Example: Inserting and replacing catalog filters

We can insert or replace the catalog filters using the Data Load utility. These examples use a CSV file to demonstrate how to insert or replace the catalog filter data.

This example uses a CSV file to demonstrate how to insert, replace, or delete your data. We can also create and use an XML formatted file to insert, replace, or delete your data. If you choose to create and use an XML formatted file, ensure that your XML elements use the same names as are used for CSV column names.

Note: After you insert or update catalog filters with the Data Load utility, you need to update the
EXPRESSION database table. See dataload.

Prerequisites

• Ensure that the store exists.

• Ensure that the catalog data exists.

CSV file with sample data

CatalogFilter.csv The file contains sample catalog filter data. Each column is delimited by a comma. This example loads catalog filter data into the CATFILTER and CATFLTDSC tables.

Sample catalog filter data

CatalogFilterName	StoreIdentifier	CatalogIdentifier	Usage	EnglishDescription
CatalogFilterA	Aurora	Aurora	Buyer	ShortDesc for filter A
CatalogFilterB	Aurora	Aurora	Price	ShortDesc for filter B

CSV column and XML element definitions

CatalogFilterName

Required, String: The name of the catalog filter. Ensure that the combination of CatalogIdentifier, StoreIdentifier, and CatalogFilterName are unique.

StoreIdentifier

Required, String: The identifier of the store that the catalog filter belongs to.

CatalogIdentifier

Required, String: The identifier of the catalog that the catalog filter belongs to.

Usage

Optional, String: The usage of the catalog filter. The values are:

Hosting

For extended sites use.

Buyer

For contract use.

Price

For price use.

Promotion

For promotion use.

Marketing

For marketing use.

EnglishDescription

Optional, String: The description of the catalog filter in English. The description can also be added in other languages:

• GermanDescription

• ItalianDescription

• JapaneseDescription

• KoreanDescription

• PolishDescription

• PortugueseDescription

• RomanianDescription

• RussianDescription

• SChineseDescription

• SpanishDescription

• TChineseDescription

Other optional fields that are not included in the example:

CatalogFilterId

Optional, String: The reference number of the catalog filter. If the reference number is provided in the CSV, then it is used. If this field is provided, then the CatalogFilterName, CatalogFilterName, CatalogIdentifier is not needed.

Delete

Optional, String: Indicates whether to delete this record. This field takes effect when dataLoadMode is "replace". If the value of this field equals to deleteValue, the corresponding record is deleted. The default deleteValue is 1, deleteValue might be configured under DataMapping element in BusinessObjectConfigFile.

Field1

Optional, Long: Extension field for Long value.

Field2

Optional, Integer: Extension field for integer value.

Field3

Optional, String: Extension field for String value, the maximum length is 254.

Business context data

The following code snippet from the wc-dataload-env.xml configuration file provides the required business context data:

<_config:BusinessContext storeIdentifier="AuroraESite" catalogIdentifier="Extended Sites Catalog Asset Store">
</_config:BusinessContext>

storeIdentifier

String: The store identifier. This parameter is used when the storeIdentifier is not provided in the CSV file. If the storeIdentifier is provided in the CSV file, it is used. The storeIdentifier is used to retrieve the storeID and the ownerID.

catalogIdentifier

String: The catalog identifier. This parameter is used when the catalog identifier is not provided in the CSV file. If the catalogIdentifier is provided in the CSV file, it is used.

Mapping data

The following snippet from the sample configuration file demonstrates how to map each column of data in the source CSV file to a value.

<_config:DataReader 
     className="com.ibm.commerce.foundation.dataload.datareader.CSVReader" 
     firstLineIsHeader="true" 
     useHeaderAsColumnName="true" /> 

The following snippet from the sample configuration file demonstrates how to build a component business object that is based on the specified configuration properties, and the input data.

<_config:BusinessObjectBuilder className="com.ibm.commerce.foundation.dataload.businessobjectbuilder.BaseBusinessObjectBuilder" 
    	packageName="com.ibm.commerce.catalog.facade.datatypes.CatalogPackage" dataObjectType="CatalogFilterType" >

The following snippet from the sample configuration file demonstrates how to map each column of the data in the CSV file to a business object logical schema path. The attribute 'value' represents the name of a column of the CSV file, which is defined in the configuration snippet in the mapping column data sample. Each column in the CSV file must have a mapping to the logical schema path. If the optional fields specified in the mapping column data configuration are present in the CSV file, the mapping for them must be added. The mapping logical schema path is specified in the following table.

Business object mediator

The mediator class name is CatalogFilterMediator. The corresponding logical schema is CatalogFilter.xsd.

Note: When we use a mediator that is provided with WebSphere Commerce with the Data Load utility, the utility assumes that we are loading data for all columns for a business object. To update the data in only specific columns, configure a column exclusion list for the load process. A column exclusion list causes the Data Load utility to ignore specific columns during the load operation. If you do not use a column exclusion list, the utility updates all columns in the row of a database table row when the utility updates the row. If no value is set in the input file, the utility can replace the existing column value with a default value or set the value to be null. See Configure a column exclusion list.
