Passing more than 32 KB Data to a Stored Procedure using ODP.Net Provider throws this error to me

" ORA-01460: unimplemented or unreasonable conversion requested"

The same code is working fine with oledb provider type but using ODP.Net it is giving this error if the fILE Size is Greater than 32 KB.

Is there any limitation passing greater than 32 KB.

Please let me know if any body knows ASAP.

Please suggest me if any other specific NewsGroup is there for ODP.Net



FileInfo fi=new FileInfo(@"C:\MyData\Old_Gautam_data\BLR-WS-119\songs\telugu\movies\letsc..txt");

StreamReader sr=new StreamReader(fi.FullName);

string tempbuff=sr.ReadToEnd();

CMD.AddParameter("vOut",null,ParameterDirection.Output,DbType.String,(int)tempbuff.Length);

CMD.AddParameter("vin",tempbuff,ParameterDirection.Input);

This is my sample Procedure which returns clob as out parameter:-->

CREATE OR REPLACE Procedure proctest(nIn Number,vOut out CLOB,vin in CLOB)
is
StrSql Varchar2(3000);
Begin
vOut := vin;
END;


Thanks
Gautam

You have to specify the type of the parameter for the CLOB input
parameter. You don't do that and ODP.NET then guesses what the type is
based on the value and likely will go for a varchar.

Hai Frans,

Thanks for responding to my post.

As u said I tried mentioning the datatype as CLOB for my in and out
parameters but eventhough I am facing the same problem.

Is there any other case which it will yield this type of error.Please
Suggest me if I am wrong

Thanks

Gautam

I could only think of the absense of the datatype for the parameter.
That's how I do it with ODP.NET, (specifying OracleDbType.Clob) and
that works well...

Could u just send me sample code of how ur doing with ODP.Net

That's inside my O/R mapper core, so it's not that easy to give you an
ODP.NET only example. I looked into my code to see if I did anything
special, but all I did was setting the parameter as follows:

/// < ... >
public override IDataParameter CreateParameter(IEntityFieldCore field,
IFieldPersistenceInfo persistenceInfo, ParameterDirection direction,
object valueToSet)
{
object value=base.GetRealValue(valueToSet,
persistenceInfo.TypeConverterToUse, persistenceInfo.ActualDotNetType);
if(value==null)
{
value=System.DBNull.Value;
}
if(value is System.Enum)
{
value=Convert.ToInt32(valueToSet);
}

OracleParameter toReturn = new OracleParameter();
toReturn.ParameterName = CreateParameterName(field.Alias);
toReturn.Direction=direction;
toReturn.IsNullable=persistenceInfo.SourceColumnIsNullable;
toReturn.Precision=persistenceInfo.SourceColumnPrecision;
toReturn.Scale=persistenceInfo.SourceColumnScale;
toReturn.Value=value;
if ((persistenceInfo.SourceColumnDbType == (int)OracleDbType.Clob) ||
(persistenceInfo.SourceColumnDbType == (int)OracleDbType.Blob) ||
(persistenceInfo.SourceColumnDbType == (int)OracleDbType.BFile) ||
(persistenceInfo.SourceColumnDbType == (int)OracleDbType.NClob))
{
toReturn.OracleDbType =
(OracleDbType)persistenceInfo.SourceColumnDbType;
}
else
{
toReturn.DbType =
SelectDbType((OracleDbType)persistenceInfo.SourceColumnDbType,
persistenceInfo.SourceColumnPrecision,
persistenceInfo.SourceColumnScale);
}

return toReturn;
}

THe call to SelectDbType is necessary to convert OracleDbType to
DbType values, but that's about it. As you can see, I don't do anything
special, though I do set the type after the value is set.
