Question

To be able to do wildcard searches with the where command, this operator must be used.

a) like
b) wildcard
c) *
d) match

Answer 1

The correct operator for performing wildcard searches in an SQL WHERE clause is 'like'. It is used with '%' and '_' as wildcard characters to match patterns of characters within fields.

Step-by-step explanation:

When performing wildcard searches in SQL using the WHERE clause, the correct operator to use is LIKE. This operator is designed to filter the result set to only include rows that match a specified pattern. The wildcard characters that are commonly used with the LIKE operator are %, which matches any sequence of characters, and _, which matches any single character.

For example, the query SELECT * FROM users WHERE name LIKE 'Sam%' would find all users with names that start with 'Sam' followed by any number of characters.
