RE: ASSOCIATORS OF queries in CMPI

ExecuteQuery would depend upon whether or not the specified SMI-S provider supports it. For what it's worth, OpenPegasus should support it, but some vendors compile it without ExecuteQuery support, and the xq queries would fail against those providers. In SMI-S land, providers normally just support enumeration operations with filters/keys/qualifiers, with xq queries being very rare. 

Hope this helps,

Thanks for responding. I think I understand how to make something like that work (enumerate associations and enumerate references that is), but is there such a thing outside of microsoft as something like

cimcli xq 'ASSOCIATORS OF PG_RegisteredProfile.InstanceID="SNIA+Server
+1.1.0"'

or more mysterious and relevent to my search are the talks of things like:

SELECT a, b, c FROM ASSOCIATORS OF Class.Instance

Is that sort of thing real? Does anyone use queries like this? Do we normally just use the enumeration operations with filters/keys/qualifiers?
