Explanation:
The NULLIF Function
The NULLIF function tests two terms for equality. If they are equal the function returns a null, else it returns
the first of the two terms tested. The NULLIF function takes two mandatory parameters of any data type.
The syntax is NULLIF(ifunequal, comparison_term), where the parameters ifunequal and comparison_term
are compared. If they are identical, then NULL is returned. If they differ, the ifunequal parameter is
returned.

Explanation:
So, how are words that contain single quotation marks dealt with? There are essentially two mechanisms
available. The most popular of these is to add an additional single quotation mark next to each naturally
occurring single quotation mark in the character string Oracle offers a neat way to deal with this type of
character literal in the form of the alternative quote (q) operator. Notice that the problem is that Oracle
chose the single quote characters as the special pair of symbols that enclose or wrap any other character
literal. These character- enclosing symbols could have been anything other than single quotation marks.
Bearing this in mind, consider the alternative quote (q) operator. The q operator enables you to choose
from a set of possible pairs of wrapping symbols for character literals as alternatives to the single quote
symbols. The options are any single-byte or multibyte character or the four brackets: (round brackets),
{curly braces}, [squarebrackets], or <angle brackets>. Using the q operator, the character delimiter can
effectively be changed from a single quotation mark to any other character
The syntax of the alternative quote operator is as follows:
q’delimiter’character literal which may include the single quotes delimiter’ where delimiter can be any
character or bracket.
Alternative Quote (q) Operator
Specify your own quotation mark delimiter.
Select any delimiter.
Increase readability and usability.
SELECT department_name || q'[ Department’s Manager Id: ]’ || manager_id
AS “Department and Manager”
1Z0-061 vce FROM departments;
Alternative Quote (q) Operator
Many SQL statements use character literals in expressions or conditions. If the literal itself contains a
single quotation mark, you can use the quote (q) operator and select your own quotation mark delimiter.
You can choose any convenient delimiter, single-byte or multi byte, or any of the following character pairs:
[ ], { }, ( ), or < >.
In the example shown, the string contains a single quotation mark, which is normally interpreted as a
delimiter of a character string. By using the q operator, however, brackets [] are used as the quotation
mark delimiters. The string between the brackets delimiters is interpreted as a literal character string

That is notably true in case if you’re going for the Oracle 1Z0-061 dumps certification by training. Some individuals are fortunate enough to know which Oracle https://www.pass4itsure.com/1Z0-061.html certification they will do it.
