Cassandra Oledb Provider Sample crashes

Postby eugeneng » Mon Apr 28, 2014 12:29 am

HI, recently I downloaded and installed the trial version of Cassandra Oledb Provider. when I try to run the C# sample, it crashes at :

file : 02_SimpleQuery.cs
line 24
public static int Sample02_SimpleQuery(OleDbConnection conn)
{
ConsoleWriteSampleHeader("[Sample 2.1] Getting records from database using OleDbDataReader.");
String lastStmt = "";

try
{
// Read records from pgnp_samples.contact table.
OleDbCommand cmd = conn.CreateCommand();
cmd.CommandText = lastStmt = "SELECT \"FirstName\",\"LastName\",active,\"HireDate\" FROM \"CasoTestEmployee\" LIMIT 5;";
OleDbDataReader reader = cmd.ExecuteReader(); <------Crashes here!!


with System Access Violation exception: {"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."}

and I received similar error when I tried to use SSIS to import 10 rows of record into Cassandra database.

is this the limitation of the trial version?

No, probably not. What is Cassandra version you use?

We have fixed the Cassandra provider and updated C# Samples (http://www.pgoledb.com/index.php?option ... &Itemid=68)
