The Pack_MLE function packs data from multiple input columns into a single column. The packed column has a virtual column for each input column. By default, virtual columns are separated by commas and each virtual column value is labeled with its column name.
Pack_MLE complements the function Unpack_MLE (ML Engine), but you can use it on any columns that meet the input requirements.
Before packing columns, note their data types—you need them if you want to unpack the packed column.
