I am using vb.net sqlite.net and dblinq0.20.1 to search a sqlite table on a primary key field.
My code looks like this
Dim blb = (From d In db.Data Where d.UID = myuid Select d).Single
This returns the error “Coalesce used with type that cannot be null”
If I search on a nullable field it works fine.
Anyone come across this error before and throw any light on what the issue is?
This error message was a bit misleading. The field in question (the primary key for the table) was in fact nullable whereas it should not have been. I changed the field property to ‘not null’ and the linq query worked as expected.
