Drizzle-ORM provides the count of items in a findMany query result

Hello there, I'm currently experimenting with the Drizzle ORM and

imagine I have this specific query

const members = await trx.query.memberTable.findMany({
  with: {
   comments:true
  }
})

I'm wondering how I can retrieve the total count of members from that query?

Answer №1

It seems like you're using the incorrect function to retrieve the number of players. Instead of using findMany which is used to fetch records, you should use players.length to get the count of players (as it's an attribute of the array retrieved from the query). If you only need the number of records, I recommend using the select along with aggregate functions. For more information, check out this link as a helpful reference:

Answer №2

If you need to find the number of players in your database, using the count function is a simple and efficient solution. Here's how you can implement it:

With Drizzle Query:

import { count } from 'drizzle-orm';
await db
  .select({ count: count() })
  .from(playerTable)

In SQL:

select count(*) from playerTable;

If you want to count only the players who have Posts associated with them, you may need to perform a join operation. I usually use the "with" operator for this purpose to fetch associated data instead of just counting records.

Instead of calculating the length and then using FindMany, it makes more sense to utilize the count function. Let Drizzle and your database handle the counting process for you, rather than performing it manually in Typescript.

For more information, you can refer to the documentation:
