Boolean Value Expressions (Search Conditions)

Boolean Value Expressions (Search Conditions)

Boolean value expressions are used in Data Vault Service SQL to specify a
search condition
that can be used in SELECT statements. These expressions use various
predicates
to test a particular operand (for example, the contents of a column) for membership in a specified set of values. If the operand satisfies the condition, it is TRUE; if it does not satisfy the condition, it is FALSE; a NULL value can force a Boolean expression to evaluate to UNKNOWN.
When the NOT operator is used, the following Boolean values are equivalent:
  • NOT TRUE is FALSE
  • NOT FALSE is TRUE
  • NOT UNKNOWN is UNKNOWN
