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.
