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.
To use Pack_MLE and Unpack_MLE together, you must run both on ML Engine platform. Pack_MLE and Unpack_MLE are incompatible with Advanced SQL Engine Pack and Unpack functions.
Before packing columns, note their data types—you need them if you want to unpack the packed column.
