DROP UNUSED COLUMN
480285Jun 25 2006 — edited Sep 16 2006Dear Gurus
I have a situation where I need to drop specific columns which are set to unused!
Say, I have 3 unused columns in a table and now I want to drop only one unused column from that.
SQL> alter table scott.emptest set unused (ENAME);
Table altered.
SQL> alter table scott.emptest set unused (COMM);
Table altered.
Once I set some columns un-used, now I want to drop only one un-used Column ENAME
SQL> alter table scott.emptest drop column ENAME;
alter table scott.emptest drop column ENAME
*
ERROR at line 1:
ORA-00904: "ENAME": invalid identifier
which in turn throws this error!
Help appreciated!
Thanks in advanced
