Computer Science please please any help ASAP Query #5: Code a query that will make use of SQL Server intrinsic functions and reference the Instructors table. Must have alias names for each column. First column: Display the instructors name as first name initial followed by a period and space and then last name such as B. Brown Second column: Display the year only for the hire date. Third column: Difference in months between today’s date and the hire date. Last column: Display the string literal ‘Full-time instructor’ if an instructor has a Status of F or return the string literal of ‘Adjunct instructor’ if they have a status of P. You can use the Case function or the IIF function.
