Function

The tAccessOutputBulkExec
component executes an Insert action on the data provided.

Purpose

As a dedicated component, it improves performance during Insert
operations in an Access database.

Basic settings

Property type

Repository.

Since version 5.6, both the Built-In mode and the Repository mode are
available in any of the Talend solutions.

Built-in: No property data stored
centrally.

Repository: Select the repository
file in which the properties are stored. The fields that follow are
completed automatically using the data retrieved.

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.

DB Version

Select the version of Access that you are using.

DB name

Name of the database

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.

Action on table

On the table defined, you can perform one of the following
operations:

None: No operation is carried
out.

Drop and create table: The table is
removed and created again.

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

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

Drop table if exists and create:
The table is removed if it already exists and created again.

Clear table: The table content is
deleted.

Related topic: see Talend Studio User Guide.

Action on data

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

Insert: Add new entries to the
table.

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
stored remotely in the Repository.

Since version 5.6, both the Built-In mode and the Repository mode are
available in any of the Talend solutions.

Built-In: You create and store the schema locally for this
component only. Related topic: see Talend Studio
User Guide.

Repository: You have already created the schema and
stored it in the Repository. You can reuse it in various projects and Job designs. Related
topic: see Talend Studio User Guide.

When the schema to be reused has default values that are integers or functions, ensure that
these default values are not enclosed within quotation marks. If they are, you must remove
the quotation marks manually.

For more details, see https://help.talend.com/display/KB/Verifying+default+values+in+a+retrieved+schema.

Click Edit schema to make changes to the schema. If the
current schema is of the Repository type, three options are
available:

Create directory if not exists

Select this check box to create the as yet non existant file
directory specified in the File
name field.

Append

Select this check box to append new rows to the end of the
file.

Advanced settings

Additional JDBC parameters

Specify additional connection properties for the DB connection you
are creating. This option is not available if you have selected the
Use an existing connection
check box in the Basic
settings.

Include header

Select this check box to include the column header to the file.

Encoding

Select the encoding from the list or select Custom and define it manually. This field is
compulsory for DB data handling.

tStatCatcher Statistics

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

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 more information on Dynamic settings and context
variables, see Talend Studio User Guide.

Usage

This component is mainly used when no particular transformation is
required on the data to be loaded in the database.

Limitation

If you are using the 64-bit version of the Studio, you should use
the 32-bit versions of the ODBC driver and of the Java
environment.
