tSnowflakeRollback Standard properties

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

The Standard tSnowflakeRollback component belongs to the Cloud family.

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

Information noteNote: This component is a specific version of a dynamic database connector. The properties related to database settings vary depending on your database type selection. For more information about dynamic database connectors, see Dynamic database components.

Basic settings


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

Connection Component

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

Close Connection

Clear this check box to continue to close the selected connection once the component has performed its task.

Advanced settings

tStatCatcher Statistics

Select this check box to collect log data at the component level.

Global variables


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


Usage rule

This component is designed to work with tSnowflakeRow, tSnowflakeBulkExec, and tSnowflakeOutputBulkExec components.

When this component works with a tSnowflakeRow component with no input or output row, changes made to the database are rolled back by the tSnowflakeRollback component.

When this component works with a tSnowflakeRow component with an input row, the tSnowflakeRollback component takes the charge of rolling back changes made to the database if the Commit every option of the tSnowflakeRow component is set to 0 or 1; the tSnowflakeRollback component will be ignored if the value of the Commit every option of the tSnowflakeRow component is larger than 1.

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.
