To call a function, SQL Server uses the following syntax:

SELECT dbo.GetSquare(Item) AS SquareValue 
FROM Squares;

In Oracle the same can be achieved with:

SELECT GetSquare(Item) AS SquareValue 
FROM Squares;

The syntax is almost the same, except SQL Server requires the schema (dbo.) before the function name.

Is it possible to write an identical statement to call a function for both DBMS in 2024?
