Testing

Manually tested via the following:

dbt run
dbt test

Gotchas

1. MySQL only has 2 levels (catalog/database/schema + relation) rather than the 3 levels (catalog + schema + relation) that most have. I think that Spark and/or Snowflake might be similar.
2. MySQL doesn't allow quoted identifiers with double-quotes
   • Need to set quoting parameters to false
3. pyodbc doesn't allow multiple statements (and doesn't allow begin/end outside of functions)
   • Need to execute each statement separately
