Remarks

The ZohoDeskCommand class provides the following methods for executing commands against Zoho Desk:

Item	Description
ExecuteReader	Executes commands that return rows.
ExecutePageReader	Returns a specific subset of rows when paging through the results of a query.
ExecuteNonQuery	Executes SQL commands such as INSERT, DELETE, UPDATE.
ExecuteScalar	Retrieves a single value (for example, an aggregate value) from a data source.

This class supports cross-form data binding with the InterForm Technology.

Example

The following example uses the ExecuteReader method of ZohoDeskCommand, along with ZohoDeskDataReader and ZohoDeskConnection, to select rows from a table.

csharp

public void ReadMyData(string myConnString)
{
  string mySelectQuery = "SELECT AccountID, \"Account Name\" FROM Accounts";
  ZohoDeskConnection ZohoDeskConnection = new ZohoDeskConnection(myConnString);
  ZohoDeskCommand ZohoDeskCommand = new ZohoDeskCommand(mySelectQuery,ZohoDeskConnection);
  ZohoDeskConnection.Open();
  ZohoDeskDataReader ZohoDeskReader = ZohoDeskCommand.ExecuteReader();
  try
  {
    while (ZohoDeskReader.Read())
    {
      Console.WriteLine(ZohoDeskReader.GetString(0) + ", " + ZohoDeskReader.GetString(1));
    }
  }
  finally
  {
  // always call Close when done reading.
  ZohoDeskReader.Close();
  // always call Close when done reading.
  ZohoDeskConnection.Close();
  }
}

Visual Basic

Public Sub ReadMyData(myConnString As String)
  Dim mySelectQuery As String = "SELECT AccountID, \"Account Name\" FROM Accounts"
  Dim ZohoDeskConnection As New ZohoDeskConnection(myConnString)
  Dim ZohoDeskCommand As New ZohoDeskCommand(mySelectQuery, ZohoDeskConnection)
  ZohoDeskConnection.Open()
  Dim ZohoDeskReader As ZohoDeskDataReader = ZohoDeskCommand.ExecuteReader()
  Try
    While ZohoDeskReader.Read()
      Console.WriteLine(ZohoDeskReader.GetString(0) + ", " _
        + ZohoDeskReader.GetString(1))
    End While
  Finally
      ' always call Close when done reading.
      ZohoDeskReader.Close()
      ' always call Close when done with connection.
      ZohoDeskConnection.Close()
  End Try
