[Visual Basic] Overloads Public Function ExecuteReader() As OleDbDataReader
[C#] public OleDbDataReader ExecuteReader();
[C++] public: OleDbDataReader* ExecuteReader();
[JScript] public function ExecuteReader() : OleDbDataReader;

Sends the CommandText to the Connection, and builds an OleDbDataReader using one of the CommandBehavior values.

[Visual Basic] Overloads Public Function ExecuteReader(CommandBehavior) As OleDbDataReader
[C#] public OleDbDataReader ExecuteReader(CommandBehavior);
[C++] public: OleDbDataReader* ExecuteReader(CommandBehavior);
[JScript] public function ExecuteReader(CommandBehavior) : OleDbDataReader;


[Visual Basic, C#, C++] The following example creates an OleDbCommand, then executes it by passing a string that is a Transact-SQL SELECT statement, and a string to use to connect to the data source. CommandBehavior is set to CloseConnection.

[Visual Basic, C#, C++] Note   This example shows how to use one of the overloaded versions of ExecuteReader. For other examples that might be available, see the individual overload topics.
[Visual Basic] 
Public Sub CreateMyOleDbDataReader(mySelectQuery As String, _
myConnectionString As String)
    Dim myConnection As New OleDbConnection(myConnectionString)
    Dim myCommand As New OleDbCommand(mySelectQuery, myConnection)
    Dim myReader As OleDbDataReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection)
    While myReader.Read()
    End While
    'Implicitly closes the connection because CommandBehavior.CloseConnection was specified.
 End Sub

public void CreateMyOleDbDataReader(string mySelectQuery,string myConnectionString) 
   OleDbConnection myConnection = new OleDbConnection(myConnectionString);
   OleDbCommand myCommand = new OleDbCommand(mySelectQuery, myConnection);
   OleDbDataReader myReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection);
   //Implicitly closes the connection because CommandBehavior.CloseConnection was specified.

    void CreateMyOleDbDataReader(String* mySelectQuery, String* myConnectionString)
        OleDbConnection* myConnection = new OleDbConnection(myConnectionString);
        OleDbCommand* myCommand = new OleDbCommand(mySelectQuery, myConnection);
        OleDbDataReader* myReader = myCommand->ExecuteReader(CommandBehavior::CloseConnection);
        //Implicitly closes the connection because CommandBehavior::CloseConnection was specified.
