How do you move a partitioned table from one tablespace to another in Oracle 11g?

Question

I have a partitioned table that belongs to tablespace report. I want to move it to tablespace record instead.

One possibility is to drop the table and

You have to consider indexes that may be invalidated as well - to cover your question about resetting the default tablespaces in addition to this, I think this is the full process that you'll want to implement:

1) Move partitions (a PL/SQL loop as per zürigschnäzlets' answer)

These are procedures I use within an anonymous block wrapper that defines a_tname, a_destTS, vTname, and vTspName - they should give you the general idea:

procedure mvTabPart (a_tname in varchar2, a_destTS in varchar2) is
cursor pCur(vTname varchar2, vTspName varchar2) is
  select table_name, partition_name
  from user_tab_partitions
  where table_name = vTname
      and tablespace_name not like vTspName
  order by partition_position desc;
begin
for pRow in pCur(a_tname, a_destTS) loop
 sqlStmnt := 'alter table '||pRow.table_name||
             ' move partition '||pRow.partition_name||
             ' tablespace '||a_destTS;
execute immediate sqlStmnt;
end loop;
end mvTabPart;

2) Set table default partition tablespace so new partitions are created there:

    procedure setDefTabPart (a_tname in varchar2, a_destTS in varchar2) is
    cursor tCur(vTname varchar2) is
      select table_name
      from user_part_tables
      where table_name = vTname;
    begin
    for tRow in tCur(a_tname) loop
     sqlStmnt := 'alter table '||tRow.table_name||
                 ' modify default attributes '||
                 ' tablespace '||a_destTS;
    execute immediate sqlStmnt;
    end loop;
end setDefNdxPart;

3) Set index default partition tablespace so new index partitions (if any) are created where you want them:

procedure setDefNdxPart (a_tname in varchar2, a_destTS in varchar2) is
cursor iCur(vTname varchar2) is
  select index_name
  from user_part_indexes
  where index_name in (select index_name
             from user_indexes where table_name = vTname);
begin
for iRow in iCur(a_tname) loop
 sqlStmnt := 'alter index '||iRow.index_name||
             ' modify default attributes '||
             ' tablespace '||a_destTS;
execute immediate sqlStmnt;
end loop;

end setDefNdxPart;

4) rebuild any partitioned indexes that need rebuilding and are not in the desired tablespace:

procedure mvNdxPart (a_tname in varchar2, a_destTS in varchar2) is
cursor ndxCur(vTname varchar2, vTspName varchar2) is
select i.index_name index_name, ip.partition_name partition_name
  from user_ind_partitions ip, user_indexes i
  where i.index_name = ip.index_name
     and i.table_name = vTname
     and i.partitioned = 'YES'
     and (ip.tablespace_name not like vTspName or ip.status not like 'USABLE')
  order by index_name, partition_name ;
begin
for ndxRow in ndxCur(a_tname, a_destTS) loop
 sqlStmnt := 'alter index '||ndxRow.index_name||
             ' rebuild partition '||ndxRow.partition_name||
             ' tablespace '||a_destTS;
execute immediate sqlStmnt ;
end loop;
end mvNdxPart;

5) Rebuild any global indexes

procedure mvNdx (a_tname in varchar2, a_destTS in varchar2) is
cursor ndxCur(vTname varchar2, vTspName varchar2) is
  select index_name
  from user_indexes
  where table_name = vTname
       and partitioned = 'NO'
       and (tablespace_name not like vTspName or status like 'UNUSABLE')
  order by index_name ;
begin
for ndxRow in ndxCur(a_tname, a_destTS) loop
 sqlStmnt := 'alter index '||ndxRow.index_name||
             ' rebuild tablespace '||a_destTS;
execute immediate sqlStmnt ;
end loop;
end mvNdx;
