In SQL (including PROC SQL), the correct syntax for creating a calculated column with an alias is to place the expression first, followed by the AS keyword and the column name. The syntax 'price-cost as Profit' calculates the difference and names it Profit. Other options either use incorrect operator placement or improper alias syntax.
To create a new column named Profit by subtracting the values of the column Cost from those of the column Price, you can use the following code:
SELECT fruit, cost, price, price - cost AS Profit
Option A) Profit = price - cost - This option is incorrect because it uses the wrong syntax for assigning a name to the new column. The correct syntax is "column_name AS alias_name".
Option B) price - cost AS Profit - This option is correct because it subtracts the value of the column Cost from the column Price and assigns the result to a new column named Profit.
Option C) profit = price - cost - This option is incorrect because it uses the wrong syntax for assigning a name to the new column. The correct syntax is "column_name AS alias_name".
Option D) Profit as price - cost - This option is incorrect because it uses the wrong syntax for subtracting the values of the column Cost from those of the column Price. The correct syntax is "column_name - column_name".
Therefore, the correct answer is B) price - cost as Profit.
