Postgres functions in the ORM?

Hello everyone, I'm learning typescript and SQL (with drizzle) and I'm trying to make an api endpoint that has something like this

const {name, owner, hidden, uuid} = updateServerDto;
const upd = this.db.execute(
        sql`
        UPDATE ${servers} 
        SET server_name = COALESCE(${name}, server_name), 
            server_owner = COALESCE(${owner}, server_owner),
            hidden = COALESCE(${hidden}, hidden) 
        WHERE server_uuid = ${uuid}
        `,
      );


I'm updating attributes (name, owner, hidden...) that are sent from a PATCH request and some fields are optional so they could be null/undefined. COALESCE() here gives the original value in the column if the attributes are null. This sql query works but I would like to ask if its possible to do this without calling sql`` operator. Earlier i tried something like

const upd = await this.db
        .update(servers)
        .set({
          name: name ? name : servers.name,
          serverOwner: owner ? owner : servers.owner,
        })
        .where(eq(servers.uuid, uuid))


But it did not let me compile, giving me this error instead

error TS2322: Type 'string | PgColumn<{ name: "server_name"; tableName: "servers"; dataType: "string"; columnType: "PgText"; data: string; driverParam: string; notNull: true; hasDefault: false; enumValues: [string, ...string[]]; baseColumn: never; }, {}, {}>' is not assignable to type 'string | SQL<unknown>'.
  Type 'PgColumn<{ name: "server_name"; tableName: "servers"; dataType: "string"; columnType: "PgText"; data: string; driverParam: string; notNull: true; hasDefault: false; enumValues: [string, ...string[]]; baseColumn: never; }, {}, {}>' is not assignable to type 'string | SQL<unknown>'.


If there is a better way to go about what I'm trying to do, any help would be greatly appreciated!
