delete from(
select 1
from cust_interest a, cust_basicinfo b
where a.cust_no = b.cust_no
and b.cust_status <> '0');
这个语句是删除cust_interest表中的数据,我就是不知道oracle怎么确定删除cust_interest表而不是cust_basicinfo表数据,
请大家指导一下,谢谢。

呵呵,不但是你不知道,连ORACLE也不太清楚吧。
这个语句执行的时候会报错。
SQL Error: ORA-01752: cannot delete from view without exactly one key-preserved table
01752. 00000 - "cannot delete from view without exactly one key-preserved table"
*Cause: The deleted table either had no key perserved tables,
had more than one key-preserved table, or the key-preserved
table was an unmerged view or a table from a read-only view.
*Action: Redefine the view or delete it from the underlying base tables.
