Cool. But as Stefan and Mike also mentioned there is no ultimate need to use Query Database node for your use case.

This solved the initial problem

And as I discussed in at least one other thread already with this user, there's no need to use the Query Database node in this manner at all. Query Record or Query Entity should be being called in a Script Task (or, as you suggest, on the start form) and saving their output into the process.

On the form, collect the records to be deleted. Pass these to the process and use the deleteRecords node to delete them.

Solution to original question:

Select below highlighted option on the assignment tab

I'm talking about the Form that you may have configured in the Query Database node as you are providing assignment for this node.

I need to:
A) select X items from a read only grid
B) pass those values to the process model
C) delete selected items

I don't see how the system would have gotten to the "Script Task" had I not clicked the button for submit it.

OK. Then this node has failed. Please check the tomcat-stdout log file for any details.

Is there a specific reason to not use Appian's normal way of accessing the database?

I think the longer time is due to the assignment, the node will not stop executing until the form has been submitted.

I would like to query the database and store the results in a list/array of records.
My first step was to see if I could query the database.
The initial process that I started a few days ago is still actually running

I'm not getting any errors, the node does have an assigned user.

Me neither. What is the deal with the assignment? What are you looking for?

Umm, so this is the assignment

I'm not too sure how your previous comment helps solve the issue

There is a common misconception about Appian process performance. This is mixing up low level code execution time vs. node duration time. Appian is made to scale horizontally and can run millions of process instances at the same time. An individual process or node will not be run any faster.

Keep in mind, this is about implementing a business process and assigning tasks to people. People do not know that they will get a task assigned, so they do not wait for it.
