函數創建時編譯錯誤成功，爲什麼？

Question

我試圖在Oracle Apex 5 SQL命令中創建這個函數，並導致了這個錯誤'ORA-24344：編譯錯誤成功'。你爲什麼這麼認爲？我試圖創建一個隨機生成的代碼。

CREATE OR REPLACE FUNCTION generate_code() 
    return varchar2 
    AS 
    code varchar2; 
    BEGIN 
    code := DBMS_RANDOM.value(1,100); 
    return code; 
    END; 

Answer 1

錯誤的語法，請參見下面

正確的語法是

CREATE OR REPLACE FUNCTION generate_code 

    return varchar2 
    AS 
    code varchar2(100); 
    BEGIN 
    code := DBMS_RANDOM.value(1,100); 
    return code; 
    END; 

原始語法錯誤描述：

SQL> CREATE OR REPLACE FUNCTION generate_code() 
    2 
    3  return varchar2 
    4  AS 
    5  code varchar2; 
    6  BEGIN 
    7  code := DBMS_RANDOM.value(1,100); 
    8  return code; 
    9  END; 
10
