IngresDataReader Class
IngresDataReader provides a means of reading a forward-only stream of rows from a result-set created by a SELECT query or a row-producing database procedure.
When an IngresDataReader is open, the IngresConnection is busy and no other operations are allowed on the IngresConnection (other than IngresConnection.Close) until IngresDataReader.Close is issued. Created by the IngresCommand.ExecuteReader methods.
