Explain system scalar functions?..

Answer / Phool Kunwar

System scalar functions are built-in functions in SQL Server that can be used directly within a SELECT statement. They do not operate on tables, but instead perform calculations or return system values such as current date and time, random number generation, string manipulation, etc.nnExamples include @@IDENTITY, LEN, SUBSTRING, GETDATE, etc.
