Limits the query results by including only the results that exist in another object query.
Assembly: System.Data.Entity (in System.Data.Entity.dll)
The query parameter is nullptr or is an empty string.
The supplied query that defines results to include must be of the same type or of a type that is compatible with the ObjectQuery<T>.
Parameters that are defined in the supplied query are merged with parameters that are defined in the ObjectQuery<T> instance. Parameters must be unique in the combined ObjectParameterCollection. There cannot be two parameters in the combined collection with the same name. For more information, see Query Builder Methods (Entity Framework).
The resulting query inherits the connection from the ObjectQuery<T> instance on which the method was called.
