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 connection or fetch a connection shared by a parent or child Job. This allows you to share one single database connection among several database connection components from different Job levels that can be either parent or child.

Note that 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. For a related use case, see Deploying your Job on Talend Runtime to retrieve data from a MySQL database.

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.
