CMIS Query to get documents with a specific aspect property value

The query errors out stating the below issue. Please can you let me know what is wrong with the query.Error Content:{"exception":"in

Try the following sentence:

SELECT * FROM td:defaultAspect WHERE td:docStatus ='Active' and CONTAINS('PATH:\"/app:company_home/st:sites/cm:testsite/cm:documentLibrary//*\"')‍

I believe you cannot select only on an aspect. You have to use a CMIS base type, even if that is just cmis:item, and then join with the aspect..

Here is how you do a join so that you can query aspect-based properties while simultaneously restricted the results to those in a certain path:

select D.cmis:name from cmis:document as D join sc:temp as T on D.cmisbjectId = T.cmisbjectId where T.scrop1 = 'value1' AND CONTAINS(D, 'PATH:\"/app:company_home/st:sites/cm:jtp-test-site-1/cm:documentLibrary//*\"')

The missing tidbit is that because you are doing a join, the selector ("D") has to be specified in the CONTAINS.

Axel, this query is working:

SELECT * FROM cm:titled

I've been writing queries by using only aspects many times. Am I wrong or I missed something?

As discussed in the IRC channel, the spec explicitlely states that only primary object types are supported in the FROM clause, but Alfresco has implemented it in a way that aspects / secondary object types can also be used. The reason for this is that the text of the spec was not fully consistent with the BNF of the query language, and Alfresco apparently followed the text more closely than the formal definition.

I believe you got ample answers. I do like below, in case it helps in any way

SELECT doc.*, slo.* FROM cmis:document AS doc JOIN slo:documentProperties AS slo ON doc.cmisbjectId = slo.cmisbjectId WHERE IN_FOLDER(doc, 'workspace://SpacesStore/3105f215-228e-4087-aef8-4a9399eb0b60') AND (slo.slo:m_link = 128) AND (slo.slo:m_category = 'Person')

m_link and m_category are the aspect properties

I have an aspect defined this way in our own custom model. Here is an extract of our custom model.

<types>

<type name="slo:mdocument">
<title>SLO Document type</title>
<parent>cm:content</parent>



<mandatory-aspects>
<aspect>slo:documentProperties</aspect>
</mandatory-aspects>
</type>

</types>

<aspects>

<aspect name="slo:documentProperties">
<title>m document properties</title>
<properties>

<property name="slo:m_category">
<title>Category</title>
<type>d:text</type>

</property>
<property name="slo:m_link">
<title>Link ID</title>
<type>d:int</type>
</property>
