RemoteTableQuery<T>

Overview

The RemoteTableQuery class is used in DA LINQ to represent queries to remote data sources. It contains a query expression tree and additionally implements the that is required for representing query results.

The generic type T defines the type of the data in the data source.

The RemoteTableQuery is a base class for the RemoteTable, which implements logic for the DA LINQ provider.

Implements

 

constructor

Default constructor that creates an instance of the RemoteTableQuery.

 

constructor

 

RemoteTableQuery<T>()

 

Sub New

constructor (IRemoteQueryProvider, Expression)

Creates a new instance of the RemoteTableQuery and associates it with a LINQ Expression and provider.

 

constructor(aProvider: IRemoteQueryProvider; aExpression: Expression)

 

RemoteTableQuery<T>(IRemoteQueryProvider aProvider, Expression aExpression)

 

Sub New (aProvider As IRemoteQueryProvider, aExpression As Expression)

Parameters:

  • aProvider: Implementor of IRemoteQueryProvider that is able to execute aExpression.
  • aExpression: LINQ Expression appropriate to current instance.

ElementType

Returns a generic type for the current class instance.
For example, if the RemoteTableQuery<T> is instantiated like the RemoteTableQuery<Worker>, this property will return the type of the Worker class.

 

property ElementType: Type read;

 

Type ElementType { get; }

 

Property ReadOnly ElementType As Type

Expression

Returns the LINQ expression tree of the current instance.

 

property Expression: Expression read write;

 

Expression Expression { get; set; }

 

Property Expression As Expression

Returns the result of a query execution as enumarable collection.
Implementation of the IRemoteTableQuery.

Returns an enumerator of generic type through the result of the query execution.
Implementation of the .

IEnumerator GetEnumerator2()

 

Function GetEnumerator2 As IEnumerator

Provider

 

property Provider: IQueryProvider read;

 

IQueryProvider Provider { get; }

 

Property ReadOnly Provider As IQueryProvider

ToString

Returns the SQL text of the assosiated LINQ Expression.

 

method ToString: String

 

String ToString()

 

Function ToString As String

 

ElementType

Property ReadOnly ElementType As Type

Expression

Returns the LINQ expression tree of the current instance.
