Represents a SQL query for entities that is created from a DbContext and is executed using the connection from that context. Instances of this class are obtained from the DbSet<TEntity> instance for the entity type. The query is not executed when this object is created; it is executed each time it is enumerated, for example by using foreach. SQL queries for non-entities are created using SqlQuery<TElement>(String, Object[]). See DbSqlQuery for a non-generic version of this class.

Constructors
| DbSqlQuery<TEntity>() |
Creates an instance of a DbSqlQuery<TEntity> when called from the constructor of a derived type that will be used as a test double for SqlQuery(String, Object[]). Methods and properties that will be used by the test double must be implemented by the test double except AsNoTracking and AsStreaming where the default implementation is a no-op. |
