What is the primary function of the SQL SELECT * query?

The SQL SELECT * query is primarily used to retrieve all fields from a specified table within a database. When executed, this query will return every column for every record in the indicated table, which can be particularly useful for viewing the entirety of the data present in that table without needing to specify individual column names. This command is essential for data retrieval, allowing users to quickly gather and inspect all available information in a straightforward manner.

In contrast, other options represent different SQL functions. For instance, inserting new records is handled by INSERT statements, deleting records requires DELETE statements, and updating existing records is accomplished with UPDATE statements. Each of these functions serves a distinct purpose related to data manipulation in a database, whereas the SELECT * query's exclusive role is to retrieve information.
