level.

NB_LINE_INSERTED

The number of rows inserted. This is an After variable and it returns an integer.

NB_LINE_UPDATED

The number of rows updated. 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.

Usage rule

This component is usually used as an end component of a Job or
subJob and it always needs an input link.

Talend Studio and the
Vertica database create very fast and affordable data warehouse and data mart applications.
For more information about how to configure
Talend Studio
to connect to Vertica, see Talend and HP Vertica Tips and
Techniques.

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.
