An operator manipulates individual data items and returns a result. The data items are called operands or arguments. Operators are represented by special characters or by keywords. For example, the multiplication operator is represented by an asterisk (*) and the operator that tests for nulls is represented by the keywords IS NULL.
2.2 Arithmetic Operators
Arithmetic operators manipulate numeric operands. The '-' operator is also used in date arithmetic. Supported arithmetic operators are listed in Table 2-2.
2.3 Character Operators
Character operators used in expressions to manipulate character strings are listed in Table 2-3.
2.4 Comparison Operators
Comparison operators used in conditions that compare one expression with another are listed in Table 2-4. The result of a comparison can be TRUE, FALSE, or UNKNOWN.
2.5 Logical Operators
Logical operators which manipulate the results of conditions are listed in Table 2-5.
