Oracle将自定义表类型传递给存储过程

Question

FYI: Oracle12c

我创建了一个名为Payeezy_Error的自定义类型

create or replace TYPE PAYEEZY_ERROR
AS

  OBJECT (
    CODE VARCHAR(30),
    DESCRIPTION VARCHAR(200)
  );

然后又创建了一个表类型的Payeezy_Errors

create or replace TYPE PAYEEZY_ERRORS AS TABLE OF PAYEEZY_ERROR;

然后，我有一个以Payeezy_Errors作为IN参数的过程：

create or replace PROCEDURE SAVE_USER_PAYMENT_TRANSACTION
(
  in_AccountID         IN VARCHAR2,
  in_SequenceID        IN VARCHAR2,
  in_CorrelationID     IN VARCHAR2,
  in_TransactionID     IN VARCHAR2,
  in_TransactionTag    IN VARCHAR2,
  in_Currency          IN VARCHAR2,
  in_TransactionType   IN VARCHAR2,
  in_BankResponse      IN VARCHAR2,
  in_GatewayResponse   IN VARCHAR2,
  in_ValidationStatus  IN VARCHAR2,
  in_TransactionStatus IN VARCHAR2,
  in_Errors            IN PAYEEZY_ERRORS
)
AS

  var_uptID NUMBER;
  var_ErrorCount NUMBER := 0;

  EX_AUTHENTICATION EXCEPTION;

BEGIN

  -- Insert the Payeezy Response values tied to the user
  INSERT INTO
    USER_PAYMENT_TRANSACTION (
      ACCOUNT_ID,         UP_PAYMENT_SEQ_ID,   CORRELATION_ID,       TRANSACTION_ID,
      TRANSACTION_TAG,    CURRENCY,            TRANSACTION_TYPE,     BANK_RESPONSE,
      GATEWAY_RESPONSE,   VALIDATION_STATUS,   TRANSACTION_STATUS
    ) VALUES (
      in_AccountID,       in_SequenceID,       in_CorrelationID,     in_TransactionID,
      in_TransactionTag,  in_Currency,         in_TransactionType,   in_BankResponse,
      in_GatewayResponse, in_ValidationStatus, in_TransactionStatus
    )
  RETURNING
    ID
  INTO
    var_uptID;

  -- Insert any errors that may be associated with a failure/unsuccessful transaction
  SELECT
    COUNT(*)
  INTO
    var_ErrorCount
  FROM
    in_Errors;

  IF (var_ErrorCount > 0) THEN
    INSERT INTO
      USER_PAYMENT_TRANSACTION_ERROR (
        UPT_ID, CODE, DESCRIPTION
      )
    SELECT
      var_uptID, e.CODE, e.DESCRIPTION
    FROM
      in_Errors;
  END IF;


  -- Exception Handling
  EXCEPTION
    WHEN EX_AUTHENTICATION THEN
      raise_application_error(-20001, 'Authentication Failed.');

END SAVE_USER_PAYMENT_TRANSACTION;

当我编译这个过程时，它对着SELECT COUNT(*)语句大喊大叫：

ORA-00942: table or view does not exist.

红色破折号在SELECT和in_Errors下面。

在下面的过程中，我得到了同样的错误，第二行INSERT INTO和in_Errors行也是红色破折号。

我已经退出并重新加载了Oracle SQL Developer，以查看它是否是缓存功能。我已经在网上搜索过了，但没有找到我的具体案例。

如果要在查询中使用表，则需要使用table运算符

SELECT
    COUNT(*)
  INTO
    var_ErrorCount
  FROM
    table( in_Errors );

这是可行的。但这意味着您将获取PL/SQL集合中的所有数据，将其移动到SQL，进行聚合，然后将结果返回给PL/SQL。在这种情况下，这样做可能会更有效率(而且代码更少)。

var_ErrorCount := in_Errors.count;
