A numeric literal is a string of digits that SQL interprets as a decimal number. A numeric literal can be a: o Decimal string that consists of digits and an optional decimal point. The maximum length, not counting the decimal point, is 19 digits. o Decimal number in scientific notation (E notation) that consists of a decimal string mantissa and a signed integer exponent, separated by the letter E.
