I am new to Django and I am enjoying it. I ran into an issue while
creating a SQL query for my project. I want the following query to run
using Django
Query:
Select id,field1,field2,field3 FROM table WHERE field1 = somevalue
Group by concat(field1,field2) ORDER BY somefield
However I am not able to get the desired query. It keeps on adding group
by id which is not what I want.
Django query:
result = query.annotate(person=Concat(F('field1'),
F('field2'))).annotate(Count('person', distinct=True))
Outputs:
SELECT id FROM table WHERE my condition GROUP BY id ORDER BY field
Please let me know if you have any questions.
