Question

我正在尝试从表中创建MS SQL服务器中的视图。表名是Account_Plan，我试图创建一个Account_Plan_vw视图。在执行DDL创建视图时，我收到错误，如下所示。

Msg 258，Level 15，State 1，Procedure Account_Plan_vw，Line 56
  无法在ntext上调用方法

Msg 207，Level 16，State 1，Procedure Account_Plan_vw，Line 22
  列名称“How_the_CU_will_achieve_these_objective2__c”无效。

错误消息显示“How_the_CU_will_achieve_these_objective2__c”列无效。但是，这是ntext类型的Account_Plan表中的有效列。

有人可以帮忙吗？我刚刚从Create视图语句中删除了多余的列。

CREATE VIEW [dbo].[Account_Plan_vw]
AS
SELECT   
 Results_1.Account__c
,Results_1.How_the_CU_will_achieve_these_objectives__c
,Results_1.How_the_CU_will_achieve_these_objective2__c
FROM 
(
  SELECT ROW_NUMBER() OVER (PARTITION BY apc1.Account__c ORDER BY apc1.Year__c DESC, apc1.CreatedDate DESC) AS RN_1
    ,apc1.Account__c
,apc1.How_the_CU_will_achieve_these_objectives__c
,apc1.How_the_CU_will_achieve_these_objective2__c
  FROM Account_Plan apc1
  INNER JOIN RecordType rtp1
  ON apc1.RecordTypeId=rtp1.[Id]
  AND rtp1.DeveloperName = 'Account_Plan' 
  INNER JOIN Account acc1
  ON acc1.[Id] = apc1.Account__c
  WHERE apc1.Year__c <= YEAR(GETDATE())
  ) AS Results_1
  WHERE RN_1 = 1

Answer 1

不推荐使用NTEXT，而是将其转换为NVARCHAR（MAX）

请参阅：ntext, text, and image (Transact-SQL)

您应该考虑更改表格，而不仅仅是在视图中投射，而是：

CREATE VIEW [dbo].[Account_Plan_vw]
AS
SELECT
      results_1.Account__c
    , results_1.How_the_CU_will_achieve_these_objectives__c
    , results_1.How_the_CU_will_achieve_these_objective2__c
FROM (
      SELECT
            ROW_NUMBER() OVER (PARTITION BY apc1.Account__c ORDER BY apc1.Year__c DESC, apc1.CreatedDate DESC) AS rn_1
          , apc1.Account__c
          , apc1.How_the_CU_will_achieve_these_objectives__c
          , cast(apc1.How_the_CU_will_achieve_these_objective2__c as nvarchar(max)) as How_the_CU_will_achieve_these_objective2__c
      FROM Account_Plan apc1
      INNER JOIN RecordType rtp1 ON apc1.RecordTypeId = rtp1.[Id]
            AND rtp1.DeveloperName = 'Account_Plan'
      INNER JOIN Account acc1 ON acc1.[Id] = apc1.Account__c
      WHERE apc1.Year__c <= YEAR(GETDATE())
) AS results_1
WHERE RN_1 = 1

Answer 2

问题，找到它有点神秘。 salesforce对象有一个字段last_peer_review_date__c，没有权限给任何人。因此，当我使用SF_Replicate命令时，DBAMP用户无法看到该字段，因此错过了在SQL Server中创建此字段。创建视图SQL是我几周前创建的，当时它确实有效。现在，当我使用相同的SQL时，它失败了，因为SQL有last_peer_review_date字段，但Account_Plan表没有。
