Expressions
An expression is a randomly complex combination of the constants, variables, literals, operators, & function calls. The simplest expression is the single variable. The PL/SQL compilers determine the datatype of an expression from the types of the constants, variables, literals, and operators which comprise the expression. Every time the expression is computed, a single value of that type results.
