Students have asked these similar questions
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
