A note on EPiServer Commerce entry data and serialization

To improve performance, catalog entry meta data is serialized and stored in a field for each catalog entry. This allows all meta data information to be fetched from a single field and de-serialized, which reduces the number of database calls and greatly increases performance compared to non-serialized data fields.

The SerializedData field should be updated after updating any catalog data through 3rd party sources. The SerializedData field is part of the CatalogEntryDTO (data transfer object), and will be cached based on catalog cache settings. Storing images and files in meta fields will increase the size of the serialized data, and increase catalog cache size.

Simple SQL script to show all Associations in EPiServer Commerce 1

There seem to be no good way to show all Entry Assocations (e.g. entries that have listings for accesories or related products set),  in Commerce, so I just created some simple SQL scripts

Show all

SELECT CatalogAssociation.CatalogEntryId, CatalogEntry.Code, CatalogEntry.Name, CatalogAssociation.AssociationName
FROM    CatalogAssociation INNER JOIN
                 CatalogEntry ON CatalogAssociation.CatalogEntryId = CatalogEntry.CatalogEntryId

If you need the associated entries as well, dig into this table:
[dbo].[CatalogEntryAssociation]

Where association contains ‘Expired’

SELECT CatalogAssociation.CatalogEntryId, CatalogEntry.Code, CatalogEntry.Name, CatalogAssociation.AssociationName
FROM    CatalogAssociation INNER JOIN
                 CatalogEntry ON CatalogAssociation.CatalogEntryId = CatalogEntry.CatalogEntryId
				 where CatalogAssociation.AssociationName like '%Expired%'

Most common associations counted
A variant for showing the most common associations (counted) are:

SELECT distinct CatalogAssociation.AssociationName, Count(*) as Count 
FROM    CatalogAssociation INNER JOIN
                 CatalogEntry ON CatalogAssociation.CatalogEntryId = CatalogEntry.CatalogEntryId
				 GROUP BY AssociationName
				 order by Count Desc
