Using `.orderBy` in JSON

Hey, I have a schema that roughly looks like this

export interface Member {
    id: string;

    activity: {
        messages: number;
    };
}

export interface Member {
    id: string;

    activity: {
        messages: number;
    };
}

and I want to query the db like that it gives me the top 10 Members with the highest activity.messages count. I figured out how I can orderBy but not inside of a json.

Deleting multiple rows at once

I have a question, if I have like

await db
  .deleteFrom('person')
  .where('groupId', '=', id)
  .execute();

await db
  .deleteFrom('person')
  .where('groupId', '=', id)
  .execute();

would that delete ALL persons that have that groupId, or just one of them?

JSON in columns (postgresql)

Hey <a:YA_Wave:743393941369651201> I am completely new to using SQL databases and have a (hopefully) simple question. I want to store JSON inside a column and want to make certain keys not null and/or set a default value, how would I do that? In this case, I have a language column and want to set a default value for the locale key This is my UserTable type:

export interface UserTable {
    _id: Generated<Buffer>
    userId: string;

    language: {
        locale: string;
        // other things
    };

    created_at: ColumnType<Date, string, never>
}

export interface UserTable {
    _id: Generated<Buffer>
    userId: string;

    language: {
        locale: string;
        // other things
    };

    created_at: ColumnType<Date, string, never>
}

This is the current state of my migrations/0-initials.ts

import { ColumnDefinitionBuilder, Kysely, sql } from "kysely";

export async function up(db: Kysely<any>): Promise<void> {

    await db.schema
        .createTable("users")
        .addColumn("_id", sql`binary(16)`, (col: ColumnDefinitionBuilder) => col.primaryKey().defaultTo(sql`(uuid_to_bin(uuid()))`))
        .addColumn("userId", "varchar(40)", (col) => col.notNull().unique())

        // how would I add a default value to 'language.locale' ?
        .addColumn("language", "json", (col) => col)
        
        .execute();

}

import { ColumnDefinitionBuilder, Kysely, sql } from "kysely";

        .createTable("users")

        .addColumn("userId", "varchar(40)", (col) => col.notNull().unique())

        // how would I add a default value to 'language.locale' ?
        .addColumn("language", "json", (col) => col)
        
        .execute();

}

(stripped things away that are not needed for this post) Thanks love
