Does your library have functions for reading columns directly from the sql results into elisp?

emacs-sqlite3-api has the sqlite3-column-* functions for retrieving the results of a row.

Does your package have functions which can be used in this manner?

edbi just has edbi:fetch-d (retrieving rows) and edbi:fetch-columns-d (retrieving column names of result set). Example: https://github.com/kiwanami/emacs-edbi/blob/master/examples/api.el

I think this package doesn't support general purpose because of less use cases of database applications in emacs.
