Problem with HasRows on FbDataReader
------------------------------------
Key: DNET-305
URL: http://tracker.firebirdsql.org/browse/DNET-305
Project: .NET Data provider
Issue Type: Bug
Components: ADO.NET Provider
Affects Versions: 2.5.1
Environment: XP Pro, FB ODS structure 11.1, Dialect 3, Firebird
ADO.NET Driver 2.5.1.0
Reporter: Steven Harris
Assignee: Jiri Cincura
Should the HasRows property return true if a datareader has no rows?
I can execute a query such as "select cus_id, cus_code, cus_name from customer
where cus_id = -1" and although there is no row with a cus_id of -1, the
HasRows property returns true.
Of course, when I do the dr.Read() and then dr.GetString(1) an exception occurs:
"There are no data to read"
I thought the HasRows property should indicate if there are rows to be read.
Otherwise the only way I can use it is to set up a try / catch structure which
seems incorrect.
