尽管获得了 GRANT EXECUTE，但我在函数调用中得到 "ORA-00904: invalid identifier"

Question

我正在尝试为 DSCRPT 用户名调用 IS_NUMBER 函数，但我必须在 DSCDBA 登录中创建该函数我授予了 EXECUTE 权限，就像我对其他多个功能一样，但是这个会引发 INVALID IDENTIFIER 错误

函数：

create or replace 
FUNCTION is_number (p_string IN VARCHAR2)
   RETURN INT
IS
   v_new_num NUMBER;
BEGIN
   v_new_num := TO_NUMBER(p_string);
   RETURN 1;
EXCEPTION
WHEN VALUE_ERROR THEN
   RETURN 0;
END;

授予：

GRANT EXECUTE ON "DCSDBA"."IS_NUMBER" TO "DCSRPT";

以 DSCRPT

身份登录时执行 SQL

SELECT IS_NUMBER('123') FROM DUAL;

错误：

ORA-00904: "IS_NUMBER": invalid identifier 00904. 00000 - "%s: invalid identifier" *Cause:
*Action: Error at Line: 1 Column: 8

已确认我可以在登录 DSCRPT 时看到该功能

SELECT * FROM ALL_OBJECTS WHERE OBJECT_TYPE IN ('FUNCTION') and owner = 'DCSDBA' order by owner, object_name;

Return of ALL_OBJECTS search

Answer 1

尝试拨打电话

SELECT DCSDBA.IS_NUMBER('123') FROM DUAL;

尽管获得了 GRANT EXECUTE，但我在函数调用中得到 "ORA-00904: invalid identifier"

I get "ORA-00904: invalid identifier" on function call despite being given GRANT EXECUTE

sql

oracle

function

ora-00904
