BizTalk - 使用表变量参数从 Oracle 存储过程生成模式
我正在尝试在 BizTalk 中设置一个简单的示例项目,该项目获取对 SQL Server 数据库中的表所做的更改并更新 Oracle 数据库中该表的副本。
在 SQL Server 端,我有一个名为 GetItemChanges() 的存储过程,它返回可变数量的记录。
在 Oracle 方面,我有一个名为 Update_Item_Region_Table() 的存储过程,旨在将记录表作为参数,以便它可以在一次调用中处理从 GetItemChanges() 返回的所有记录。它的定义如下:
create or replace type itemrec is OBJECT (
UPC VARCHAR2(15),
REGION VARCHAR2(5),
LONG_DESCRIPTION VARCHAR2(50),
POS_DESCRIPTION VARCHAR2(30),
POS_DEPT VARCHAR2(5),
ITEM_SIZE VARCHAR2(10),
ITEM_UOM VARCHAR2(5),
BRAND VARCHAR2(10),
ITEM_STATUS VARCHAR2(5),
TIME_STAMP VARCHAR2(20),
COSTEDBYWEIGHT INTEGER
);
create or replace type tbl_of_rec is table of itemrec;
create or replace PROCEDURE Update_Item_Region_table ( Item_Data tbl_of_rec )
IS
errcode integer;
errmsg varchar2(4000);
BEGIN
for recIndex in 1 .. Item_Data.COUNT
loop
update FL_ITEM_REGION_TEST set
Region = Item_Data(recIndex).Region,
Long_description = Item_Data(recIndex).Long_description,
Pos_Description = Item_Data(recIndex).Pos_description,
Pos_Dept = Item_Data(recIndex).Pos_dept,
Item_Size = Item_Data(recIndex).Item_Size,
Item_Uom = Item_Data(recIndex).Item_Uom,
Brand = Item_Data(recIndex).Brand,
Item_Status = Item_Data(recIndex).Item_Status,
Timestamp = to_date(Item_Data(recIndex).Time_stamp, 'yyyy-mm-dd HH24:mi:ss'),
CostedByWeight = Item_Data(recIndex).CostedByWeight
where
UPC = Item_Data(recIndex).UPC;
log_message(Item_Data(recIndex).Region, '', 'Updated item ' || Item_Data(recIndex).UPC || '.');
end loop;
EXCEPTION
WHEN OTHERS THEN
errcode := SQLCODE();
errmsg := SQLERRM();
log_message('CE', '', 'Error in Update_Item_Region_table(): Code [' || errcode || '], Msg [' || errmsg || '] ...');
END;
在我的 BizTalk 项目中,我为两个存储过程生成架构和绑定信息。对于 Oracle 过程,我为 GenelatedUserTypesAssemblyFilePath 参数指定了一个路径,以生成包含数据类型定义的 DLL。在服务器上的发送端口中,我将该类型 DLL 的路径放入 UserAssembliesLoadPath 参数中。
我创建了一个映射,将 GetItemChanges() 架构转换为 Update_Item_Region_Table() 架构。
当我运行它时,数据被提取并转换得很好,但在尝试将数据传递到 Oracle 过程时导致异常:
*适配器无法传输消息以发送端口“WcfSendPort_OracleDBBinding_HOST_DATA_Procedure_Custom”,URL 为“oracledb://dvotst/”。它将在为此发送端口指定的重试间隔后重新传输。详细信息:“System.InvalidOperationException:'HOST_DATA.TBL_OF_REC'的自定义类型映射未指定或无效。*
因此,它显然没有将有关自定义数据类型 TBL_OF_REC 的信息获取到类型 DLL 中。
有关如何执行此操作的任何提示工作?
I'm trying to set up a simple example project in BizTalk that gets changes made to a table in a SQL Server db and updates a copy of that table in an Oracle db.
On the SQL Server side, I have a stored proc named GetItemChanges() that returns a variable number of records.
