Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Specifying table selection and transformations rules from the console

You can use the Amazon Web Services Management Console to perform table mapping, including specifying table selection and transformations. On the console, use the Where section to specify the schema, table, and action (include or exclude). Use the Filter section to specify the column name in a table and the conditions that you want to apply to a replication task. Together, these two actions create a selection rule.

You can include transformations in a table mapping after you have specified at least one selection rule. You can use transformations to rename a schema or table, add a prefix or suffix to a schema or table, or remove a table column.


Amazon DMS doesn't support more than one transformation rule per schema level, table level, or column level.

The following procedure shows how to set up selection rules, based on a table called Customers in a schema called EntertainmentAgencySample.

To specify a table selection, filter criteria, and transformations using the console
  1. Sign in to the Amazon Web Services Management Console and open the Amazon DMS console at https://console.amazonaws.cn/dms/v2/.

    If you are signed in as an IAM user, make sure that you have the appropriate permissions to access Amazon DMS. For more information about the permissions required, see IAM permissions needed to use Amazon DMS.

  3. Choose Create Task.

For information about other wildcards you can use, see Wildcards in table mapping. Specify the action to be taken, to include or exclude data defined by the filter.
