Answer:

SELECT empID FROM personnel WHERE hourlyWage > 15.00 AND hourlyWage <= 18.00

Explanation:

  • In SQL, SELECT is used to display particular rows and columns or all columns and rows based on conditions imposed. * is used to all columns otherwise column names to be displayed are mentioned.
  • WHERE condition is used to impose conditions on rows to display. For eg. to display employees having salary less than 40,000,etc.
  • BETWEEN clause is also used to filter out a range but the values are inclusive both start and end. For example - BETWEEN 20 AND 40 , then rows with value 20 and 40 are also included.
  • But in this query we need to find hourlwage >15 so we did not use BETWEEN clause and manually checked conditions for >15 and <=18 and joined them using AND keyword.
