You are creating a PROC SQL query that will list all employees who have spent (or overspent) their allotted 120 hours of vacation for the current year. The hours that each employee used are stored in the existing column Spent. Your query defines a new column, Balance, to calculate each employee’s balance of vacation hours. Which query will produce the report that you want?

  1. proc sql; select name, spent, 120-spent as calculated Balance from Company.Absences where balance <= 0;

  2. proc sql; select name, spent, 120-spent as Balance from Company.Absences where calculated balance <= 0;

  3. proc sql; select name, spent, 120-spent as Balance from Company.Absences where balance <= 0;

  4. proc sql; select name, spent, 120-spent as calculated Balance from Company.Absences where calculated balance <= 0;

B Correct answer
Explanation

Use the CALCULATED keyword to reference a computed column in the WHERE clause. Option B correctly uses 'where calculated balance <= 0' to filter on the derived Balance column. Options A and C omit the required CALCULATED keyword, while Option D incorrectly places it in the SELECT clause.
