Error creating nested table column storage table - sql

Question

Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
Seeking help from experts to resolve the following error:
CREATE TABLE "ABC"
(----
----
"STATUSES" "INTLIST" ,
----
"CHAIN_DETAILS" "CHAIN_CFG_LIST" ,
-----
)
NESTED TABLE "STATUSES" STORE AS "OP_STATUSES_NT"
RETURN AS VALUE
NESTED TABLE "CHAIN_DETAILS" STORE AS "op_chains"
RETURN AS VALUE;
Gives error message:
ORA-02320: Error creating nested table column storage table STATUSES
ORA-01950: no permissions for tablespace

Answer 1

My guess is the user has no quota on the default tablespace. You can find your default tablespace by querying user_users, or dba_users if checking a different user, and the quota from user_ts_quotas or dba_ts_quotas. A value of -1 means unlimited. Join these to see your quota for the default tablespace:
select u.username
, u.default_tablespace
, tq.max_bytes
from user_users u
left join user_ts_quotas tq
on tq.tablespace_name = u.default_tablespace;
This will be a problem for any table, but if deferred_segment_creation is set to true (the default) then the error will only appear when you attempt to add a row to the table, as this is the first request for storage.
Now that I check, it seems a nested table requires storage immediately, which could explain why you get the error for a nested table column.
Example using test user 'demo':
sqlplus / as sysdba

DEMO USERS
My default tablespace is USERS and I have no quota on it, but I can create a table:
SQL> create table demotable(id integer);
Table created.
I only have a problem when I need some actual storage:
SQL> insert into demotable values (1);
insert into demotable values (1)
*
ERROR at line 1:
ORA-01950: no privileges on tablespace 'USERS'
Now try with a nested table:
SQL> create or replace type demo_tt as table of number(1);
2 /
Type created.
SQL> create table abc
2 ( id integer
3 , statuses demo_tt )
4 nested table statuses store as op_statuses_nt return as value;
create table abc
*
ERROR at line 1:
ORA-02320: failure in creating storage table for nested table column STATUSES
ORA-01950: no privileges on tablespace 'USERS'
My user demo needs a quota on tablespace USERS (normally you grant unlimited or nothing, but just for fun let's allocate 1MB...)
SQL> conn / as sysdba
Connected.
SQL> alter user demo quota 1M on users;
User altered.
SQL> conn demo/demo
Connected.
SQL> select u.username
2 , u.default_tablespace
3 , tq.max_bytes
4 from user_users u
5 left join user_ts_quotas tq
6 on tq.tablespace_name = u.default_tablespace;
USERNAME DEFAULT_TABLESPACE MAX_BYTES

Retry the table creation:
SQL> create table abc
2 ( id integer
3 , statuses demo_tt )
4 nested table statuses store as op_statuses_nt return as value;
Table created.
SQL> insert into abc (id, statuses) values (1, demo_tt(1,2,3));
1 row created.
