Declaring Constants:
A constant holds a value that does not change.
The information in "Declaring Variables" also applies to constant declarations, but a constant declaration has two more requirements: the keyword CONSTANT and the initial value of the constant. (The initial value of a constant is its permanent value.)
Example Constant Declarations:
This example declares three constants with scalar data types.
DECLARE
credit_limit CONSTANT REAL := 5000.00; -- SQL data type
max_days_in_year CONSTANT INTEGER := 366; -- SQL data type
urban_legend CONSTANT BOOLEAN := FALSE; -- PL/SQL-only data type
BEGIN
NULL;
END;
