The DECODE function in Oracle compares an attribute or expression with a series of values and returns an associated value or a default value if no match is found. NVL is used to replace a null value with an alternative value, TO_CHAR is used to convert a value to a character string, and CONVERT is used to convert a value from one character set to another.
