【问题描述】：

我已经在一个包中创建了程序...在 TOAD 中编译时，没有错误，但在提交我的 jsp 页面后它显示

""包体 "USERINFO.FORM_PKG" 有错误 ORA-06508: PL/SQL: could 找不到被调用的程序单元：“USERINFO.FORM_PKG”“”

CREATE OR REPLACE PACKAGE form_pkg AS  -- package body
PROCEDURE Insert_receipts(
p_receipt NUMBER, 
p_transaction NUMBER, 
p_amount NUMBER);
PROCEDURE Insert_stkqntys(
p_itemid NUMBER, 
p_date VARCHAR2,
p_supplier VARCHAR2,
p_type VARCHAR2,
p_transaction NUMBER,
p_quantity NUMBER);
END form_pkg;
/
CREATE OR REPLACE PACKAGE BODY form_pkg AS  -- package body

PROCEDURE Insert_receipts (

 p_receipt NUMBER(6), 
 p_transaction NUMBER(5), 
 p_amount NUMBER(10),
 seq_value  NUMBER) IS
 BEGIN

 INSERT INTO receipt
 ( ID, Receipt_Number,Transaction_ID,Amount) 
  VALUES (seq.nextval, p_receipt, p_transaction, p_amount); 
END Insert_receipts
;
PROCEDURE Insert_stkqntys

 END Insert_stkqntys;
 End form_pkg;

【问题讨论】：

请看详情：select * from user_errors where name = upper('form_pkg')
你不能定义参数的限制 - 删除字符的长度/数字的特异性。
我看到了不同的声明：PROCEDURE Insert_receipts(p_receipt NUMBER, 和 PROCEDURE Insert_receipts (p_receipt NUMBER(6) - 请注意6。包及其主体必须具有相同的过程/函数声明
是属于用户信息
在写入 select * from user_errors where name = upper('form_pkg') 后出现错误我收到错误为 PLS-00103：在预期以下情况之一时遇到符号“（”：：=。 ) , @ % 默认字符符号 ":=" 被替换为 "(" 以继续。在行号 5,6,7,18,19,20,21,22

【解决方案1】：

过程'/函数'声明在package 和它的body 中必须相同。尽量避免幻数比如p_amount NUMBER(10)：10是什么意思？但是使用p_amount receipt.Amount%Type 这很清楚 receipt.Amount 字段的类型。

CREATE OR REPLACE PACKAGE form_pkg AS  
  -- interface: procedure with 3 arguments
  PROCEDURE Insert_receipts(
    p_receipt     receipt.Receipt_Number%Type, 
    p_transaction receipt.Transaction_ID%Type, 
    p_amount      receipt.Amount%Type);

  ...
END form_pkg;
/

CREATE OR REPLACE PACKAGE BODY form_pkg AS  -- package body
  -- implementation
  -- The same three arguments (no seq_value!)
  PROCEDURE Insert_receipts (
    p_receipt     receipt.Receipt_Number%Type, 
    p_transaction receipt.Transaction_ID%Type, 
    p_amount      receipt.Amount%Type) 
  IS
  BEGIN
    INSERT INTO receipt( 
      ID, 
      Receipt_Number,
      Transaction_ID,
      Amount) 
    VALUES (
      seq.NextVal, 
      p_receipt, 
      p_transaction, 
      p_amount);
  END Insert_receipts;

  ...
END form_pkg;
/

在实施例程时，您可以在 USER_ERRORS 视图中查看错误的详细信息（名称、行等）：

-- all (syntactic) errors in the form_pkg
select *
  from USER_ERRORS
 where Name = upper('form_pkg')

【解决方案2】：

包规范和主体应该对每个过程/函数具有相同的参数/数据类型，并且不能包含大小/比例/精度。

另外，使用[SCHEMA_NAME.]TABLE_NAME.COLUMN_NAME%TYPE 而不是显式声明类型。但是，如果您要使用基础数据类型，则只需删除精度。 IE。 p_receipt NUMBER(6) 应该只是 p_receipt NUMBER 没有大小/比例/精度。

CREATE OR REPLACE PACKAGE form_pkg AS  -- package specification
  PROCEDURE Insert_receipts(
    p_receipt     RECEIPT.RECEIPT_NUMBER%TYPE, 
    p_transaction RECEIPT.TRANSACTION_ID%TYPE, 
    p_amount      RECEIPT.AMOUNT%TYPE
  );

  PROCEDURE Insert_stkqntys(
    p_itemid      STOCK_QUANTITY.ITEM_ID%TYPE, 
    p_date        STOCK_QUANTITY.DATE_RECEIVED%TYPE,
    p_supplier    STOCK_QUANTITY.SUPPLIER_CHALLAN%TYPE,
    p_type        STOCK_QUANTITY.TRANSACTION_TYPE%TYPE,
    p_transaction STOCK_QUANTITY.TRANSACTION_ID%TYPE,
    p_quantity    STOCK_QUANTITY.QUANTITY%TYPE
  );
END form_pkg;
/

CREATE OR REPLACE PACKAGE BODY form_pkg AS  -- package body
  PROCEDURE Insert_receipts (
    p_receipt     RECEIPT.RECEIPT_NUMBER%TYPE, 
    p_transaction RECEIPT.TRANSACTION_ID%TYPE, 
    p_amount      RECEIPT.AMOUNT%TYPE
  )
  IS
  BEGIN
    INSERT INTO receipt (
      ID,
      Receipt_Number,
      Transaction_ID,
      Amount
    ) VALUES (
      seq.nextval, 
      p_receipt, 
      p_transaction, 
      p_amount
    ); 
  END Insert_receipts;

  PROCEDURE Insert_stkqntys 
  (
    p_itemid      STOCK_QUANTITY.ITEM_ID%TYPE, 
    p_date        STOCK_QUANTITY.DATE_RECEIVED%TYPE,
    p_supplier    STOCK_QUANTITY.SUPPLIER_CHALLAN%TYPE,
    p_type        STOCK_QUANTITY.TRANSACTION_TYPE%TYPE,
    p_transaction STOCK_QUANTITY.TRANSACTION_ID%TYPE,
    p_quantity    STOCK_QUANTITY.QUANTITY%TYPE
  )
  IS
  BEGIN
    INSERT INTO stock_quantity(
      ID,
      Item_ID,
      Date_Received,
      Supplier_Challan,
      Transaction_Type,
      Transaction_ID,
