getBytes(int objNum) - Analytics Database - Teradata Vantage

Returns data that was stored in one of two intermediate aggregate storage areas.

If the specified storage area contains no data, getBytes() returns a null object.

This method is similar to Context.getObject() but provides a faster interface.

Syntax

getBytes(int objNum)

Syntax Elements

objNum

Specifies which aggregation storage area to retrieve intermediate results from, as follows:

Value	Meaning
1	Retrieve intermediate results from the first aggregate storage area. The data that the UDF retrieves was stored from a call to Context.setByte() during a previous aggregation phase. The UDF uses the previously stored data during the Phase.AGR_DETAIL, Phase.AGR_COMBINE and Phase.AGR_FINAL aggregation phases.
2	Retrieve intermediate results from the second aggregate storage area. The data that the UDF retrieves is stored by Vantage. The UDF uses the data during the Phase.AGR_COMBINE aggregation phase.

Exceptions

If the value of objNum is out of range, getBytes() throws an SQLException to indicate that the input parameter of Context.getObject(int) is out of range, setting the SQLException fields as follows.
