FetchAll Property (MySqlCommand)
Gets or sets a value indicating whether the
MySqlDataReader object will request data from the server on execution
ExecuteReader method.
public bool FetchAll {get; set;}
'Declaration
Public Property FetchAll As Boolean
Property Value
true, if the
MySqlDataReader object will request data from the server on execution
ExecuteReader; otherwise
false. The default value is
false.
The following example fills a
MySqlDataReader and renders data to console. This sample demonstrates ability to navigate through the
MySqlDataReader (this can be done several times) when
FetchAll property is set to
true.
public void FetchThemAll(MySqlConnection myConnection)
{
MySqlCommand cmd = new MySqlCommand("SELECT EmpNo, EName FROM Emp");
cmd.FetchAll = true;
cmd.Connection = myConnection;
myConnection.Open();
MySqlDataReader reader = cmd.ExecuteReader();
foreach (IDataRecord rec in reader)
{
Console.Write(rec["EmpNo"]);
Console.WriteLine("\t"+rec["EName"]);
}
}
Public Sub FetchThemAll(ByVal myConnection As MySqlConnection)
Dim cmd As MySqlCommand = New MySqlCommand("SELECT EmpNo, EName FROM Emp")
cmd.FetchAll = True
cmd.Connection = myConnection
myConnection.Open()
Dim reader As MySqlDataReader = cmd.ExecuteReader()
For Each rec As IDataRecord In reader
Console.Write(rec("EmpNo"))
Console.WriteLine(String.Concat(" ", rec("EName")))
Next
End Sub
