I was wondering if you've come across the situation I'm seeing. I have a query where I fetch a list of objects from the database and in the same query, I get an associated object e.g. I have a supplier which has a property called supplier type: Dim supplier = From suppliers In context.tbsuppliers Select New Web.Objects.Supplier() With { .SupplierID = suppliers.SupplierID, .SupplierType = (From supplierTypes In context.tbsuppliertypes Where suppliers.SupplierTypeID = supplierTypes.SupplierTypeID Select New Web.Objects.SupplierType With { .SupplierTypeID = supplierTypes.SupplierTypeID } } This works well is MsSql, but in MySql, I get an error saying the specified method is not supported. If I replace the supplierTypes.SupplierTypeID with a number, then the query works. Have you come across this? Thanks, Dave Hi Florent,

This works well is MsSql, but in MySql, I get an error saying the specified method is not supported. If I replace the supplierTypes.SupplierTypeID with a number, then the query works. Have you come across this?
