oracle 10g pl/sql条件循环选择

Question

是否可以在PL/SQL 10g中做这样的事情？

if user_is_goat = 1 then 
    for item_rec in (select * from pricing_for_goats) 
else 
    for item_rec in (select * from pricing_for_non_goats) 
end if; 
loop 
. 
. 
end loop; 

看来，当Oracle看到“在选择REC *从双反”，预计“循环”，以立即采取后续。我在循环中的代码是很多行，我不想保存它的两个副本。

下面

尝试查询，这将检查是否从其他for_goats可变user_is_goat = 1并返回数据它将从for_non_goats

for item_rec in 
(
    select * from pricing_for_goats where user_is_goat = 1 
    union 
    select * from pricing_for_non_goats where user_is_goat <> 1 
) 
loop 
..... 
..... 
end loop;
