Here’s the workflow flow I’m using. <atomic-commit> <dataset name=foo/> </atomic-commit> <dataset-iterator dataset=foo> <create-row dataset=hist-foo/>

Here’s the workflow flow I’m using.

<atomic-commit>
   <dataset name="foo"/>
</atomic-commit>

<dataset-iterator dataset="foo">
    <create-row dataset="hist-foo"/>
    <mark-row-created dataset="hist-foo"/>
</dataset-iterator>

So basically, after dataset foo is updated, I want to record the remaining foo entries in another history table. But when I delete rows from the foo table, the rows still remain in the dataset and therefore get added to hist-foo.
I’ve tried to add a post-workflow to the foo databroker’s delete action like this:

<workflow>
     <delete-row dataset="{$context.commit-dataset-name}"/>
</workflow>

However I get an error when the delete action is called.

Also, after the first atomic commit, the foo dataset doesn’t keep deleted row actions, so I can’t identify which rows from deleted from the dataset.

    The simplest solution for this situation would be to sift the marked-deleted rows into a separate dataset. Unfortunately this is a little long when using only built-in commands.

    <dataset name="deleted-foo" databroker="..."/>

<dataset-iterator dataset="foo">
    <if test="row-marked-deleted" value1="foo">
        <then>
            <create-row dataset="deleted-foo"/>
            <copy-row from-dataset="foo" to-dataset="deleted-foo"/>
            <mark-row-deleted dataset="deleted-foo"/>
        </then>
    </if>
</dataset-iterator>

<!-- Keeping in mind that you can't delete rows from a dataset
     which is being iterated over. -->
<dataset-iterator dataset="deleted-foo">
    <dataset-reset dataset="foo" no-current-row="y"/>
    <!-- Assuming rows have a field 'id' which uniquely IDs them -->
    <set-current-row-by-field dataset="foo" field="id" value="{$deleted-foo.id}"/>

    <if test="dataset-has-current-row" value1="foo">
        <then>
            <delete-row dataset="foo"/>
        </then>
    </if>
</dataset-iterator>

<atomic-commit>
    <dataset name="deleted-foo"/>
    <dataset name="foo"/>
</atomic-commit>

<dataset-iterator dataset="foo"> 
    <create-row dataset="hist-foo"/> 
    <mark-row-created dataset="hist-foo"/> 
</dataset-iterator>

    An alternate solution would be to do the history recording at the same time as the inserts/updates were run, for example by running multiple statements within the operations or by having insert/update triggers set up if those are available.
