ComparisonOperator enum

A comparison operator is an enumeration of several operations:

  • EQ for equal.
  • NE for not equal.
  • IN checks for exact matches.
  • LE for less than or equal to.
  • LT for less than.
  • GE for greater than or equal to.
  • GT for greater than.
  • BETWEEN for between.
  • NOT_NULL for exists.
  • NULL for not exists.
  • CONTAINS for substring or value in a set.
  • NOT_CONTAINS for absence of a substring or absence of a value in a set.
  • BEGINS_WITH for a substring prefix.
Scan operations support all available comparison operators.

Query operations support a subset of the available comparison operators: EQ, LE, LT, GE, GT, BETWEEN, and BEGINS_WITH.
