Evaluates two Period expressions or derived periods.

Result Type

This predicate applies when both period_expression_1 and period_expression_2 are a period column, period constructor, or period value expression. In this case, the predicate returns True if the end bound value of period_expression_1 is equal to the begin bound value of period_expression_2. If either or both of the operands are NULL, the result is UNKNOWN.
