rel_exp - Relational Expressions

Syntax

... { operand1   {=|EQ|<>|NE|>|GT|<|LT|>=|GE|<=|LE}
               | {CO|CN|CA|NA|CS|NS|CP|NP}
               | {BYTE-CO|BYTE-CN|BYTE-CA|BYTE-NA|BYTE-CS|BYTE-NS}
               | {O|Z|M} operand2 }
  | { operand [NOT] BETWEEN operand1 AND operand2 }
  | { operand [NOT] IN seltab }  ... .

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.

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

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.
