-----------------------------------
Summary: Issue with SQLTransform in python 3.7.11
Key: BEAM-12804
URL: https://issues.apache.org/jira/browse/BEAM-12804
Project: Beam
Issue Type: Bug
Components: sdk-py-core
Reporter: sean teeling
Using a SQLTransform results in an error.
python --version
Python 3.7.11
pip list | grep apache-beam
*apache-beam* 2.31.0
The following code works if removing the SQLTransform:
```
import itertools
import csv
import io
import apache_beam as beam
from apache_beam.dataframe.io import read_csv
from apache_beam.transforms.sql import SqlTransform
def parse_csv(val):
deflower_headers(iterator):
return itertools.chain([next(iterator).lower()], iterator)
return csv.DictReader(lower_headers(io.TextIOWrapper(val.open())))
class BeamTransformBuilder():
defbuild(self, pipeline):
practices = (
pipeline
| beam.io.fileio.MatchFiles("data.csv")
| beam.io.fileio.ReadMatches()
| beam.Reshuffle()
| beam.FlatMap(parse_csv)
| beam.Map(lambda x: beam.Row(id="test-id"))
| SqlTransform("""
SELECT
id
FROM PCOLLECTION""")
)
print("should print stuff")
practices | beam.Map(print)
def main():
builder = BeamTransformBuilder()
with beam.Pipeline('DirectRunner') as p:
builder.build(p)
if __name__ == '__main__':
main()
```