On the Oracle side, I have a stored proc named Update_Item_Region_Table() designed to take a table of records as a parameter so that it can process all the records returned from GetItemChanges() in one call. It is defined like this:
create or replace type itemrec is OBJECT (
UPC VARCHAR2(15),
REGION VARCHAR2(5),
LONG_DESCRIPTION VARCHAR2(50),
POS_DESCRIPTION VARCHAR2(30),
POS_DEPT VARCHAR2(5),
ITEM_SIZE VARCHAR2(10),
ITEM_UOM VARCHAR2(5),
BRAND VARCHAR2(10),
ITEM_STATUS VARCHAR2(5),
TIME_STAMP VARCHAR2(20),
COSTEDBYWEIGHT INTEGER
);
create or replace type tbl_of_rec is table of itemrec;
create or replace PROCEDURE Update_Item_Region_table ( Item_Data tbl_of_rec )
IS
errcode integer;
errmsg varchar2(4000);
BEGIN
for recIndex in 1 .. Item_Data.COUNT
loop
update FL_ITEM_REGION_TEST set
Region = Item_Data(recIndex).Region,
Long_description = Item_Data(recIndex).Long_description,
Pos_Description = Item_Data(recIndex).Pos_description,
Pos_Dept = Item_Data(recIndex).Pos_dept,
Item_Size = Item_Data(recIndex).Item_Size,
Item_Uom = Item_Data(recIndex).Item_Uom,
Brand = Item_Data(recIndex).Brand,
Item_Status = Item_Data(recIndex).Item_Status,
Timestamp = to_date(Item_Data(recIndex).Time_stamp, 'yyyy-mm-dd HH24:mi:ss'),
CostedByWeight = Item_Data(recIndex).CostedByWeight
where
UPC = Item_Data(recIndex).UPC;
log_message(Item_Data(recIndex).Region, '', 'Updated item ' || Item_Data(recIndex).UPC || '.');
end loop;
EXCEPTION
WHEN OTHERS THEN
errcode := SQLCODE();
errmsg := SQLERRM();
log_message('CE', '', 'Error in Update_Item_Region_table(): Code [' || errcode || '], Msg [' || errmsg || '] ...');
END;
In my BizTalk project I generate the schemas and binding information for both stored procedures. For the Oracle procedure, I specified a path for the GeneratedUserTypesAssemblyFilePath parameter to generate a DLL to contain the definition of the data types. In the Send Port on the server, I put the path to that Types DLL in the UserAssembliesLoadPath parameter.
I created a map to translate the GetItemChanges() schema to the Update_Item_Region_Table() schema.
When I run it the data is extracted and transformed fine but causes an exception trying to pass the data to the Oracle proc:
*The adapter failed to transmit message going to send port "WcfSendPort_OracleDBBinding_HOST_DATA_Procedure_Custom" with URL "oracledb://dvotst/". It will be retransmitted after the retry interval specified for this Send Port. Details:"System.InvalidOperationException: Custom type mapping for 'HOST_DATA.TBL_OF_REC' is not specified or is invalid.*
So it is apparently not getting the information about the custom data type TBL_OF_REC into the Types DLL.
Any tips on how to make this work?

如果其他人在执行此类任务时遇到问题,我的问题是在生成架构和绑定文件之前没有正确设置所有属性。
GenerateUserTypesAssemblyFilePath <- 我有这个...
GenerateUserTypesAssemblyKeyFilePath <- 我没有这一套...我将其设置为与其余部分相同的强命名密钥文件的项目。
由于我必须在发送端口中提供 DLL 的完整路径,所以我认为它不需要在 GAC 中 - 但它确实如此 - 所以你必须手动添加它,因为部署过程只放置正常的项目 DLL进入 GAC。
我刚刚从 Visual Studio 命令窗口运行此命令:
In case anyone else has trouble with this type of task, my problem was not having all the properties set correctly before generating the schema and binding files.
GeneratedUserTypesAssemblyFilePath <- I had this one …
GeneratedUserTypesAssemblyKeyFilePath <- I did NOT have this one set … I set it to the same strong named key file I used for the rest of the projects.
Since I had to provide the full path to the DLL in the Send Port, I didn’t think it needed to be in the GAC – but it does - so you have to add it manually since the Deploy process only puts the normal project DLLs into the GAC.
I just ran this command from the Visual Studio command window:
