How to map list of attributes to column-based schema with condition in BizTalk? - schema

Question

I have two schema one is for input xml file and second is for database table.
Please look below for source data of above schema:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type='text/xsl'?>
<List>
<Classification domain="Type">deviceSku</Classification>
<Classification domain="Color">(PRODUCT)RED</Classification>
<Classification domain="ColorCode">#D82E2E</Classification>
<Classification domain="OS">Apple iOS</Classification>
<Classification domain="ChargeType">One Time Charge</Classification>
<Classification domain="Capacity">128GB</Classification>
</List>
Above file is input xml file which is in list form.
Please look below for table creation scripts which is output, and it is based on column format.
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[cata_class](
[ID] [int] IDENTITY(1000,1) NOT NULL,
[classification_type] [varchar](100) NULL,
[classification_color] [varchar](100) NULL,
[classification_colorCode] [varchar](50) NULL,
[classification_os] [varchar](100) NULL,
[classification_chargetype] [varchar](100) NULL,
[classification_capacity] [varchar](100) NULL,
PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF) ON [PRIMARY]
)
GO
As per above SS. I want to add classification value based on condition of domain in destination schema so which functiod is better option and how to use that function?

Answer 1

We need to use Equal and Value mapping (flattering) function as per below SS:
On equal functiod we need to pass domain to check condition as below:
and in value mapping (flattering) functiod we need to pass equal functiod value as first input and classification node as second input and map it to destination schema node.
