SQL Server: Index local temp tables

[detule]

Fixes #584

With this, dbExistsTable( conn, "#tempname") should be reliable. In turn writing to local temp tables with dbWriteTable or dbAppendTable should also be improved.

I am tracking additional issues with temp tables in SQL Server. Will address separately.

As I was working on this I was reminded that we need to add a DB/workflow using FreeTDS to CI/CD ( mostly a note to myself ).

Thanks!

I'd suggest just writing all these method docs in a bulleted list in the SQLServer docs. That makes it a bit easier to see how the final rendered doc will look.

And I think it's fine to leave the @usage as is, so the read can more easily see what methods are customised.

Thanks Hadley.

I took a look at the markdown in SQLServer.md and fwict it already looks like a bulleted list:

  \details{
  True if:
  \itemize{
  \item If catalog_name is supplied it must equal "temdb" or "\%" ( wildcard )
  \item Name must start with "#" followd by a non-"#" character
  }

Let me know if you had something else in mind.

RE: usage, I spend some time struggling with this:

❯ checking for code/documentation mismatches ... WARNING
  Functions or methods with usage in documentation object 'Microsoft SQL Server-class' but not in code:
    ‘\S4method{isTempTable}{Microsoft SQL Server,character}’

My first thought was that it has something to do with the class name having white-space characters but now i am not so sure.

The class and method are tagged like so:

  \name{Microsoft SQL Server-class}                                                                                                                                                                                                         
  \alias{Microsoft SQL Server-class}
  \alias{isTempTable,Microsoft SQL Server,character-method}

while the usage section:

\usage{
  \S4method{isTempTable}{`Microsoft SQL Server`,character}(conn, name, catalog_name = NULL, schema_name = NULL, ...)                                                                     
}

Let me know if you have any ideas.

Thanks again!

If you manually change the alias to the following, does the problem go away?

  \alias{isTempTable,`Microsoft SQL Server`,character-method}

Good suggestion; alas doesn't work.

Weird! Definitely not worth looking into further.
