I use DataGrip as an IDE for Google BigQuery. DataGrip has a warning pane that warns about items that are frivolous. An example below, "Unable to resolve column 'DAYS_DIFF_CURRENT_ETA', this is occurring because I capitalized the word when I was selecting it.
The query runs fine, however I would prefer to only see warnings where my query may not execute due to an error in how I wrote it.
