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.
