Syntax

{BYTE-CO|BYTE-CN|BYTE-CA|BYTE-NA|BYTE-CS|BYTE-NS}

Effect
Comparison expressions join two or more operands with a relational operator to make a relational expression and produce a logical value
as the result of the comparison.

The operands are compared using one of the relational operators shown here.

The comparisons follow comparison rules .

operand1 , operand2 , and operand are general expression positions , which means that the following can be specified:

Data objects

Predefined functions

Functional methods

Calculation expressions

Constructor expressions

Table expressions

When a predefined function, a functional method, or a constructor expression is specified, its return value or result is used as an operand. When a calculation expression is specified, its result is used. A single operand can be compared with all single operands listed in the comparison rules for single operands . A calculation expression can be compared with all single operands or comparisons listed in the comparison rules for calculation expressions .
