tMysqlCommit

Commits in one go, using a unique connection, a global transaction instead of doing
that on every row or every batch and thus provides gain in performance.

tMysqlCommit validates the data processed through the
Job into the connected DB.

tMysqlCommit Standard properties

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

The Standard
tMysqlCommit component belongs to the Databases family.

The component in this framework is generally available.

Basic settings

Component list	Select the tMysqlConnection 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 commit is done. Clear this check box to continue to use the selected connection once the component has performed its task. Warning: If you want to use a Row > Main connection to link tMysqlCommit to your Job, your data will be committed row by row. In this case, do not select the Close connection check box or your connection will be closed before the end of your first row commit.

Component list

Select the tMysqlConnection
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 commit is done. Clear this check box to
continue to use the selected connection once the component has
performed its task.

Warning:

If you want to use a Row
>

Main
connection to link tMysqlCommit to your Job, your data will be
committed row by row. In this case, do not select the
Close connection check
box or your connection will be closed before the end of your
first row commit.

Advanced settings

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

Global Variables

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. This variable functions only if the Die on error check box is cleared, if the component has this check box. A Flow variable functions during the execution of a component while an After variable functions after the execution of the component. To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it. For further information about variables, see Talend Studio User Guide.

Usage

Usage rule	This component is more commonly used with other tMysql* components, especially with the tMysqlConnection and tMysqlRollback 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 Scenario: Reading data from databases through context-based dynamic connections and Scenario: 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.
