Question

I want to drop certain tables in a tablespace that has common name appended to end of each table for an example:

TABLE1_NAME1_COMMON
TABLE2_NAME2_COMMON
TABLE3_NAME3_COMMON

I heard about Oracle functions but I’m not familiar much with those so I’m expecting some helping hand.

Thanks.

Answer 1

If you’re completely sure what you’re doing, ie, if you’re sure that you don’t accidentally drop a table that you don’t want to drop, you can do a:

set serveroutput on size 1000000

begin
for r in (

  select table_name 
    from user_tables 
   where table_name like '%\_COMMON' escape '\')

loop

  execute immediate 'drop table ' || r.table_name;

end loop;
exception when others then
   dbms_output.put_line(sqlerrm);
end;
/

Edit:

1. Changed Now selecting from user_tables instead of dba_tables as it seems more safe to do.
2. Added set serveroutput on in order for dbms_output.put_line to be printed
3. Added begin .. exception .. end in order for errors to be shown.
