Output all fields
BRAINscript:
emit *
Python:
ConfigureFields
outputs[0] += inputs[0]
ProcessRecords
outputs[0] += inputs[0]
Specify fields to output
BRAINscript:
emit ‘color’,’type’
Python:
ConfigureFields
outputs[0] += inputs[0]['color']outputs[0] += inputs[0]['type']
ProcessRecords
outputs[0] += inputs[0]
Exclude fields
BRAINscript:
emit*exclude color, type
Python:
ConfigureFields
outputs[0] += inputs[0]outputs[0] -= inputs[0]['color']outputs[0] -= inputs[0]['type']
ProcessRecords
outputs[0] += inputs[0]
Rename a field
BRAINscript:
emit*
rename color as newFieldName
Python:
ConfigureFields
outputs[0] += inputs[0]outputs[0] -= inputs[0]['color']outputs[0]['newFieldName'] = inputs[0]['color']
ProcessRecords
outputs[0] += inputs[0]
outputs[0] -= inputs[0]['color'] must be written before outputs[0]['newFieldName'] = inputs[0]['color']Reversing the order of these statements will produce an incorrect result. In this case, the exclude statement will not only exclude the original field metadata, but will also remove any output field that is mapped from the excluded input field.Create a new field
BRAINscript:
emit*newField1 = field3.toUpperemit newField1
Python:
ConfigureFields
outputs[0] += inputs[0]outputs[0]['newField1'] = unicode
ProcessRecords
outputs[0] += inputs[0]
outputs[0]['newField1'] = fn.upper(inputs[0]['field3'])
