BizTalk WCF-SQL适配器从视图中选择

我有一个最烦人的问题;

我有一个业务流程对视图进行查找。 它适用于本地和我们的开发服务器，但不适用于QA或UAT。 相同的代码。相同的观点。只是不同的环境。

为了测试这一点并确保它不是编码问题，我采用我的本地BizTalk，将端口配置为服务器A，触发消息并按预期工作。 然后我将发送端口的配置更改为服务器B（这就是我所有的更改）并触发相同的消息，然后失败。

我为SAME视图的相同操作收到两个错误之一，所以即使错误消息也不一致。

我要求<Columns>*</Columns>和<Query>WHERE FIELD='xyz'</Query>

这是实际的消息; 

<ns0:Select xmlns:ns3="http://schemas.microsoft.com/Sql/2008/05/Types/Views/dbo" xmlns:ns0="http://schemas.microsoft.com/Sql/2008/05/ViewOp/dbo/CRM_CUST">
<ns0:Columns>*</ns0:Columns>
<ns0:Query>WHERE ACCOUNTNUM='id_0'</ns0:Query>
</ns0:Select>

然后我有一个带有sqlbinding的TwoWay Wcf-Custom Send端口。这是配置

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.serviceModel>
    <client>
      <endpoint address="mssql://devserver//DbName?" behaviorConfiguration="EndpointBehavior" binding="sqlBinding" bindingConfiguration="sqlBinding" contract="BizTalk" name="CUST Lookup" />
    </client>
    <behaviors>
      <endpointBehaviors>
        <behavior name="EndpointBehavior" />
      </endpointBehaviors>
    </behaviors>
    <bindings>
      <sqlBinding>
        <binding name="sqlBinding" useAmbientTransaction="false" />
      </sqlBinding>
    </bindings>
  </system.serviceModel>
</configuration>

动作映射中的此设置;

ViewOp/Select/dbo/CRM_CUST - 视图名称

因此;放弃了从视图中选择操作应该很简单并且怀疑适配器的这个特定部分的代码存在问题我决定尝试“技巧”。

我创建了一个存储过程，只执行SELECT * FROM VIEW WHERE ID = @Param（导致问题的相同视图），其中Param是我传入ViewOp条件的AccountNum

然后使用适配器向导为TypeStoredProcedure操作而不是ViewOp生成模式 更改了地图以生成此新消息 Redploy 并且presto ...我现在可以愉快地在两个环境之间切换而没有任何错误！

这清楚地告诉我，SQL适配器的ViewOp部分存在问题！？！？ 除了适配器的问题之外，还有任何其他想法/解释为什么会发生这种情况吗？

我知道大多数人都说不使用视图而是转到存储过程，但我们使用视图的原因非常充分。我们正在针对Microsoft Dynamics AX数据库进行选择。 AX发布这些视图以供外部系统使用。 Microsoft不支持针对AX架构创建存储过程，因为它会更改其数据库。如果我们使用CRM上的视图，我们也无法随意创建存储过程。

所以我现在可以使用的解决方案，但它不受支持。 它必须暂时停留，直到我们解决这个问题

我最近遇到了同样的问题。花了一天后，我终于启动了一个SQL Profiler并找到了原因。由于某些DB（包括Ax2009 DB）的某些原因，biztalk想要的视图和列顺序中列出的列顺序存在差异。它执行以下代码并希望列完全按顺序排列（'*'对您不起作用）：

exec sp_executesql N'SELECT sp.type AS [ObjectType], modify_date AS [LastModified] FROM sys.all_objects AS sp WHERE (sp.name=@ORIGINALOBJECTNAME and SCHEMA_NAME(sp.schema_id)=@ORIGINALSCHEMANAME);SELECT clmns.name AS [Name], usrt.name AS [DataType], SCHEMA_NAME(usrt.schema_id) AS DataTypeSchemaName, usrt.is_assembly_type AS [IsAssemblyType], clmns.is_identity AS [IsIdentity], ISNULL(baset.name, N'''') AS [SystemType], CAST(CASE WHEN baset.name IN (N''nchar'', N''nvarchar'') AND clmns.max_length <> -1 THEN clmns.max_length/2 ELSE clmns.max_length END AS int) AS [Length], CAST(clmns.[precision] AS int) AS [NumericPrecision], CAST(clmns.[scale] AS int) AS [NumericScale], clmns.is_nullable as [IsNullable], clmns.is_computed as [IsComputed], 0 as [IsFileStream], AT.assembly_qualified_name AS AssemblyQualifiedName, defCst.definition AS [DefaultValue] FROM sys.columns as clmns LEFT OUTER JOIN sys.default_constraints defCst on defCst.parent_object_id = clmns.object_id and defCst.parent_column_id = clmns.column_id LEFT OUTER JOIN sys.types AS usrt ON usrt.user_type_id = clmns.user_type_id LEFT OUTER JOIN sys.types AS baset ON baset.user_type_id = clmns.system_type_id and baset.user_type_id = baset.system_type_id LEFT JOIN sys.assembly_types AT ON AT.[name] = usrt.name AND AT.schema_id = usrt.schema_id WHERE clmns.object_id = (SELECT object_id FROM sys.objects o WHERE o.name=@ORIGINALOBJECTNAME and SCHEMA_NAME(o.schema_id)=@ORIGINALSCHEMANAME)',N'@ORIGINALOBJECTNAME nvarchar(13),@ORIGINALSCHEMANAME nvarchar(3)',@ORIGINALOBJECTNAME=N'CRM_CFU',@ORIGINALSCHEMANAME=N'dbo'

只需将@ORIGINALOBJECTNAME值替换为您的视图名称，然后按照确切的顺序在您的选择中添加列。
