FieldCount Property (DB2DataReader)
Gets the number of columns in the current row.
public override int FieldCount {get;}
'Declaration
Public Overrides ReadOnly Property FieldCount As Integer
Property Value
When not positioned in a valid record set, 0; otherwise the number of columns in the current record. The default value is -1.
This sample demonstrates how to iterate through fields in a row using
FieldCount property.
public void FetchResults(DB2Connection db2Connection)
{
DB2Command cmd = new DB2Command("SELECT * FROM Dept");
cmd.FetchSize = 100;
cmd.Connection = db2Connection;
db2Connection.Open();
try
{
DB2DataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
for (int i=0;i<reader.FieldCount;i++)
{
Console.Write("\t"+reader[i]);
}
Console.WriteLine();
}
}
finally
{
db2Connection.Close();
}
}
Public Sub FetchResults(ByVal db2Connection As DB2Connection)
Dim cmd As DB2Command = New DB2Command("SELECT * FROM Dept")
cmd.FetchSize = 100
cmd.Connection = db2Connection
db2Connection.Open()
Try
Dim reader As DB2DataReader = cmd.ExecuteReader()
While reader.Read()
Dim i
For i = 0 To reader.FieldCount - 1
Console.Write(String.Concat(" ", reader(i)))
Next i
Console.WriteLine()
End While
Finally
db2Connection.Close()
End Try
End Sub
