script-move a list of indexes - particular set of tables in a tablespace

[diwakar]

Dear All,

the script that I have given below gives me a list of indexes that are there for the corresponding tables in the tablespace P1ECP1_LT96K_D. Now having got the list of indexes I would like to move the indexes to another tablespace. Can anyone modify this script so that I will be getting the script for moving the indexes to a seperate tablespace as well.

Regards,

K.Diwakar


select
'select index_name from dba_indexes where table_name=''' ||table_name|| ''';'
from dba_tables where tablespace_name='P1ECP1_LT96K_D' and owner='DIP_S01' ;

H'mmm. I suspect you didn't try hard to solve this yourself, but anyway ...

select
   'Alter index '||owner||'.'||index_name||' rebuild tablespace my_tablespace;'
from
   dba_indexes
where
   (owner,table_name) in 
      (
      select
         owner,table_name
      from
         dba_tables
      where
         tablespace_name = 'P1ECP1_LT96K_D' and
         owner = 'DIP_S01'
      )
/

Hi Slimdave,

I was just breaking my head in the next step (after what I had posted) but just got stuck on that. Your reply is helpfull to a great extent in solving the problem.

Could you point out the mistake/edit what I have given below if I have proceeded in the correct way:


select
'select
'alter index' ||index_name|| 'move tablespace P1ECP1_LT96K_X ;'
from dba_indexes where table_name='''||table_name||''';'
from dba_indexes where tablespace_name='P1ECP1_LT96K_D'
;


Thanks and Regards,

Most likely you are getting your single quote occurances incorrect. ie. to place a literal single quote in a string you have to ...

'beforequote''afterquote'

... and to nest another level inside that you have to ..

'beforenestedstring''insidenestedstring''''stillinside''notinnestedstring'

This is really because you are writing a SQL to generate a series of SQL's that then generate another series of SQL's -- the example i gave just "jumps" straight down to the lowest level in one go.

You can't MOVE indexes to another tablespace. You have to REBUILD indexes to move them!

Correct :
SELECT
'ALTER INDEX ' || index_name || ' REBUILD TABLESPACE P1ECP1_LT96K_X;'
FROM dba_indexes WHERE tablespace_name='P1ECP1_LT96K_D';
