Q:

Which operator performs pattern matching ?

A) LIKE operator B) EXISTS operator
C) BETWEEN operator D) None of these
 
Answer & Explanation Answer: A) LIKE operator

Explanation:

LIKE is a keyword that is used in the WHERE clause. Basically, LIKE allows us to do a search based operation on a pattern rather than specifying exactly what is desired (as in IN) or spell out a range (as in BETWEEN).

 

The syntax is as follows:
SELECT "column_name"
FROM "table_name"
WHERE "column_name" LIKE {PATTERN}

 

{PATTERN} often consists of wildcards.

 

In SQL, there are two wildcards:


% (percent sign) represents zero, one, or more characters.

_ (underscore) represents exactly one character.

Q:

What is function prototyping? What are its advantages?

Answer

Function prototyping is a function declaration statement that tells the compiler about the return type of the function and the number as well as type of arguments required by the function at the time of calling it.


Syntax:


return_type function_name( type1 arg1, type 2 arg2, ... );


 


Advantages of function prototype :


- It helps the compiler in determining whether a function is called correctly or not. Each time when a function is called, its calling statement is compared with its prototype. In case of any mismatch, compiler reports an error.


- A function must be defined before calling it. But prototyping allows a function to be called before defining it.
