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.
Typical costs: 1  On the low end, a champagne toast with a $5 per bottle California sparkling wine and basic flutes might cost $1.50 per person. 2  In the mid-range, a toast with a $14 per bottle Spanish cava might cost $3 per person.  And, on the high end, a toast with $40-plus champagne from France in crystal flutes might cost $7 or more per person.
