dear all

i am aware that HANA can unload and load tables in their entirety.

i also understand that HANA can load columns individually.

but what i don't see anywhere, is the ability or said functionality of HANA, being able to unload individual columns.

here's what is present in the admin guide

-------------------------------------------

Load/Unload a Column Table into/from Memory

Under normal circumstances, the SAP HANA database manages the loading and unloading of tables into and from memory independently, the aim being to keep all relevant data in memory. However, you can manually load and unload individual tables, as well as load table columns if necessary.

-------------------------------------------

so what i take from above, is

     you can unload, and load individual tables

     you can load individual columns

what it does not say, is that you can unload individual columns, so ... can it be done ?

i am aware of the view M_CS_UNLOADS/LOADS, that are on a column granularity, but i cannot see or test easily, if entries in these views, for the tables are missing a column, that exist in the table's definition.

i only notice that all columns, for a table are present in these views, at any particular load/unload event time.

i hope i have explained myself clearly, and look forward to your replies.

thanks
