In ABAP SQL, which of the following can be assigned an alias?

In ABAP SQL, naming or assigning an alias is a way to create a temporary name for database objects to make queries easier to read or write. The option that can be assigned an alias is a field from the field list.

When you select fields in a SQL query, you can assign a name to that field which can be referenced later in the results or within the logic of your program. This is particularly useful when performing calculations or when the same field is selected multiple times but under different conditions—giving it a unique alias makes the results clearer and avoids confusion when interpreting the output.

For instance, if you were to perform an operation on a field such as summation, you might want to give it a meaningful name like "Total_Sales" rather than just the field name from the database.

While database tables, order criteria, and group criteria could potentially use aliases in different contexts, they are generally less common in the strict sense of aliasing as applied directly within the field list of a SQL statement. Specifically, database tables typically may not have aliases in the same way that fields do, and while you can refer to ordering and grouping by name indirectly, it is the individual fields in the selection list that are most commonly aliased for
