>                 URL: https://issues.apache.org/jira/browse/CALCITE-1191
>             Project: Calcite
>          Issue Type: Improvement
>          Components: avatica
>    Affects Versions: avatica-1.7.1
>            Reporter: Francis Chuang
>
> I am currently working on a golang sql driver for avatica. There are a few 
> implementable interfaces that allows short cutting by preparing and executing 
> a statement in one request.
> For example, the Execer interface: 
> https://golang.org/pkg/database/sql/driver/#Execer
> Currently, I am unable to use PrepareAndExecute to implement this short-cut 
> as it doesn't accept any bound parameters.
> It would be extremely useful if PrepareAndExecute supports bound parameters 
> so that we don't have to make multiple trips to the server.
