Expert Solution & Answer
Chapter 16, Problem 16AW
Explanation of Solution
Result set:
- The “SELECT” statement is been used for selecting data from a
database . - The result table is stored with data and is termed as result set.
- All the fields present in table could be selected using “SELECT” statement.
- Specific fields can be selected by giving particular field names in “SELECT” statement.
Example:
The example for computing “ResultSet” statement is shown below:
ResultSet res = stmt.executeQuery(sql)
Here, “stmt” denotes a valid “Statement” object and “sql” denotes a SQL statement...

SBN Title Author 12345678 The Hobbit J.R.R. Tolkien 45678912 DaVinci Code Dan Brown Your student ID DBS311 Your Name
use the following statement to Write a PL/SQL Function that accepts 4 parameters, 2 strings representing students names, and 2 integers representing the marks they received in DBS311. The function will determine which student had the higher mark and return the name of the student. If the marks were the same, then return the word "same" and return "error" if an error occurs or the calculation can not be determined.
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

This table can be visualized as follows:
