Question

Unlike other database objects, when you invoke a user-defined function you must always include the ______________________________.

Answer 1

In databases, a user-defined function is invoked by including the function's name and the parentheses, potentially with arguments if necessary.

Step-by-step explanation:

When you invoke a user-defined function in a database, you must always include the function's name and the parentheses (), which may include arguments if the function requires them. This is a contrast to other database objects such as tables or views which do not require parentheses when referenced. User-defined functions (UDFs) can be scalar, returning a single value, or table-valued, returning a table data type. For instance, if there is a function that calculates the area of a circle, you would invoke it as CalculateArea(radius), where 'CalculateArea' is the function name and 'radius' is the argument.
