I have a table similar to this:
id name added count flag
---------------------------------
01 abcd1 09.02.13 4 false
02 abcd1 10.02.13 1 true
03 abcd1 11.02.13 3 false
04 abcd1 12.02.13 4 false
I need to find sum of count for a given name with the following conditions:
- For a given name
- Flag should be false
- Entry should be added after the last flag=true entry for that name
In this case I want sum of count for entries 03 and 04.
How should I do this in Django?
EDIT:
I am looking for creating a query like this:
SELECT id from sample
WHERE
name = 'abcd1' AND
added > (SELECT MAX(added) FROM sample WHERE name = 'abcd1' AND flag = TRUE)
EDIT: Also if there was no entry with flag=true then I need all the entries for that name.
