不编译无效的包体。有人知道原因吗?
(Oracle 数据库 11g 企业版 11.2.0.1.0 版 - 生产)
最佳答案
确实如此;至少在 11.2.0.3 中,所以我想基本版本中可能存在错误。
如果我创建了一个无效的包,在这种情况下是因为它引用了一个不存在的表:
create package p42 as
procedure test;
end p42;
/
PACKAGE P42 compiled
create package body p42 as
procedure test is
n number;
begin
select count(*) into n from t42;
end test;
end p42;
/
PACKAGE BODY P42 compiled
Errors: check compiler log
然后检查状态和上次 DDL 时间:
select object_type, object_name, status, last_ddl_time
from user_objects where object_name = 'P42'
order by object_type, object_name;
OBJECT_TYPE OBJECT_NAME STATUS LAST_DDL_TIME
------------------- -------------------- ------- -------------------
PACKAGE P42 VALID 2015-03-02 17:39:42
PACKAGE BODY P42 INVALID 2015-03-02 17:39:42
然后重新编译架构并再次检查:
BEGIN
DBMS_UTILITY.COMPILE_SCHEMA(schema => USER, compile_all => FALSE);
END;
/
anonymous block completed
select object_type, object_name, status, last_ddl_time
from user_objects where object_name = 'P42'
order by object_type, object_name;
OBJECT_TYPE OBJECT_NAME STATUS LAST_DDL_TIME
------------------- -------------------- ------- -------------------
PACKAGE P42 VALID 2015-03-02 17:39:42
PACKAGE BODY P42 INVALID 2015-03-02 17:39:49
..上次DDL时间变了,所以重新编译了。它仍然无效,因为我还没有解决根本问题。我可以看到
select text from user_errors where name = 'P42';
TEXT
------------------------------------------------------------
PL/SQL: ORA-00942: table or view does not exist
PL/SQL: SQL Statement ignored
或者,如果您的
'<SCHEMA_NAME>'
不是您当前的用户,则它将在 all_errors
中,如果它仍然无效。如果我创建丢失的表并再次编译架构:
create table t42 (id number);
Table t42 created.
BEGIN
DBMS_UTILITY.COMPILE_SCHEMA(schema => USER, compile_all => FALSE);
END;
/
anonymous block completed
select object_type, object_name, status, last_ddl_time
from user_objects where object_name = 'P42'
order by object_type, object_name;
OBJECT_TYPE OBJECT_NAME STATUS LAST_DDL_TIME
------------------- -------------------- ------- -------------------
PACKAGE P42 VALID 2015-03-02 17:39:42
PACKAGE BODY P42 VALID 2015-03-02 17:40:11
... 上次 DDL 时间又发生了变化,现在的状态也是如此。如果我使用您的
compile_all => FALSE
标志再次编译,那么最后的 DDL 时间不会改变,因为它不会查看有效的包。关于oracle - DBMS_UTILITY.COMPILE_SCHEMA(schema => '<SCHEMA_NAME>' , compile_all => FALSE) 不编译无效的包体,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/28815914/
