data type nvarchar and varchar are incopatible in the boolean and operator

I'm trying to convert a query from access to sql server


UPDATE [Shipments]
SET [Shipments].[TCM Route Id] = LTrim([sfpostal/zip code]) & 'to' & LTrim([st postal/zip code])
FROM [Shipments]
WHERE ((([Shipments].[Route Id]) Is Null Or ([Shipments].[Route Id]) Like Null));

this code works fine in access but will not run in sql server. I'm at a loss.

To concatenate two strings, just use the add operator (+). So it should be

LTrim([sfpostal/zip code]) + 'to' + LTrim([st postal/zip code])

Happy Coding!!!
