Question

When I execute sql query SELECT * FROM TABLE (TEST.getDevices()) in SqlDeveloper I’ve got about 200 rows, but when I try to execute it in java:

//cut here
String query = "SELECT * FROM TABLE (TEST.getDevices())"; 
PreparedStatement stmt = null; 
ResultSet rset = null; 
try { 
    stmt = oracleConnection.prepareStatement(query); 
    rset = stmt.executeQuery(); 
    rset.next(); 
    System.out.println(rset.getInt(1));
//cut here

I get empty ResultSet and so on the exception is thrown.
I’ve tried query SELECT Count(*) a FROM TABLE (TEST.getDevices())
In SqlDeveloper result is 200, in java app is 0.

What could be reason that get empty ResultSet in ma app?
