Description

I think it will be useful to add kwargs or args parameters to callproc method for those backends that support more parameters for callproc method (e.g cx_oracle)

I can not use named parameters for my procedures with django db module. =

PEP 249 says that callproc only accept positional arguments.

That said, since we're just forwarding arguments to the underlying library, this small deviation seems acceptable, with a comment explaining it.

Hi,

I made some notes on the PR. Additionally, documentation needed. I suggested making the feature more general, less Oracle-specific, but even if this path is not taken, the new behavior needs to be documented. Currently, callproc is not documented at all, which is a shame, but forgivable considering that the function is as defined in PEP 249; deviating from the PEP justifies adding explicit documentation, probably in docs/topics/db/sql.txt; whether or not that is done, the addition should be mentioned in the release notes (docs/releases/1.8.txt).

Thanks for your detailed comments. New commit pushed. I also replied your comments on github.

Patch needs improvement: set

Implementation needs a DatabaseFeature (e.g. callproc_supports_kwargs) to explicitly enable support for kparams for a backend. The current patch will pass along kparams to the underlying backend as long as they are provided to callproc, which will raise a confusing exception to the user. It should probably raise django.db.utils.NotSupportedError.

Is this patch still being considered for release?
I have the same use-case as the ticket description(cx_Oracle keywordParameters).
