its task.

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

If this component is linked to your Job via a Row > Main connection, 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 the first row commit.

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at the Job level
as well as at each component level.

ERROR_MESSAGE

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 more commonly used with other tJDBC*
components, especially with the tJDBCConnection and tJDBCRollback 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.

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.
