The Pack 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 complements the function Unpack (SQL 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.
- This function requires the UTF8 client character set.
