spec_arrow_fetch_arrow_chunk
Description
spec_arrow_fetch_arrow_chunk
Value
dbFetchArrowChunk() always returns an object coercible to a 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.
Failure modes
An attempt to fetch from a closed result set raises an error.
Specification
Fetching multi-row queries with one
or more columns returns the next chunk.
The size of the chunk is implementation-specific.
The object returned by dbFetchArrowChunk() can also be passed to
nanoarrow::as_nanoarrow_array() to create a nanoarrow array object.
The chunk size is implementation-specific.
