Creates a new ObjectQuery<T> instance using the specified Entity SQL command as the initial query and the specified merge option.
Assembly: System.Data.Entity (in System.Data.Entity.dll)
public:
ObjectQuery(
String^ commandText,
ObjectContext^ context,
MergeOption mergeOption
)
Parameters
- commandText
-
Type:
System::String^
The Entity SQL query.
- context
-
Type:
System.Data.Objects::ObjectContext^
The ObjectContext on which to execute the query.
- mergeOption
-

Specifies how the entities that are retrieved through this query should be merged with the entities that have been returned from previous queries against the same ObjectContext.
When your application generates Entity SQL queries at runtime, you should be aware of any command length limitations of the data source. Entity SQL does not enforce limitations on the length of the command text in queries.
This example is based on the AdventureWorks Sales Model. The ObjectQuery<T> is initialized with the specified query, ObjectContext, and MergeOption.
