miguelpragier opened a new issue, #39238:
URL: https://github.com/apache/arrow/issues/39238
### Describe the bug, including details regarding any error messages,
version, and platform.
# Description
When having an empty resultset, the driver tries to include an empty record
referece, that cannot be scanned.
So, any operation that relies on the returned ***Rows** will trigger a
_"Index out of Range"_ error.
### We wrote a patch that prevents empty records to be appended to the
resultset.
### Further Details
The error is detected here, when r.currentRecord is mistankely 1, when
should be zero:
At: `/flight/flightsql/driver/driver.go:87`
```golang
func (r *Rows) Next(dest []driver.Value) error {
if r.currentRecord >= len(r.records) {
return io.EOF
}
record := r.records[r.currentRecord]
if int64(r.currentRow) >= record.NumRows() { // IS TRIGGERED HERE
return ErrOutOfRange
}
```
But happens here:
At: `/flight/flightsql/driver/driver.go:492`
```golang
for reader.Next() {
record := reader.Record()
record.Retain()
records = append(records, record) // BUT HAPPENS HERE
}
```
### Platform, Arrow/Flight & Go
OS: Linux
Arrow Driver: github.com/apache/arrow/go/v14/arrow/flight/flightsql/driver
Go Version: go1.21.4 linux/amd64
### Component(s)
