Hi all, I try to open a oracle connection like this:

DatabaseDataSourceSettings dbSettings = new DatabaseDataSourceSettings(
"System.Data.OracleClient",
"Data Source= jdbc:tibcosoftwareincracle:@rw-pc:1521:XE;user=Spotfire;pwd=Spotfire", String.Empty);

dbSettings.SqlStatement = "select * from v$version";
DatabaseDataSource ds = new DatabaseDataSource(dbSettings);
this.app.Open(ds);

But I receive always an error:

{"Failed to execute data source query."}

Inner Exception: {"User input is need"}

Any advice is welcome. Thank in advance.
