Sum - ParadeDB

The sum aggregation computes the sum of a field.

SELECT pdb.agg('{"sum": {"field": "rating"}}') FROM mock_items
WHERE id @@@ pdb.all();

import { search } from "@paradedb/drizzle-paradedb";

await db
  .select({
    agg: search.agg({ sum: { field: "rating" } }),
  })
  .from(mockItems)
  .where(search.all(mockItems.id));

from paradedb import Agg, All, ParadeDB

MockItem.objects.filter(
    id=ParadeDB(All())
).aggregate(agg=Agg('{"sum": {"field": "rating"}}'))

from sqlalchemy import select
from sqlalchemy.orm import Session
from paradedb.sqlalchemy import facets, pdb, search

stmt = (
    select(pdb.agg(facets.sum(field="rating")))
    .select_from(MockItem)
    .where(search.all(MockItem.id))
)

with Session(engine) as session:
    session.execute(stmt).all()

MockItem.search(:id)
        .match_all
        .facets_agg(agg: ParadeDB::Aggregations.sum(:rating))

await dbContext
    .MockItems.Where(item => EF.Functions.All(item.Id))
    .Select(item => EF.Functions.Agg(new { sum = new { field = "rating" } }))
    .ToListAsync();

Expected Response

       agg

SQL Sum Syntax

SQL’s SUM syntax is supported in beta and is enabled by default. To disable it, run

SET paradedb.enable_aggregate_custom_scan TO off;

The following query is equivalent to the above and is executed in the same way.

SQL

SELECT SUM(rating) FROM mock_items
WHERE id @@@ pdb.all();

By default, SUM ignores null values. Use COALESCE to include them in the final sum:

SQL

SELECT SUM(COALESCE(rating, 0)) FROM mock_items
WHERE id @@@ pdb.all();
