You have been introduced to various functions used in a SQL statementusually a queryto modify or enhance the way output is represented. Those functions include character, mathematical, and conversion functions. It is very important to realize that the ANSI standard is a guideline for how SQL should be implemented by vendors, but does not dictate the exact syntax or necessarily place limits on vendors' innovations. Most vendors have standard functions and conform to the ANSI concepts, but each vendor has its own specific list of available functions. The function name may differ and the syntax may differ , but the concepts with all functions are the same.
