tSAPHanaBulkExec

Improves performance while carrying out the Insert operations to an SAP HANA
database.

Prerequisite

tSAPHanaBulkExec requires the installation of the Java driver
(ngdbc.jar) to connect to SAP HANA.

tSAPHanaBulkExec Standard Properties

These properties are used to configure tSAPHanaBulkExec running in
the Standard Job framework.

The Standard
tSAPHanaBulkExec component belongs to the Business family.

The component in this framework is available in all Talend
products.

Basic settings

Database

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

Property type Select either of the following:

  • Built-in: No property 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.

Note: 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

Add the database server IP address.
Port

Add the listening port number of DB server.
Schema

Add the table name of the database.
Username and Password

Enter 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

Enter the name of the table to be written. Note that only one table
can be written at a time and that the table must exist for the insert operation to
succeed.
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
  • Create table: The table does not exist
    and gets created.
  • Create table if not exists: The table is
    created if it does not 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. You have the possibility to rollback the operation.
  • Truncate table: The table content is
    deleted. You do not have the possibility to rollback the operation.

Type of table storage

This option is only available if you create (with or without drop)
the database table. This option allows you to define the way the data is stored in the
table. The following types of table storage organization are available:

  • Row: Data is stored in rows. It is
    preferable to use this table type if the majority of table access involves
    selecting a few records, with all attributes selected.: The table is
    removed and created again.

  • Column: Data is stored in columns. It is
    preferable to use this table type if the majority of table access will be
    through a large number of tuples, with only a few selected attributes.

  • History column: Creates a table with a
    particular transaction session type called HISTORY.
    Tables with session type HISTORY: The table is support time travel
    queries. For more information on HISTORY and time travel
    queries, see http://help.sap.com/saphelp_hanaplatform/helpdata/en/20/d56cd075191014b7ea9e4e77477aae/content.htm.
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.

  • 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.
Edit Schema
Click Edit
schema to make changes to the schema.

Note: If you
make changes, the schema automatically becomes built-in.

  • 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.
CSV file on the SAP HANA host

Specify the name of the CSV file on the SAP HANA host.
Lines terminated by

Specify the character or sequence of characters used to separate

Specify the character, string or regular expression to separate
fields.

Specify additional JDBC parameters for the
database connection created.
Error log file name

Enter the file path of the log file.
Number of rows to skip Define the specific number of rows in the import file to skip.
Date format Enter the format of the date strings that are encoded in the import data. You can
enter the following values:

  • Y: year
  • MM: month
  • MON: name of the month
  • DD: day
Time format Enter the format of the timestamp strings that are encoded in the import

Usage

Usage rule

Use this component to increase the performance of loading data to an SAP HANA
database.

Support

tSAPHanaBulkExec should be used to interact with the ERP part of
SAP, including S4/HANA.

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.
