```sql
select
  'contains_non_integer' as result
from
  mytable
where
  cast(cast(mycolumn AS INTEGER) AS TEXT) != mycolumn
limit
  1
```
This will return a single row with a 1 as soon as it comes across a column that contains a non-integer - so it short circuits quickly on TEXT columns with non-integers in them.

If everything in the column is an integer it will scan the whole thing before returning no rows.

More extensive demo:
```sql
select
  value,
  cast(cast(value AS INTEGER) AS TEXT) = value as is_valid_int
from
  (
    select
      '1' as value
    union
    select
      '1.1' as value
    union
    select
      'dog' as value
    union
    select
      null as value
  )

Thanks so much for all your work on datasette, it's an excellent project and I wish you all the best with it. I particularly enjoyed your talk at the Django London Meetup a short while back. 

I've been trying to publish to Heroku from Windows 10 and I was running into this error. I'm not sure why it can't be run without `shell=True` on Windows but this seems to help. With this change, I am able to publish if I pass in a `name` to the `publish` command. When a `name` is not passed the default of `datasette` is used and therefore this line here fails (as datasette at heroku already exists) and causes the recession error mentioned above.

https://github.com/simonw/datasette/blob/9a6d0dce282e7fb58c5610e24c74098c923abfdc/datasette/publish/heroku.py#L126

I tried to write a patch for this but I am really struggling with being on Windows (many of the tests seem to fail anyway?), and my lack of knowledge of Mock, so sorry for this. Hope this is of some help.
