**In SQL** Write a SELECT statement that returns these columns: InstructorDept The DepartmentName column from the Departments table for a related instructor LastName The LastName column from the Instructors table FirstName The FirstName column from the Instructors table CourseDescription The CourseDescription column from the Courses table CourseDept The DepartmentName column from the Departments table for a related instructor Return one row for each course that’s in a different department than the department of the instructor assigned to teach that course. (Hint: You will need to join the Departments table to both the Instructors table and the Courses table, which will require you to use table aliases to distinguish the two tables.)
PATHS is a table that contains information about paths on a number line. The structure of PATHS is as follows, where x1 and x2 represent that there is a path from Coordinate x1 to Coordinate x2 (You can't move from Coordinate x2 to Coordinate x1 ). NAME ΤΥΡE NULLABLE X1 INT FALSE X2 INT FALSE Problem Please write an SQL statement that returns the beginning and end point of each path in PATHS . Sort them by the value of the beginning point in ascending order. Constraints • In the case where a direct path from Coordinate a to Coordinate b is available, no path from Coordinate b to Coordinate a will be given. |x1-x2| = 1 • No path will overlap with one another. Example Suppose that PATHS is as follows: x1 x2 1 2 2 3 4 7 7 6 This table can be visualized as follows: START END END START 7 8. 9 Therefore, your SQL statement must return the following: start end 1 4 8 6

And based on these conditions either employee gets raise or not get raise. If employee salary is less than 5000 and also if employees managers is either 101 or 124 then it means employee is due for raise otherwise employee is not due for raise Sample…
