'Sum' aggregate function not working with Window function for sqlite3
version 3.27.2
Produces these errors:
>>>sqlite3.OperationalError: near "OVER": syntax error
>>>django.db.utils.OperationalError: near "OVER": syntax error
This is similar to the fixed issue #30027 "SQLite (pre 3.25.0) does not
support window functions, raises OperationalError", but I am using SQLite
3.27.2 and the native SQL query is working from sqlite3 command line and
also when using Model.objects.raw(), which I'm having to use as a
workaround.
It should be reproducible as follows, assuming model "myapp.mymodel" has a
field "amount":
>>>from django.db.models import Sum, Window
>>>from myapp.models import mymodel
>>>mymodel.objects.all().annotate(cumsum=Window(expression=Sum('amount')))
The raw query works OK:
>>>rawqs=mymodel.objects.raw("SELECT *, SUM (amount) OVER (ORDER BY id) AS
cumsum FROM myapp_mymodel")
