This check is incorrect. There are parameters which default to none value (e.g. https://docs.snowflake.com/en/sql-reference/parameters#query-tag).

Hey @Richard-Barrett 👋
Thank You for your contribution. We can merge the change after you apply the change proposed by @sfc-gh-asawicki. Just a reminder for future contributions, please familiarize yourself with our contribution guideline. We highly recommend reaching out to the team (could be through GitHub issue or any other way) before creating such change as this one. This change provides value to the provider, but we will be refactoring this part soon and it will be entierely changed due to the fact that SET shouldn't be used in Delete operation (it should be UNSET which is not yet supported by our SDK). Anyway, please consult with us the change next time and again Thank You for helping us :)
