Add public getter for FbCommand._namedParameters

[dant02]

Hi,

would it be feasible to add public getter to _namedParameters field in FbCommand ?

My use case is to get names of the parameters for a query which I do not know beforehand.

I'll be happy to create PR for it.

Thank you Best regards Daniel Trubač

Yeah. I don't see a reason why not. So go ahead with your PR.
