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

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

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

Basic settings

Component List

Select the tSQLDWHConnection component in the list if more than one connection are planned for the current Job.

Close Connection

This check box is selected by default. It allows you to close the database connection once the operation is done. Clear this check box to continue to use the selected connection once the component has performed its task.

Advanced settings

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, especially with the tSQLDWHConnection and tSQLDWHCommit components.

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 .

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.

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.
