Database checkpoint issue

function checkout()

{

var Conn

Conn= ADO.CreateConnection()

Conn.ConnectionString="Provider=MSDAXXX.1;Persist Security Info=False;User ID=XXXXXX;Password=XXXXXX;Data Source=source_source";

Conn.Open();

Cmd = ADO.CreateCommand();

Cmd.ActiveConnection = Conn;

Cmd.CommandType = adCmdText;

Cmd.CommandText = "select * from table_info where contact_email ='specific.email@specific.com'";

RecSet = Cmd.Execute();

RecSet.MoveFirst();

while (! RecSet.EOF )

{

Log.Message(RecSet.Fields("Value1").Value, RecSet.Fields("Value2").Value);

RecSet.MoveNext();

}

Conn.Close();

}



Then I considered doing database checkpoint and I failed and don't have a clue why :). I used connection string as copy-paste from working code and chose checkbox Custom Query option after which I copy paste the query but I tend to get error "Data provider or other service returned E-fail statement".



Any hints how to solve that?
