Example

In This Topic
    ExecuteReader(CommandBehavior) Method
    In This Topic
    Sends the CommandText to the Connection, and builds a MySqlDataReader using one of the System.Data.CommandBehavior values.
    Syntax
    'Declaration
     
    Public Overloads Shadows Function ExecuteReader( _
       ByVal behavior As CommandBehavior _
    ) As MySqlDataReader
    public new MySqlDataReader ExecuteReader( 
       CommandBehavior behavior
    )

    Parameters

    behavior
    One of the System.Data.CommandBehavior values.

    Return Value

    A MySqlDataReader object.
    Remarks

    When FetchAll property is false the following restriction takes place. While the MySqlDataReader is in use, the associated MySqlConnection is busy serving the MySqlDataReader. While in this state, no operations can be performed on the MySqlConnection except closing. This is the case until the Close() method of the MySqlDataReader is called.

    Example
    The following example creates a MySqlCommand, then executes it by passing a string that is SQL SELECT statement, and a string to use to connect to the data source. The System.Data.CommandBehavior is then set to CloseConnection.
    public void CreateMySqlDataReader(string mySelectQuery,string myConnectionString)
    {
      MySqlConnection myConnection = new MySqlConnection(myConnectionString);
      MySqlCommand myCommand = new MySqlCommand(mySelectQuery, myConnection);
      myCommand.Connection.Open();
      MySqlDataReader myReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection);
      while(myReader.Read())
      {
        Console.WriteLine(myReader.GetString(0));
      }
      myReader.Close();
    }
    Public Sub CreateMySqlDataReader(mySelectQuery As String, _
    myConnectionString As String)
      Dim myConnection As New MySqlConnection(myConnectionString)
      Dim myCommand As New MySqlCommand(mySelectQuery, myConnection)
      myCommand.Connection.Open()
      Dim myReader As MySqlDataReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection)
      While myReader.Read()
        Console.WriteLine(myReader.GetString(0))
      End While
      myReader.Close()
    End Sub
