Stupid Query

Question

Hi,
please help me.. I'm getting crazy in writing this query:
select 'ALTER TABLE ' || ds.segment_name || ' MOVE TABLESPACE ' ||
case when dt.blocks*v.value <= 5242880 then 'SMALL_DATA'
else 'LARGE_DATA'
end || ';'
from dba_segments ds, dba_tables dt, v$parameter v
where 1=1
and v.name='db_block_size'
and ds.segment_type = 'TABLE'
and ds.owner = 'GHADDART'
--and ds.owner = dt.owner
and ds.segment_name = dt.table_name
and DS.TABLESPACE_NAME = DT.TABLESPACE_NAME
and (dt.blocks*v.value) IS not NULL;
This works...
ALTER TABLE ACTCIFCOGNOMENOME MOVE TABLESPACE LARGE_DATA;
ALTER TABLE ACTCIFNOMECOGNOME MOVE TABLESPACE LARGE_DATA;
ALTER TABLE ACTCIFNOME_COGNOME MOVE TABLESPACE LARGE_DATA;
ALTER TABLE AC_ACCOUNTS MOVE TABLESPACE LARGE_DATA;
ALTER TABLE AC_JOINTACC MOVE TABLESPACE LARGE_DATA;
ALTER TABLE CHANGES_FREEZE_LIST_20030922 MOVE TABLESPACE SMALL_DATA;
ALTER TABLE CHANGES_FREEZE_LIST_20031017 MOVE TABLESPACE SMALL_DATA;
ALTER TABLE CHFL_20030922 MOVE TABLESPACE SMALL_DATA;
ALTER TABLE CHFL_20031017 MOVE TABLESPACE SMALL_DATA;
ALTER TABLE COFL_20030922 MOVE TABLESPACE SMALL_DATA;
ALTER TABLE COFL_20031017 MOVE TABLESPACE SMALL_DATA;
ALTER TABLE DM_PERS MOVE TABLESPACE LARGE_DATA;
ALTER TABLE LISTA_SITO_OTTOBRE MOVE TABLESPACE SMALL_DATA;
ALTER TABLE MYPERSON MOVE TABLESPACE LARGE_DATA;
ALTER TABLE PERSON MOVE TABLESPACE LARGE_DATA;
ALTER TABLE PERSON MOVE TABLESPACE LARGE_DATA;
ALTER TABLE PHONE MOVE TABLESPACE SMALL_DATA;
ALTER TABLE PIPPO MOVE TABLESPACE SMALL_DATA;
ALTER TABLE PLAN_TABLE MOVE TABLESPACE SMALL_DATA;
ALTER TABLE SCRAMBLE_TABLE MOVE TABLESPACE SMALL_DATA;
20 rows selected.
You see... table person is written twice...
so i do....
select 'ALTER TABLE ' || ds.segment_name || ' MOVE TABLESPACE ' ||
case when dt.blocks*v.value <= 5242880 then 'SMALL_DATA'
else 'LARGE_DATA'
end || ';'
from dba_segments ds, dba_tables dt, v$parameter v
where 1=1
and v.name='db_block_size'
and ds.segment_type = 'TABLE'
and ds.owner = 'GHADDART'
and ds.owner = dt.owner
and ds.segment_name = dt.table_name
and DS.TABLESPACE_NAME = DT.TABLESPACE_NAME
and (dt.blocks*v.value) IS not NULL;
And i get this error:
and (dt.blocks*v.value) IS not NULL
ERROR at line 13:
ORA-01722: invalid number
But up it was working !!!!
If i rerun it just not using the V$parameter but directly
the value it works:
select 'ALTER TABLE ' || ds.segment_name || ' MOVE TABLESPACE ' ||
case when dt.blocks*8192 <= 5242880 then 'SMALL_FOS_DATA'
else 'LARGE_FOS_DATA'
end || ';'
from dba_segments ds, dba_tables dt
where 1=1
--and v.name='db_block_size'
and ds.segment_type = 'TABLE'
and ds.owner = 'GHADDART'
and ds.owner = dt.owner
and ds.segment_name = dt.table_name
and DS.TABLESPACE_NAME = DT.TABLESPACE_NAME
and (dt.blocks*8192) IS not NULL;
And output now is right!!!
ALTER TABLE CHFL_20030922 MOVE TABLESPACE SMALL_FOS_DATA;
ALTER TABLE COFL_20031017 MOVE TABLESPACE SMALL_FOS_DATA;
ALTER TABLE COFL_20030922 MOVE TABLESPACE SMALL_FOS_DATA;
ALTER TABLE DM_PERS MOVE TABLESPACE LARGE_FOS_DATA;
ALTER TABLE AC_ACCOUNTS MOVE TABLESPACE LARGE_FOS_DATA;
ALTER TABLE AC_JOINTACC MOVE TABLESPACE LARGE_FOS_DATA;
ALTER TABLE ACTCIFNOMECOGNOME MOVE TABLESPACE LARGE_FOS_DATA;
ALTER TABLE ACTCIFCOGNOMENOME MOVE TABLESPACE LARGE_FOS_DATA;
ALTER TABLE ACTCIFNOME_COGNOME MOVE TABLESPACE LARGE_FOS_DATA;
ALTER TABLE PIPPO MOVE TABLESPACE SMALL_FOS_DATA;
ALTER TABLE PHONE MOVE TABLESPACE SMALL_FOS_DATA;
ALTER TABLE SCRAMBLE_TABLE MOVE TABLESPACE SMALL_FOS_DATA;
ALTER TABLE PERSON MOVE TABLESPACE LARGE_FOS_DATA;
ALTER TABLE MYPERSON MOVE TABLESPACE LARGE_FOS_DATA;
ALTER TABLE LISTA_SITO_OTTOBRE MOVE TABLESPACE SMALL_FOS_DATA;
ALTER TABLE CHANGES_FREEZE_LIST_20031017 MOVE TABLESPACE SMALL_FOS_DATA;
ALTER TABLE CHANGES_FREEZE_LIST_20030922 MOVE TABLESPACE SMALL_FOS_DATA;
ALTER TABLE CHFL_20031017 MOVE TABLESPACE SMALL_FOS_DATA;
ALTER TABLE PLAN_TABLE MOVE TABLESPACE SMALL_FOS_DATA;
19 rows selected.
WHY??? WHAT'S THE PROBLEM??
Thanks
