The document discusses how to extract workflow status and name from the PSR table in a database. It explains that workflow statuses are node types stored in the NODETABLE, not list values. It provides an SQL query to join the PSR, NODETABLE, and NODETABLE tables to retrieve the PSR number, workflow name from NODETABLE.flow.description, and workflow status from NODETABLE.state.description.

1. Trying to find the workflow
status in the database?
Hint - Workflow status' aren't list
values...

2. Introduction
Our help desk recently fielded a support ticket
from a company looking for assistance with their
extraction of PSR content. Specifically, they
could not identify how to extract the PSR
number, the workflow name and workflow
state. One can be very quick to jump to the
conclusion that workflow states are list items
and should reside in the LISTENTRY table, but
that is not the case.

3. Examine PSR Table
Let's examine a simple result set with the PSR number,
workflow and workflow state by executing:
select psr_no, workflow_id, status from psr;
As you can see, we have an empty PSR record, which is easy
to filter out by adding a where clause to our query. The
harder thing to figure out is where to find the human
readable versions of workflow_id and status.

4. Looking to NODETABLE for Help
If you think about the Java Client, you'll realize that a
workflow state is actually a type (or node), not a simple
list value. These exist in NODETABLE, so we can add
some joins and pull in the appropriate values:
select psr_no as psr, flow.description as workflow, state.description as state
from psr
left join nodetable state on (state.id=psr.status)
left join nodetable flow on (flow.id=psr.workflow_id)
where psr_no is not null;

5. Looking to NODETABLE for Help (cont)
Now we can see that the values are being pulled out
correctly.
