从shell脚本调用sqlplus

Question

我有一个直接从shell脚本调用SQL命令的问题。我的shell脚本包含以下命令：

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 

单命令（删除，更新）没有任何问题的完成，但THW循环似乎并没有被执行（没有语句后插入）。有谁知道这个问题可能是什么？

你可以用一个SQL语句改写你的循环：

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

这是（我）更易读，更高效，因为它不使用PL/SQL和循环，而仅仅依赖于纯SQL。
