update queries - Allow set the value of one translated property.

[rfanjul]

Having the next Document and values.

I am trying to create/update a new property "extid". Tested two queries which the first one , with success result is:
UPDATE nt:unstructured as a SET a.extid='1' WHERE phpcr:class="Joiz\CmsBundle\Document\ShowInstance";

However i am not be able to set the value of the property phpcr_locale:en-extid in the following second query:

UPDATE nt:unstructured as a SET a.extid=a.[phpcr_locale:en-extid] WHERE phpcr:class="Joiz\CmsBundle\Document\ShowInstance"; `

The error I got is:

[PHPCR\ValueFormatException] Invalid value for property "extid": Object values must implement PHPCR\NodeInterface, PHPCR\PropertyInterface or be \DateTime, supplied argument is of class: PHPCR\Shell\Query\ColumnOperand

@dantleech we also tried with
UPDATE nt:unstructured SET extid=[phpcr_locale:en-extid] WHERE phpcr:class="Joiz\CmsBundle\Document\ShowInstance" as the example on http://phpcr.readthedocs.io/en/latest/phpcr-shell/querying.html#updating looks like the name of the document is not used in the update. but still the same error.

You can't use dynamic properties in an update at the moment.

But I think you can use the expr() funtion as follows to achieve what you want I think:

UPDATE nt:unstructured SET extid=expr("row.node.property('phpcr_locale:en-extid')") WHERE phpcr:class="Joiz\CmsBundle\Document\ShowInstance"

Thanks for looking at it. @rfanjul does the expr work for you?

What do you mean with dynamic properties @dantleech ? That setting a property to the value of another property is not implemented? ah, i think i misread the join example... should we add a note about this in the doc? its something people are used to from SQL, so making it explicit this is not yet supported and point to the expr would help.

[dantleech]

it is something we could support. but indeed we could add a note in the docs now and explain that expr() can be used as a workaround.
