Get vertex by class about orientdb-gremlin HOT 5 OPEN

Sorry for the late reply, I'm only just back from holidays.

You can configure this behaviour (prefixing V_ and E_) on OrientGraphFactory.setLabelAsClassName(boolean)

Are you using an existing orientdb that was not created with this driver?

from orientdb-gremlin.

No problem, I hope you've had happy holidays.

Yes, I'm using existing DB. I prefer to create a schema by script rather than by code.

Thanks for your help :)

Hi,

Why I have to query like this to get vertices by class?
graph.V.has("@Class","xxx")
graph.V.hasLabel("class:xxx")

not like this? (by greamlin-scala syntax)
graph.V.has("xxx")

Is this difference come from nature of orientDB..?

...anyway, thx to your contributions very much!

from orientdb-gremlin.

has(String) always checks for property values, not class names, this is true for all gremlin variants and databases. not sure if I understood you correctly...?

from orientdb-gremlin.

Oh, sorry.

I mean: hasLabel(string)

And I found it works fine after some test.

Anyway, I queried my class "A" using
g. V. hasLabel("A")

and it seems works below too.
g. V. hasLabel("class:A")

Is there any difference or better way between them?
