Expressions can also use variables. Variables have a Variant data type and the expression evaluator converts the data type of a variable from a Variant subtype to an Integration Services data type before it evaluates the expression. Variables can use only a subset of the Integration Services data types.
The total COST of each cocktail using 2oz whiskey per drink and using the higher estimate of $90 to buy all ingredients, the startup cost comes out to about $7.5/cocktail. After that first bottle of whiskey is gone, you will surely have PLENTY of the other ingredients left.
Bottled Beer. A case of Budweiser costs the bar $20.55, or 85 cents per bottle. (At the closest liquor store, it's $24.99.) The bar sells those bottles for $3.75 apiece, which makes their cost 23 percent of the customer's price.he bar charges $6.75 per dose, so when dealing with Russians or other masochists, the liquor cost is a mere 18 percent. But most people don't drink shots of vodka. All the other crap that goes into a standard mixed drinkâsoda, ice, straws, lime wedgesâis cheap for the bar but free to the consumer.
