【问题描述】:
我正在尝试创建一个名为 add_extra 的函数。
CREATE OR REPLACE FUNCTION add_extra(p_price NUMBER)
RETURN NUMBER
IS
BEGIN
RETURN(9000);
END add_extra;
但是,当我运行脚本时,它会说:
Error starting at line 1 in command:
CREATE OR REPLACE FUNCTION add_extra(p_price NUMBER)
RETURN NUMBER
IS
BEGIN
RETURN(9000);
END add_extra;
Error report:
ORA-00955: name is already used by an existing object
00955. 00000 - "name is already used by an existing object"
*Cause:
*Action:
当我尝试时:DROP FUNCTION add_extra; 它告诉我:
Error starting at line 1 in command:
DROP FUNCTION add_extra
Error report:
SQL Error: ORA-04043: object ADD_EXTRA does not exist
04043. 00000 - "object %s does not exist"
*Cause: An object name was specified that was not recognized by the system.
There are several possible causes:
- An invalid name for a table, view, sequence, procedure, function,
package, or package body was entered. Since the system could not
recognize the invalid name, it responded with the message that the
named object does not exist.
- An attempt was made to rename an index or a cluster, or some
other object that cannot be renamed.
*Action: Check the spelling of the named object and rerun the code. (Valid
names of tables, views, functions, etc. can be listed by querying
the data dictionary.)
它存在还是不存在?我做错了什么?
【问题讨论】:
-
会不会是该功能存在但您无权查看?您是否尝试在您登录的架构中创建函数,或者您是否使用“alter session set current_schema ...”来处理不同的架构?您是否尝试过明确指定架构(CREATE OR REPLACE FUNCTION MYUSER.ADD_EXTRA...)?
-
我不确定,但我猜它在我登录的架构中,因为所有其他函数、过程等都出现在对象列表中。另外,当我使用 username.add_extra 时,我得到了同样的错误。
-
此查询可能有助于确定您的对象所在的架构 (
OWNER):SELECT * FROM ALL_OBJECTS WHERE OBJECT_NAME = 'ADD_EXTRA' -
感谢您的提示!它显示
DEGYVI09为所有者,但是当我尝试运行:DROP FUNCTION DEGYVI09.ADD_EXTRA时,它告诉我它不存在。
