Which operator performs pattern matching?

A. BETWEEN operator

B. LIKE operator

C. EXISTS operator

D. None of these

Answer: Option B

Solution(By Examveda Team)

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:

  • 1=% (percent sign) represents zero, one, or more characters.
  • 2=_ (underscore) represents exactly one character.
