The option to create maps for the Parameterized Query and Query (non parameterized) columns is available till Denodo 7.0 under the New Source option of the Job Extraction section .
Starting from Denodo 8.0, you can no longer create mappings between columns. Instead of creating mappings, you can alias the variable in your **Parameterized query** to have the same name as the column in the **Query (non parameterized)**.
From above example, if I have configured the Parameterized query with interpolation variables like "@inp_column" and "@description",
ALTER VIEW <View_Name>(
ALTER COLUMN @inp_column ADD ( DESCRIPTION = ‘@description’ )
then I would format my Query (non parameterized) as something like the following:
`select <column_name> as inp_column, <column_description> as description from <base_view_over_excel>`
By doing so, the columns will be automatically mapped to each other.
For more information, refer to the latest [VDP Extraction Section](https://community.denodo.com/docs/html/browse/latest/en/scheduler/administration/creating_and_scheduling_jobs/configuring_new_jobs/vdp_extraction_section#vdp-extraction-section) of the Scheduler Administration Guide.
Hope this helps!
