Filtering by totalCount about pg-aggregates

[Claire-Couppie]

Thank you, actually your answer already helped me solve my issue !

My mistake was using the foreign key from warehouses to company instead of warehouses table primary key in the filter, when trying to match my case to the solution that was suggested in graphile-contrib/postgraphile-plugin-connection-filter#152.

I used the query:

query MyQuery {
  companies(
    orderBy: WAREHOUSES_COUNT_DESC
    filter: {warehouses: {aggregates: {distinctCount: {companyId: {greaterThan: "1"}}}}}
  ) {
    nodes {
      warehouses {
        totalCount
      }
    }
  }
}

Which returned an empty list (but worked as expected with greaterThan: "0", returning all totalCount values > 0) instead of:

query MyQuery {
  companies(
    filter: {warehouses: {aggregates: {distinctCount: {id: {greaterThan: "1"}}}}}
  ) {
    nodes {
      warehouses {
        totalCount
      }
    }
  }
}

I'm closing the issue then, thanks for your help !

Please could you share the query that you attempted with distinctCount - I'd expect a distinctCount over a unique column (such as the primary key) to give the result you're hoping for.

Further, please can you expand on "it worked only for greater than 0" - what were the other cases you tried and what happened in those cases - an error? incorrect results? Please share as much detail as you can.

A rough definition of the relevant tables/columns/constraints in your database would also be helpful.
