Which operator performs pattern matching in SQL?

Question

A) BETWEEN operator

B) LIKE operator

C) EXISTS operator

D) None of these

Answer 1

The operator that performs pattern matching in SQL is option B) LIKE operator. The BETWEEN operator checks for values within a range, while the EXISTS operator checks for the existence of rows in a subquery. The LIKE operator, on the other hand, is specifically designed for pattern matching. It uses wildcard characters such as "%" and "_" to search for values that match a specified pattern. With the LIKE operator, you can perform pattern-based searches in SQL, making it the correct choice for this question.

Answer 3

The operator that performs pattern matching in SQL is option B) LIKE operator.

The BETWEEN operator is used to check if a value lies within a specified range, rather than performing pattern matching.

The EXISTS operator is used to check for the existence of rows in a subquery, and it does not perform pattern matching.

In contrast, the LIKE operator is specifically designed for pattern matching in SQL.

It allows you to search for values that match a specified pattern using wildcard characters such as "%" and "_".

The "%" wildcard represents zero or more characters, while the "_" wildcard represents a single character.

For example, you can use the LIKE operator to find all names starting with "J" by using the pattern "J%".

Similarly, you can use it to find all names with exactly five characters by using the pattern "_____".

Therefore, the LIKE operator is the correct choice for performing pattern matching in SQL.
