Move multiple tables belonging to a particular schema

If you are running a number of schemas under one service -- which is usually the case -- and you need to move all the tables belonging to a particular schema to a new tablespace, then this script is for you. Instead of manually typing the command...

 Alter table tablename move tablespace tsname;

...for each individual table, use this simple procedure that uses the DBA_TABLES information to move all the tables belonging to a particular schema from one tablespace to another tablespace. It needs the SCHEMA NAME and the TABLESPACE NAME to be moved as input parameters.

CREATE OR REPLACE PROCEDURE   TOBJECTFROMTS ( 
   V_Owner     IN       VARCHAR2, 
   V_NEWTS     IN       VARCHAR2 

) 
IS 

  v_table_name   varchar2(100); 
  str_sql        varchar2(200); 

---Opening an explicit cursor to get all the users belonging 
---to the schema 
cursor schematables(Owner varchar2) is 
select TABLE_NAME   from DBA_TABLES x 
Where LOWER(x.OWNER) = LOWER(V_OWNER); 
BEGIN 
open schematables(V_owner); 

loop 
Fetch schematables into v_table_name ; 
          exit when schematables%notfound; 
        ---DBMS_OUTPUT.put_line(' alter table '|| v_table_name || ' move tablespace psle1;'); 
        str_sql := 'alter table '|| v_table_name || ' move tablespace' ||' ' ||'' || V_NEWTS ||''; 

        DBMS_OUTPUT.put_line(str_sql); 
        --- str_sql is the sql statement that we want to execute to move the 
        -- tablespaces to the new
