Which SQL command uses a wildcard operator?

The use of a wildcard operator is primarily associated with the SQL command that filters results based on pattern matching. In this case, the command involving the "LIKE" operator along with the wildcard character (%) allows for the selection of records where the "BuildingName" begins with the string 'BestHotel', followed by any sequence of characters.

The wildcard operator (%) serves as a placeholder for any number of characters, enabling flexible and dynamic searches within the database. This is particularly useful when you want to retrieve data that meets only part of a specified criterion, which aligns with the functionality of the "LIKE" clause.

In contrast, the other commands do not employ wildcard operators or pattern matching:

• Commands that simply delete, update, or insert data do not utilize pattern matching, focusing instead on specific subsets of data or actions based on exact criteria. Thus, they lack the capability to leverage the flexibility that wildcards provide in searches.
