A multiple-input SQL-MapReduce function operates on at least two input data sets. There are two alternatives for organizing the inputs:

  • For the first input, specify PARTITION BY ANY; for the others, specify DIMENSION.
  • For the first input, specify PARTITION BY p_attribute_set; for the others, specify either PARTITION BY p_attribute_set or DIMENSION.
