OracleCommand.ExecuteReader Method

Sends the CommandText to the Connection and builds an OracleDataReader.

Namespace:  System.Data.OracleClient
Assembly:  System.Data.OracleClient (in System.Data.OracleClient.dll)

'Declaration
Public Function ExecuteReader As OracleDataReader

When the CommandType property is set to StoredProcedure, the CommandText property should be set to the name of the stored procedure. The command then executes this stored procedure when you call ExecuteReader.

More than one OracleDataReader can be open at any given time.

The following example creates an OracleCommand, and then executes it by passing a string that is an SQL SELECT statement, and a string to use to connect to the data source.


Public Sub CreateMyOracleDataReader(ByVal queryString As String, _
ByVal connectionString As String)
    Using connection As New OracleConnection(connectionString)
        Dim command As New OracleCommand(queryString, connection)
        connection.Open()
        Dim reader As OracleDataReader = command.ExecuteReader()
        Try
            While reader.Read()
                Console.WriteLine(reader.GetValue(0))
            End While
        Finally
            reader.Close()
        End Try
    End Using
End Sub
