Using Link DB to query Source DB and Insert results in Target DB

Question

Hi
I have created a link between the source database and target database.
I have a simple query that queries the dba_segments table in the source db
Using a cursor, I'd like to insert those records into a table in the target database. I believe this has to be done with a cursor.
Does anyone have the proper syntax for this type of operation that I could pick apart.
This is what I have so far:
DECLARE
Cursor GetTableSizesEmr IS select owner,segment_name,bytes as Bytes, bytes/1024/1024 as Megs,(blocks*8192)/1024 as totsize_block
from dba_segments@LINKNAME
where owner='KEN'
and tablespace_name ='MY_DATA';
BEGIN
open GetTableSizesEmr;
LOOP
FETCH GetTableSizesEmr Into TARGET_Table
EXIT WHEN c_emp%NOTFOUND;
END LOOP:
CLOSE GetTableSizesEmr;
END;
Thanks for any help.

Well, you think wrong.
SQL> SELECT * FROM t;
        ID DESCR
         1 ONE
         2 TWO
         3 THREE
         4 FOUR
SQL> SELECT * FROM t1;
        ID DESCR
         6 SIX
         7 SEVEN
         8 EIGHT
         9 NINE
SQL> INSERT INTO t
  2  SELECT * FROM t1;
4 rows created.
SQL> SELECT * FROM t;
        ID DESCR
         1 ONE
         2 TWO
         3 THREE
         4 FOUR
         6 SIX
         7 SEVEN
         8 EIGHT
         9 NINEThe presence of a db_link makes no difference to the basic structure.
