public class MatchRowTimeFunction extends BuiltInSqlFunction
The function used to access a rowtime attribute with TIMESTAMP or TIMESTAMP_LTZ type from MATCH_RECOGNIZE clause. The function accepts zero or one operand which is a field reference with rowtime attribute. If there is no operand, the function will return rowtime attribute with TIMESTAMP type. Otherwise, the return type will be same with the operand type.
