tMysqlRollback – Docs for ESB 7.x

tMysqlRollback

Cancels the transaction commit in the connected MySQL database to avoid committing
part of a transaction involuntarily.

tMysqlRollback Standard properties

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

The Standard
tMysqlRollback component belongs to the Databases family.

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

Note: 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

Database

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

Component list

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

Close Connection

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

Advanced settings

tStat
Catcher
Statistics

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

Usage

Usage rule

This component is more commonly used with other tMysql*
components, especially with the tMysqlConnection and tMysqlCommit 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.
