Stores intermediate results specified by data into the aggregate storage area.
Each time the UDF is called during the AGR_DETAIL aggregation phase, it must accumulate the row data passed in through arguments into the intermediate aggregate storage area for the specific group. Each group being aggregated to has a separate intermediate storage area.
Arguments
Aggregate UDFs must pass a value of 1 for the objNum argument. Other values are reserved for future releases.
If data specifies a null byte array, setBytes() sets the aggregate storage area to zero.
Exceptions
If the serialized size of data is larger than the size specified in the CLASS AGGREGATE clause of the CREATE FUNCTION or REPLACE FUNCTION statement for the UDF, setBytes() throws an SQLException to indicate an overflow condition, setting the SQLException fields as follows.
