Devart.Data Namespace / SqlShimDataReader Class / Read Method
Example

Read Method (SqlShimDataReader)
Advances the SqlShimDataReader to the next record.
Syntax
'Declaration
 
Public Overrides Function Read() As Boolean
 

Return Value

true if there are more rows; otherwise, false.
Remarks
The default position of the SqlShimDataReader is prior to the first record. Therefore, you must call Read to begin accessing any data.

While the SqlShimDataReader is in use, the associated Devart.Data.QuickBooks.QuickBooksConnection is busy serving it until you call Close.

Example
The following example creates a Devart.Data.QuickBooks.QuickBooksConnection, a Devart.Data.QuickBooks.QuickBooksCommand, and a SqlShimDataReader. The example reads through the data, writing it out to the console. Finally, the example closes the SqlShimDataReader, then the Devart.Data.QuickBooks.QuickBooksConnection.
public void ReadMyData(string myConnString)
{
  string mySelectQuery = "SELECT Id, DisplayName FROM Customer";
  QuickBooksConnection quickBooksConnection = new QuickBooksConnection(myConnString);
  QuickBooksCommand quickBooksCommand = new QuickBooksCommand(mySelectQuery,quickBooksConnection);
  quickBooksConnection.Open();
  QuickBooksDataReader quickBooksReader;
  quickBooksReader = quickBooksCommand.ExecuteReader();
  // Always call Read before accessing data.
  while (quickBooksReader.Read()) {
    Console.WriteLine(quickBooksReader.GetString(0) + ", " + quickBooksReader.GetString(1));
  }
  // always call Close when done reading.
  quickBooksReader.Close();
  // Close the connection when done with it.
  quickBooksConnection.Close();
}
Public Sub ReadMyData(myConnString As String)
  Dim mySelectQuery As String = "SELECT Id, DisplayName FROM Customer"
  Dim quickBooksConnection As New QuickBooksConnection(myConnString)
  Dim quickBooksCommand As New QuickBooksCommand(mySelectQuery, quickBooksConnection)
  quickBooksConnection.Open()
  Dim quickBooksReader As QuickBooksDataReader
  quickBooksReader = quickBooksCommand.ExecuteReader()
  ' Always call Read before accessing data.
  While quickBooksReader.Read()
    Console.WriteLine(quickBooksReader.GetString(0) + ", " _
      + quickBooksReader.GetString(1))
  End While
  ' always call Close when done reading.
  quickBooksReader.Close()
  ' Close the connection when done with it.
  quickBooksConnection.Close()
End Sub
