In This Topic

Gets the number of rows changed, inserted, or deleted by execution of the SQL statement.

Syntax

Visual Basic
C#

'Declaration
 
Public Overrides ReadOnly Property RecordsAffected As Integer

public override int RecordsAffected {get;}

Property Value

The number of rows changed, inserted, or deleted. -1 for SELECT statements; 0 if no rows were affected, or the statement failed.

Remarks

IsClosed and RecordsAffected are the only properties that you can call after the SqlShimDataReader is closed.

Example

This sample shows how to find out how many rows have been affected during last query. You can do it even if the SqlShimDataReader has been closed.

csharp

public void ProcessReader (SugarDataReader sugarReader)
{
  if (!sugarReader.IsClosed)
  {
    while (sugarReader.Read())
    {
      for (int i=0;i<sugarReader.FieldCount;i++)
      {
        Console.Write("\t"+sugarReader[i]);
      }
      Console.WriteLine();
    }
  }
  else
  {
    Console.WriteLine("The DataReader is closed. Rows affected in last action: "+sugarReader.RecordsAffected);
  }
}

Visual Basic

Public Sub ProcessReader(ByVal sugarReader As SugarDataReader)
  If Not sugarReader.IsClosed Then
    Dim i As Integer
    While sugarReader.Read()
      For i = 0 To sugarReader.FieldCount - 1
        Console.Write(" " & sugarReader(i))
      Next i
      Console.WriteLine()
    End While
  Else
    Console.WriteLine("The DataReader is closed. Rows affected in last action: " & sugarReader.RecordsAffected)
  End If
End Sub
