Question

Disclaimer: I don’t actually know anything about nether Oracle nor Java. The issue is in a project that some other developer completed at some point in time and then left the company. Now I have to setup webserver, database and get it all up and running.

the code is approx this:

OracleDataSource ods = new OracleDataSource();
ods.setURL("jdbc:oracle:thin:<user>/<password>@localhost:1521:xe");
OracleConnection ocon = (OracleConnection)ods.getConnection();
OracleStatement stmt = (OracleStatement)ocon.createStatement();
OracleResultSet rs = (OracleResultSet)stmt.executeQuery("SELECT POLLID, QUESTION, ISMULTISELECT FROM POLL WHERE POLLID = " + pollID);

if (!rs.next()) {
    System.out.println("No rows found.");
    return false;
}
this._PollID = rs.getInt("POLLID");
this._Question = rs.getString("QUESTION");
this._IsMultiSelect = rs.getBoolean("ISMULTISELECT");

The POLLID and ISMULTISELECT columns return correct values as expected. The QUESTION seem to always return empty string. The value in the DB is obviously not empty.

The rs.getAsciiStream("QUESTION").available() also returns zero.

Am I missing something completely obvious here?

EDIT:

• sqlplus returns varchar2 value just fine

• connecting via odbc (as opposed to thin) also makes things work

Answer 1

Thanks to everyone who replied. At this point it seems issue is between thin driver and XE version of Oracle. Unfortunately we don’t have full version kickin’ around (we are primarily ASP.NET/MS SQL developers), so we’ll have to stick with ODBC driver for now and hope issue will magically resolve itself when we push it to live environment (hosted by third party). Very crappy assumption to make, but at this point I see no other options….
