\value{
\code{dbFetchArrow()} always returns an object coercible to a \link{data.frame} with
as many rows as records were fetched and as many
columns as fields in the result set,
even if the result is a single value
or has one
or zero rows.
}
\description{
spec_arrow_fetch_arrow
}
\section{Failure modes}{
An attempt to fetch from a closed result set raises an error.
}
\section{Specification}{
Fetching multi-row queries with one
or more columns by default returns the entire result.
The object returned by \code{dbFetchArrow()} can also be passed to
\code{\link[nanoarrow:as_nanoarrow_array_stream]{nanoarrow::as_nanoarrow_array_stream()}} to create a nanoarrow
array stream object that can be used to read the result set
in batches.
The chunk size is implementation-specific.
