Here is my line

SET @filter = @filter + ‘  J.EngineerID = ”’ + @engineerID  + ””
but i get this error
The data types nvarchar and uniqueidentifier are incompatible in the add operator.

Solution: The data types nvarchar and uniqueidentifier are incompatible in the add operator.

CAST(unidColumn as nVarchar )
