从Shell脚本调用的sqlplus

Question

I have a problem calling SQL commands directly from a shell script. My shell script contains the following commands:

set x = `sqlplus -S $ISLK_ORACLE_UID` <<EOF

delete from rc where rcd_id = 1 ;
update rcd set standard = 'Test_DB7' where id = 1 ;
delete from rc where rcd_id = 2 ;
update rcd set standard = '700' where id = 2 ;
delete from rc where rcd_id = 5 ;
update rcd set standard = 'DB7' where id = 5 ;
delete from rc where rcd_id = 998 ;
update rcd set standard = '2001-2050' where id = 998 ;

delete from rc where rcd_id=3004 ;

begin
for fd_rec in (select * from fd)
loop
   insert into rc values(1008, 1, fd_rec.id, 'islk.am@swisscom.com') ;
end loop ;
end ;

commit;

EOF

The single commands (delete, update) are completed without any problems, but thw loop seems not to be performed (nothing inserted after statement). Has anybody an idea what the problem might be?

Thanks a lot in advance Best wishes Jörg

Answer 1

You could rewrite your loop with a single SQL statement:

insert into rc select 1008, 1, id, 'islk.am@swisscom.com' from fd;

This is (to me) more readable and more efficient, given that it uses no PL/SQL and loops, but simply relies on pure SQL.
