I have a table (dbo.beer) with this data:
| BeerID | BeerName | brewer | beerdescription |
| ----------- | -------------------- | -------------------- | ---------------------------------------------------------------------------------- |
| 1 | Becks | Interbrew | Beck's is a German-style pilsner beer known for its golden color, full-bodied taste, and a crisp, clean finish with floral and fruity hop aromas, brewed according to the German purity law |
| 2 | Fat Tire | New Belgium | Toasty malt, gentle sweetness, flash of fresh hop bitterness. The malt and hops are perfectly balanced. |
| 3 | Mac n Jacks | Mac & Jack's Brewery | This beer erupts with a floral, hoppy taste, followed by a well rounded malty middle, finishing with a nicely organic hop flavor. Locally sourced two row grain and a blend of specialty malts give our amber its rich taste. |
| 4 | Alaskan Amber | Alaskan Brewing | Alaskan Brewing Amber Ale is an "alt" style beer, meaning it's fermented slowly and at colder temperatures, resulting in a well-balanced, richly malty, and long-lasting flavor profile with a clean, pleasing aftertaste. |
| 8 | Kirin | Kirin Brewing | Kirin Ichiban is a Lager-type beer, which means it is fermented at low temperatures and offers a light and refreshing texture with a smooth and balanced flavor. |
CREATE TABLE [dbo].[Beer] ( [BeerID] [int] NOT NULL IDENTITY(1, 1), [BeerName] [varchar] (20) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [brewer] [varchar] (20) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [beerdescription] [varchar] (max) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] GOI run this code:
SET TEXTSIZE 20; SELECT b2.BeerName , b2.beerdescription FROM dbo.Beer AS b2; GOWhat is returned? See possible answers
