tMSSqlBulkExec – Docs for ESB 6.x

tMSSqlBulkExec

Offers gains in performance while executing the Insert operations to a Microsoft
SQL Server database.

The tMSSqlOutputBulk and tMSSqlBulkExec components are used together in a two step
process. In the first step, an output file is generated. In the second step, this file
is used in the INSERT operation used to feed a database. These two steps are fused
together in the tMSSqlOutputBulkExec component,
detailed in a separate section. The advantage of using a two step process is that the
data can be transformed before it is loaded in the database.

tMSSqlBulkExec Standard properties

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

The Standard
tMSSqlBulkExec component belongs to the Databases family.

The component in this framework is generally available.

Basic settings

Property type

Either Built-in or Repository
.

 

Built-in: No property data is stored
centrally.

 

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

JDBC Provider

Select the provider of the JDBC driver to be used, either Microsoft (recommended) or Open
source JTDS
.

When using this component with Datasource in Talend Runtime, you need
to use the Open source JTDS driver.

Note that when Microsoft is selected, you
need to download the Microsoft JDBC Driver for SQL Server on Microsoft Download Center, unpack
the downloaded zip file, choose a jar in the unzipped folder based on your JRE version,
rename the jar to mssql-jdbc.jar and install it manually. For more
information about choosing the jar, see the System Requirements information on Microsoft Download Center.

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

Database server IP address

Port

Listening port number of DB server.

Database

Name of the database.

Schema

Name of the schema.

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.

Table

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: 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 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.

Truncate table: The table content is
deleted. You do not have the possibility to rollback the
operation.

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. 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. 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.

You can find more details about how to verify default
values in retrieved schema in Talend Help Center (https://help.talend.com).

 

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.

Remote File Name

Name of the file to be loaded.

Warning:

This file is located on the machine specified by the URI in the
Host field so it should be on
the same machine as the database server.

Advanced settings

Action

Select the action to be carried out

Bulk insert
Bulk
update Bcp query out
Depending on the action selected,
the requied information varies.

Usage

Usage rule

This component is to be used along with tMSSqlOutputBulk component. Used together, they can
offer gains in performance while feeding a MSSql database.

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 Scenario: Reading data from databases through context-based dynamic connections and Scenario: 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

Due to license incompatibility, one or more JARs required to use this component are not
provided. You can install the missing JARs for this particular component by clicking the
Install button on the Component tab view. You can also find out and add all missing JARs easily on the
Modules tab in the
Integration
perspective of your
studio. You can find more details about how to install external modules in Talend Help Center (https://help.talend.com).
