ODP.NET 12C oracle.manageddataaccess.dll 4.121.2.0 / error unsupported column type

Question

0.00/5 (No votes)

See more:

I have replaced the "Oracle.DataAccess.dll" in my visual studio with "Oracle.ManagedDataAccess.dll" 4.121.2.0 and the build was successful.

but when I try to run the code it errors out saying
"unsupported column type".at

C#

cmdObj.ExecuteNonQuery();

But I have read that this latest version supports "xmltype" column but why is it failing? do I have to make any changes?

[EDIT - the code throwing the exception (from OP comment)]

C#

try
 {
 Oracle.ManagedDataAccess.Client.OracleConnection connObj = new Oracle.ManagedDataAccess.Client.OracleConnection();
 //OracleConnection objConn = new OracleConnection();
 connObj.ConnectionString = "Data Source=" + Constants.DataSource + "; User ID=" + Constants.UserId + "; Password=" + Constants.Password;
 Oracle.ManagedDataAccess.Client.OracleCommand cmdObj = new Oracle.ManagedDataAccess.Client.OracleCommand("GetXSLT", connObj);
 cmdObj.CommandType = CommandType.StoredProcedure;

 cmdObj.Parameters.Add("XSLTName", Oracle.ManagedDataAccess.Client.OracleDbType.Varchar2).Value = xsltName;
 cmdObj.Parameters.Add("ReqXSLT", Oracle.ManagedDataAccess.Client.OracleDbType.XmlType).Direction = ParameterDirection.Output;
 connObj.Open();
 cmdObj.ExecuteNonQuery();

What I have tried:

I have replaced the  "Oracle.DataAccess.dll"  in my visual studio with "Oracle.ManagedDataAccess.dll" 4.121.2.0 and the build was successful.

It might help to share the code that is failing

Oracle.ManagedDataAccess.Types.OracleXmlType xmlType;

try
{
Oracle.ManagedDataAccess.Client.OracleConnection connObj = new Oracle.ManagedDataAccess.Client.OracleConnection();
//OracleConnection objConn = new OracleConnection();
connObj.ConnectionString = "Data Source=" + Constants.DataSource + "; User ID=" + Constants.UserId + "; Password=" + Constants.Password;
Oracle.ManagedDataAccess.Client.OracleCommand cmdObj = new Oracle.ManagedDataAccess.Client.OracleCommand("GetXSLT", connObj);
cmdObj.CommandType = CommandType.StoredProcedure;

cmdObj.Parameters.Add("XSLTName", Oracle.ManagedDataAccess.Client.OracleDbType.Varchar2).Value = xsltName;
cmdObj.Parameters.Add("ReqXSLT", Oracle.ManagedDataAccess.Client.OracleDbType.XmlType).Direction = ParameterDirection.Output;
connObj.Open();

i read that article it says, xmltype is being supported since odac release 3,I am now using odac release4, that is why am wondering if some thing is wrong in code or its something related to dll.

I am running into the same issue. However, in our case it does not happen on all servers that we have. The same stored procedure call will give this error on one server and work just fine on another with the only difference being the server. Has anyone else experienced this and been able to pinpoint what the difference is?

I have an oracle support ticket open. I'll update this thread if I get anything useful out of it.
