Expressions

An expression is a series of operands and operators that you specify when you write a program or function script.

Each expression resolves to a particular type of value at run time. A numeric expression resolves to a number; a string expression resolves to a series of characters; a logical expression resolves to true or false; a datetime expression resolves to a date, interval, time, or timestamp.
