Question
The SQL keyword(s) ________ is used with wildcards.
- NOT IN only
- LIKE only
- IN and NOT IN
- IN only
Solution
Breakdown of the Problem
- We need to identify the SQL keyword that is used with wildcards.
- We have several options to analyze.
Relevant Concepts
- Wildcards in SQL are used in conjunction with the
LIKE
keyword to search for a specified pattern in column data. - Common wildcard characters include
%
(which represents zero or more characters) and_
(which represents a single character).
Analysis and Detail
- LIKE: This keyword is specifically designed to work with wildcards. For example,
SELECT * FROM users WHERE username LIKE 'a%'
retrieves all usernames starting with 'a'. - IN: This keyword is used to specify multiple values in a
WHERE
clause, but it does not function with wildcards. - NOT IN: Similar to
IN
, it is used for negation and does not use wildcards. - NOT LIKE: This is the negation of
LIKE
, but the question does not provide it as an option.
Verify and Summarize
Among the options given, LIKE only is the correct answer since it is directly associated with the use of wildcards in SQL queries.
Final Answer
The SQL keyword used with wildcards is LIKE only.
