oracle - Where those sqlplus columns are used? -

just type col in sqlplus returns list of columns, there columns ended _recyc, columns used ? googled not find documentation on them.

column droptime_plus_show_recyc on heading 'drop time' format a19 column objtype_plus_show_recyc on heading 'object type' format a12 column objectname_plus_show_recyc on heading 'recyclebin name' format a30 column origname_plus_show_recyc on heading 'original name' format a16

they're used show recyclebin command. if run headings like:

original name recyclebin name object type drop time ---------------- ------------------------------ ------------ ------------------- ...

if clear columns , run 1 time again get:

origname_plus_show_recyc objectname_plus_show_recyc objtype_plus_show_recyc droptime_plus_show_ -------------------------------- ------------------------------ ------------------------- ------------------- ...

whatever underlying query show recyclebin using (some variant of select .. user_recyclebin presumably) aliasing columns in resultset; sql*plus configured format aliased names.

the other pre-set column definitions similar; example, show edition gives column displayed heading edition, if clear columns reverts underlying name_col_plus_show_edition. _plus_show_ going output show command.
