根据错误信息，可以看出问题出在 UPDATE 语句中的 `DBMS_CRYPTO.ENCRYPT` 函数上，因为它需要的参数类型与 `PRICE` 的数据类型不一致。

这是因为 `TO_CHAR` 函数将 `PRICE` 转换为文本字符串，而 `DBMS_CRYPTO.ENCRYPT` 函数需要的是二进制数据。为了解决这个问题，我们可以在 `TO_CHAR` 函数之前使用 `CAST` 函数将 `PRICE` 转换为二进制数据类型 `RAW`，然后再将其转换为文本字符串。

修改后的代码如下：

CREATE OR REPLACE PROCEDURE ENCRYPT_PRICE AS
  C_KEY VARCHAR2(32) := 'MY_SECRET_KEY_FOR_AES256';
BEGIN
  UPDATE PRODUCT SET PRICE = DBMS_CRYPTO.ENCRYPT(
    UTL_I18N.STRING_TO_RAW(CAST(PRICE AS RAW), 'AL32UTF8'),
    DBMS_CRYPTO.ENCRYPT_AES256 + DBMS_CRYPTO.CHAIN_CBC + DBMS_CRYPTO.PAD_PKCS5,
    UTL_I18N.STRING_TO_RAW(C_KEY, 'AL32UTF8'),
    NULL
  ) WHERE PRICE IS NOT NULL;
END;

根据错误信息，可以看出问题出在 `DBMS_CRYPTO.CHAIN_IV` 上，因为该标识符无效。实际上，DBMS_CRYPTO 包中没有 `CHAIN_IV` 这个组件，所以需要将其替换为 `NULL`。

修改后的代码如下：

CREATE OR REPLACE PROCEDURE ENCRYPT_PRICE AS
  C_KEY VARCHAR2(32) := 'MY_SECRET_KEY_FOR_AES256';
BEGIN
  UPDATE PRODUCT SET PRICE = DBMS_CRYPTO.ENCRYPT(
    UTL_I18N.STRING_TO_RAW(TO_CHAR(PRICE), 'AL32UTF8'),
    DBMS_CRYPTO.ENCRYPT_AES256 + DBMS_CRYPTO.CHAIN_CBC + DBMS_CRYPTO.PAD_PKCS5,
    UTL_I18N.STRING_TO_RAW(C_KEY, 'AL32UTF8'),
    NULL
  ) WHERE PRICE IS NOT NULL;

根据错误信息，可以看出问题出在 `UPDATE` 语句中的 `DBMS_CRYPTO.ENCRYPT` 函数上，因为缺少左括号。这可能是因为 `DBMS_CRYPTO.ENCRYPT_AES256`、`DBMS_CRYPTO.CHAIN_CBC` 和 `DBMS_CRYPTO.PAD_PKCS5` 这三个常量之间应该使用竖线 `|` 进行位运算符的 OR 运算，而不是加号 `+`。

修改后的代码如下：

CREATE OR REPLACE PROCEDURE ENCRYPT_PRICE AS
  C_KEY VARCHAR2(32) := 'MY_SECRET_KEY_FOR_AES256';
BEGIN
  UPDATE PRODUCT SET PRICE = DBMS_CRYPTO.ENCRYPT(
    UTL_I18N.STRING_TO_RAW(CAST(PRICE AS RAW), 'AL32UTF8'),
    DBMS_CRYPTO.ENCRYPT_AES256 | DBMS_CRYPTO.CHAIN_CBC | DBMS_CRYPTO.PAD_PKCS5,
    UTL_I18N.STRING_TO_RAW(C_KEY, 'AL32UTF8'),
    NULL
  ) WHERE PRICE IS NOT NULL;
END;
