Error in migration from Episerver 8 to 9


Hi Episerver,

I am currently upgrading an application from Episerver 8.11 to 9.12 and Commerce 8.16 to 9.24.

During the EPiServer Commerce Migration of CatalogEntryEx_Product I encountered an SqlException: 'System.Data.SqlClient.SqlException (0x80131904): Cannot create a row of size 10351 which is greater than the allowable maximum row size of 8060.

After a few hours of debugging, I found that this happens in the stored procedure [mdpsp_avto_CatalogEntryEx_Product_ListSpecificRecord]. We solved this issue by adding option (ROBUST PLAN) to the stored procedure, afterwards the migration completed.

I know this error occurs because we have a large amount of product attributes(400+), but I still thought I would share this bug.

Great catch! Throw it into development support and I'm sure they will fix it

Although they scan forum off and on it's not bullet proof :)

yes, if you can spare the time, please send this to developer support as a bug report. A reason to channel it through developer support is that you can provide a description of this catalog design containing that many fields, without exposing it on the public forum. Examples of different catalog designs is valuable input to future system designs. And the workaround can be valuable for support to know about. 

I can't promise we'll accept the bug, most catalog designs come nowhere near this amount of fields for the same meta class, and using the ROBUST PLAN option could have performance implications for all those that don't need it. And once the migration is done, this sproc will be removed since it is not used in the remodeled catalog system. But as mentioned, we are interested in knowing more about different catalog designs.

Thank you!
