MediaSet fields in Queries..

When designing queries in Dynamics NAV you’ll get an error i CSide if you include a BLOB field, but no error if you include a MediaSet field. At runtime, you’ll get this strange error:

Unable to compare operands of type NSMediaSetWrapper with NavMediaDescriptionCollection.

Remove your MediaSet field from the Query Object and everything works again.

Att Microsoft: Perhaps expand the BLOB check in FINSQL.EXE to include MediaSet fields also 🙂
