Sort by To / From in Mail is not working correctly

Question

As an example: I move the mails from the Sent - Gmail folder to a folder I created  On My Mac
In this folder the sorting was by TO but the system did not execute this
Instead it sorted by From and the To was not shown at all !
This is just one example . In general. it sometimes works, but mostly not
It is f ex correct in the Sent Gmail folder or Inbox, but you but those are exceptions.

Answer 1

see whether you find nested table parameter implantation option useful. Also supported by .net/java in case that's your calling appln.
Below is plsql block having a procedure with input paramater of empid's. It returns a cursor( empno and ename) as out parameter.
The empid's are hardcoded in the calling block.
