Chapter 15, Problem 2FTE
Explanation of Solution
Given SQL statement:
SELECT * FROM Coffee WHERE ProdNum != ‘14-001’
Not-equal-to operator in SQL:
In SQL not-equal-to operator is “< >”.
- The “< >” operator tests whether one expression is not equal to another expression.
- If any one of the operands or both of the operands are NULL, result is NULL.
- It returns true if both of them have different values.
- It returns false, in case if both values are equal.
SELECT:
- 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.
- The “FROM” denotes a clause to choose from a table.
- The “WHERE” clause specifies that SQL statement should only affect rows with specified criteria.
- The criteria are expressed in form of predicates.
- It is not a mandatory clause, but is used to limit number of rows affected by SQL statement...

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

TAL Distributors would like to know the number of months between the current date and the order date of an order. Write an SQL statement in MySQL that displays the order number and the number of months between the current date and the order date. The number of months should display as an integer. (Hint: You can nest one function within another function.) This is the code I haveSELECT FLOOR(MONTHS_BETWEEN(CURRENT_DATE,To_date(ORDER_DATE, 'MM/DD/YYYY')))num_monthsFROM ORDERS;is giving me an errorError Code: 1305.
