tSQLDWHConnection – Docs for ESB 7.x

tSQLDWHConnection

Opens a connection to an Azure SQL Data Warehouse database.

tSQLDWHConnection Standard properties

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

The Standard
tSQLDWHConnection component belongs to two families:
Cloud and Databases.

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

Basic settings

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.

JDBC Provider

Select the provider of the JDBC driver to be used.

Host

Specify the IP address or hostname of the Azure SQL Data Warehouse to be used.

Port

Specify the listening port number of the Azure SQL Data Warehouse to be used.

Schema

Enter the name of the Azure SQL Data Warehouse schema.

Database

Specify the name of the Azure SQL Data Warehouse to be used.

Username and Password

Enter the user authentication data to access the Azure SQL Data Warehouse.

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.

Additional JDBC Parameters

Specify additional connection properties for the database
connection you are creating. The properties are separated by semicolon and
each property is a key-value pair. For example, encrypt=true;trustServerCertificate=false;
hostNameInCertificate=*.database.windows.net;loginTimeout=30; for
Azure SQL database connection.

Use or register a shared DB Connection

Select this check box to share your
database connection or fetch a database connection shared by a parent or child Job,
and in the Shared DB Connection Name field displayed, enter the
name for the shared database connection. This allows you to share one single database
connection (except the database schema setting) among several database connection
components from different Job levels that can be either parent or child.

This option is
incompatible with the Use dynamic job and Use an
independent process to run subjob
options of the
tRunJob component. Using a shared connection together with a
tRunJob component with either of these two options enabled
will cause your Job to fail.

This check box is not available when the Specify a data source
alias
check box is selected.

Specify a data source alias

Select this check box and in the
Data source alias field displayed, specify the alias of
a data source created on Talend Runtime side to use
the shared connection pool defined in the data source configuration. This option
works only when you deploy and run your Job in Talend Runtime.

This check box is not available when the Use or register a shared DB
Connection
check box is selected.

Advanced settings

Auto Commit

Select this check box to commit any changes to the database
automatically upon the transaction.

With this check box selected, you cannot use the corresponding
commit component to commit changes to the database; likewise, when using the
corresponding commit component, this check box has to be cleared. By
default, the auto commit function is disabled and changes must be committed
explicitly using the corresponding commit component.

Note that the auto commit function commits each SQL statement as a
single transaction immediately after the statement is executed while the
commit component does not commit only until all of the statements are
executed. For this reason, if you need more room to manage your transactions
in a Job, it is recommended to use the commit component.

Share identity insert in multi table

Select this check box to share IDENTITY_INSERT with multiple tables in one
connection.

tStatCatcher Statistics

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

Global Variables

ERROR_MESSAGE

The error message generated by the component when an error occurs. This is an After
variable and it returns a string.

Usage

Usage rule

This component is more commonly used with other Azure SQL Data Warehouse components
and it opens a connection that can be reused by them.

Limitation

Note that some features that are supported by
other databases are not supported by Azure SQL Data Warehouse. For more information,
see Unsupported table features.
