Ok, I think the problem comes from raw text, it does not appear ...
```
self.client = Client()
self.client.connect('127.0.0.1', 10800)
patientID = 5
IS_DEFINED_QUERY = "SELECT * FROM Patients WHERE PatientID = ?"
result = self.client.sql(
IS_DEFINED_QUERY,
query_args=[patientID]
)
try:
next(result)
DELETE_QUERY = "DELETE FROM Patients WHERE PatientID = ?"
self.client.sql(
DELETE_QUERY,
query_args=[patientID])
except StopIteration:
raise KeyDoesNotExist()
```
