# Demonstration of broken LQ behaviour

## Prepare

- Make sure Deno is installed

- Make sure SurrealDB is installed

## To run

- First, start SurrealDB (if you haven't already)

  - `deno task dev:surreal`

  - Or otherwise have a DB instance running with the options configured in the `main.ts` file.

- Second, run the script

  - Once: `deno task dev`

  - Watch mode: `deno task dev:watch` (will rerun everytime you save the `main.ts` file)

## Issue this script demonstrates

This demo demonstrates two issues:

- We have a live query named "LIVE". This LQ has a `WHERE` clause which filters only people that are verified.

  - It fails to send any deletions to the client, which could be explained by maybe the filter being applied to the deleted record (where the data does not exist anymore)

- We have a live query named "NONE". This LQ has a `WHERE` clause which filters only people where `verified` is `NONE`.

  - This sends through only all the deletions, which demonstrates that the filters for deletions are applied to the deleted record (where the data does not exist anymore)

- We have a live query named "ALTQ". This LQ does not have any filters and will send over every message coming through.
