EXEC('ALTER TABLE dbo.stg_things addd primary key(thing_id)')

This command will fail due to addd being incorrect. This will just keep chugging along, is that just a side affect of EXEC that we have to live with? I'm going to attempt to not use EXEC, but I was warry when I read #80

Still new to DBT so I'm not certain how everything's supposed to work, but this almost certainly shouldn't happen. If a SQL command fails something should throw an error
