Using the latest version of OraDirect 4.20 the following fails with:

ORA-01008: not all variables bound

            OracleConnection oc = new OracleConnection();
            oc.Direct = true;
            oc.Server = "server";
            oc.Sid="sid";
            oc.UserId="username";
            oc.Password="password";
            oc.Open();

            OracleCommand ocmd = oc.CreateCommand();
            ocmd.ParameterCheck = true;
            ocmd.CommandText = "select :p1,:p1,:p2 from dual";
            ocmd.Prepare();
            ocmd.Parameters["p1"].Value = "00000";
            ocmd.Parameters["p2"].Value = "00001";
            OracleDataReader or = ocmd.ExecuteReader();

This works fine when Direct=false.

Seems to be related to the fact that there is a repeated parameter in the query.

We are investigating this behaviour.
Look forward to hearing from me again.

Unfortunately, we cannot fix this. You should not repeat parameters.

thats a shame because it works correctly when direct mode = false and we already have a number of queries that do this.

It means we will not be able to continue our investigation into using direct mode. Maybe you could update the documentation to list this as a limitation of direct mode so that other people are aware of this issue before devoting alot of time to trying to use direct mode in these circumstances.

We are going to overcome this problem in future. But please be warned that this will take much time, so plan your development strategy accordingly.

Not at all.

I got ORA-01008 (using the latest version of OraDirect as of today) when repeating the same parameter using direct mode.

Works fine for native connection and for SQL Server

Someone earlier in the this thread mentiond that this was an issue to be fixed at some stage.

What is the status?
