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

Execution platform

operations:

None: No operation is carried
out.

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

Create a table: The table does not

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

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:

Informix Directory

Informix installation directory, e.g. ”
C:Program FilesIBMIBM Informix Dynamic
Server11.50″.

Data file

Name of the file to be generated and loaded.

Append

Select this check box to add rows to the end of the file.

Action on data

Select the operation you want to perform:

Bulk insert Bulk update The details asked will be different
according to the action chosen.

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.

Row separator

String (ex: ”
“on Unix) to distinguish rows.

Fields terminated by

Character, string or regular expression used to separate the
fields

Set DBMONEY

Select this check box to define the decimal separator used in the
corresponding field.

Set DBDATE

Select the date format you want to apply.

Rows Before Commit

Enter the number of rows to be processed before the commit.

Bad Rows Before Abort

Enter the number of rows in error at which point the Job should
stop.

Create directory if not exists

This check box is selected by default. It creates a directory to
hold the output table if required.

Custom the flush buffer size

Select this box in order to customize the memory size used to
store the data temporarily. In the Row
number field enter the number of rows at which point
the memory should be freed.

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 a component
level.

Output

Where the output should go.

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 generally used when no particular transformation
is required on the data to be inserted in the database.

Limitation

The database server/client must be installed on the same machine
where the Studio is installed or where the Job using tInformixOutputBulkExec is deployed, so
that the component functions properly.
