Class TimestampColSubtractTimestampScalar

java.lang.Object

org.apache.hadoop.hive.ql.exec.vector.expressions.VectorExpression

org.apache.hadoop.hive.ql.exec.vector.expressions.gen.LongColSubtractLongScalar

org.apache.hadoop.hive.ql.exec.vector.expressions.gen.TimestampColSubtractTimestampScalar

All Implemented Interfaces:

Serializable

public class TimestampColSubtractTimestampScalar
extends LongColSubtractLongScalar

Generated from template DTIColumnArithmeticDTIScalarNoConvert.txt, which covers arithmetic expressions between a datetime/interval column and a datetime/interval scalar. No type conversion is needed, the operations can be performed using the vectorized long value
