My addition:
Pass a parameter like command=delta-import&idz=31415
And access it via 'sql where id=${dataimporter.request.idz}'
If the idz is a string you might need to prequote the idz value.

Subject: DIH and updating specific record
Hi all-
I am trying to determine if there is a way to tell Solr to update its
index with a specific ID to a record in the database. All the examples
and documentation seems to discuss using a "last updated" date/time
field, but in this case modifying the table would not be an option.
Instead, I'd like to invoke Solr's DIH delta query with a specific ID to
say "here's something new or updated, please update your index with it".
I apologize if this is a trivial thing, but I can't seem to find any
documentation on how to do it.
Thanks,
Ron
