This makes users who are unfamiliar with SQL and Datasette think the canned query page is broken and is a frequent source of confusion.

To anyone dealing with this: My solution is to modify the canned query so that it returns no results which cues people to fill in the blank parameters.

So instead of `emails_fts match escape_fts(:search))`

My canned queries now look like this:

`emails_fts match escape_fts(iif(:search=="""", ""*"", :search))`

There are no asterisks in my data so the result is always blank.

Ultimately it would be nice to be able to handle this in the metadata. Either making some named parameters required or setting some default values.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",828858421,

```yaml
databases:
  fixtures:
    queries:
      neighborhood_search:
        params:
        - text

In addition to being able to specify defaults, I'd also like to add other things in the future - most significantly the ability to specify a different input widget (e.g. textarea v.s. single-line input)

So maybe this looks like:
```yaml
params:
- name: text
  default: """"
- name: age
  widget: number
