錯誤（4,1）：PLS-00103：遇到符號「AS」

Question

我想創建和編譯以下函數有什麼問題？

我得到這個錯誤代碼，我不確定它到底出了什麼問題。

Error(4,1): PLS-00103: Encountered the symbol "AS" when expecting one of the following:  return 

代碼：

create or replace FUNCTION BOD_FM_FSCS_A_Data(
    -- Add the parameters for the function here 
    p_ExclusionsOnly NUMBER DEFAULT 0) 
AS 
IS 
BEGIN 
    INSERT INTO @ATable 
    SELECT DISTINCT SCVID, 
    Title, 
    Forename1, 
    Forename2, 
    Forename3, 
    CASE 
     WHEN CompanyName IS NULL 
     OR CompanyName ='' 
     THEN Surname 
     ELSE CompanyName 
    END AS Surname , 
    PreviousName, 
    NI_No, 
    PassportNo, 
    OtherNational_ID, 
    OtherNational_ID_No , 
    CompanyNo, 
    DateOfBirth 
    FROM DIM_FM_FSCS_Customer customer 
    INNER JOIN DIM_FM_FSCS_CustomerAccLink cal 
    ON cal.FSCSCustomerLink=customer.ID 
    INNER JOIN DIM_FM_FSCS_Account acc 
    ON acc.ID    =cal.FSCSAccountLink 
    AND ((p_ExclusionsOnly=1 
    AND acc.ExclusionCode <>'') 
    OR (p_ExclusionsOnly =0 
    AND acc.ExclusionCode = '')); 
    RETURN 
END; 

Answer 1

錯誤本身就說明：

錯誤（4,1）：PLS-00103：出現符號 「AS」 的期待時，一個 如下：return

刪除AS並定義什麼是func重刑RETURN

create or replace FUNCTION BOD_FM_FSCS_A_Data(
    -- Add the parameters for the function here 
    p_ExclusionsOnly NUMBER DEFAULT 0) 
RETURN NUMBER.... 

下面是來自docs

CREATE FUNCTION get_bal(acc_no IN NUMBER) 
    RETURN NUMBER 
    IS acc_bal NUMBER(11,2); 
    BEGIN 
     SELECT order_total 
     INTO acc_bal 
     FROM orders 
     WHERE customer_id = acc_no; 
     RETURN(acc_bal); 
    END;
