Query with parameter inside square brackets

[Riccardo Tasso]

Hi,

   I have a query similar to the following in Orient 2.0.12:

SELECT out()[group=:group]
FROM Person

I execute it from Java, with the following method over ODatabaseDocumentTx:

db.query(query, paramsMap);

It seems that parameters can't be used inside square brackets, as you can see also in the attached UnitTest.

I think this is a bug, can you fix it in 2.0.13 release?

Otherwise can you help me obtaining the same results without this syntax?

Cheers,

   Riccardo

@Richard: Just for my education, what does this syntax do?

:group declares a named parameter that allows the caller to pass a value into the query thus making the query dynamic rather than hard coding.

and out()[group = :group] applies a filter on the out() such that only those vertices which contain group property = the passed value are returned

hope that helps

Ah ha! Thanks!
