[Mono-list] StoredProcedure Output Parameters System.Data.Odbc

[Bartolomeo Nicolotti]

Hi,

I'm trying unixodbc with System.Data.ODBC to access DB2 for iseries

I can do select, see this file 
http://www.nabble.com/file/p21997635/helloODBC.cs helloODBC.cs , but I've
some problems with out parameters of stored procedueres.

With this file  http://www.nabble.com/file/p21997635/helloODBCCommand.cs
helloODBCCommand.cs  I get:

Hello, Dunkel
Eseguo:CALL QGPL.WBC022(9)
Eseguo:CALL GIANLUCA.PROVACS
System.Data.Odbc.OdbcException: ERROR [42000] [unixODBC][IBM][iSeries Access

END GET SET CALL DROP FREE HOLD LOCK OPEN WITH ALTER.


It seems that setting the CommandType to StoredProcedure has no effect, as
one can also see from the source of mono (I've installed mono from source)

/home/siap/dwn/src/mono/mono-2.2/mcs/class/System.Data/System.Data.Odbc/OdbcCommand

the ExecuteNonQuery member function call ExecSQL that


private int ExecuteNonQuery (bool freeHandle)
                {
...
                        ExecSQL(CommandText);

ExecSQL is:

                private void ExecSQL (string sql)
                {
                        OdbcReturn ret;
                        if (! prepared && Parameters.Count <= 0) {

                                ReAllocStatment ();
                               
                                ret = libodbc.SQLExecDirect (hstmt, sql,
libodbc.SQL_NTS);
                                if ((ret != OdbcReturn.Success) && (ret !=
OdbcReturn.SuccessWithInfo) &&
                                    (ret != OdbcReturn.NoData))
                                        throw connection.CreateOdbcException
(OdbcHandleType.Stmt, hstmt);
                                return;
                        }

                        if (!prepared)
                                Prepare();

                        BindParameters ();
                        ret = libodbc.SQLExecute (hstmt);
                        if (ret != OdbcReturn.Success && ret !=
OdbcReturn.SuccessWithInfo)
                                throw connection.CreateOdbcException
(OdbcHandleType.Stmt, hstmt);
                }

Should I use prepared to BindParameters?

How can I get the output parameter of a Stored Procedure?

Many thanks

Best regards
