[teiid-issues] [JBoss JIRA] (TEIID-4573) Modeshape query

[Horia Chiorean (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-4573?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13322415#comment-13322415 ] 

Horia Chiorean commented on TEIID-4573:
---------------------------------------

[~van.halbert]: you are correct, the grammar for {{ComparisonConstraint}} looks like:
{code}
Comparison ::= DynamicOperand Operator StaticOperand
{code}
so in the previous query the right hand side of the {{=}} constraint would not work anyway.

I was referring to the fact that {{DynamicOperand}} for {{PropertyValue}} looks like this:
{code}
PropertyValue ::= [selectorName'.'] propertyName
{code}
and {{propertyName}} conforms to the "generic" Name grammar which is 
{code}
Name ::= '[' quotedName ']' | '[' simpleName ']' | simpleName
{code}

So in the above query, on the left-hand side (assuming the right-hand side was a {{StaticOperand}}), using {{selector."propertyName"}} would not be a valid construct.
