Hi I ahve tried your commmand but it is giving following error.
Error report:
ORA-00942: table or view does not exist
ORA-06512: at line 3
00942. 00000 - "table or view does not exist"Then you're doing something wrong. In which case you need to instrument the code to give you step-by-step feedback. For example:
begin
  for t in (select table_name from user_tables where table_name like 'C$%' ) loop
    begin
        dbms_output.put_line( 'Dropping table '||t.table_name );
        execute immediate 'drop table '||t.table_name;
        dbms_output.put_line( 'Table dropped' );
    exception when others then
        dbms_output.put_line( 'Table drop failed with '||SqlErrM(SqlCode) );
    end;
  end loop;
end;If the table names are case sensitive or contains special characters, you need to wrap the table name in double quotes in the drop table statement.
PS. Keep in mind that simply dropping tables like this is VERY unusual. Make sure you are doing the right thing and addressing the problem (which you neglected to mention), correctly. You could be digging a deep and dark hole for yourself by dropping tables, and the wrong ones, like this.
