I'm runing Windows XP SP2 and when try move in a ResultSet I Obtain a 
SQLException

//I open a connection, loading the driver (I don't put try{}catch(){}):
Class.forName("interbase.interclient.Driver");
Connection 
Conexion=DriverManager.getConnection("jdbc:interbase://127.0.0.1/C:/COSA.gdb","pepito","pepito");
//make a Statement
Statement stmArticulos= conecta.getConexion().createStatement();
//make a query (Ok the database desing sucks but isn't my desing)
//change the dialect
stmArticulos.executeQuery("SET SQL DIALECT 1;");
ResultSet rsArticulos=stmArticulos.executeQuery("select 
PK_ARTICULO,MODIFICACION,REFERENCIA,NOMBRE,TIPO_IVA,TIPO_RECARGO,PVP1,PVP1_IVA,PVP2,PVP2_IVA,PVP3,PVP3_IVA,PVP4,PVP4_IVA 
from articulos")
//and try to move arround the resulset
             do{
             System.out.println(this.getRsArticulos().getString(1));
             }while (this.getRsArticulos().next());
and obtain a dialect error

Ok I read some webs and the problem must be in the Dialect


If Dialect is set to 3,2 or 1 I obtain this exception:

interbase.interclient.SQLException: [interclient][interbase] Dynamic SQL 
Error
SQL error code = -104
Token unknown - line 1, char 4
SQL

If i not set dialect removing the line stmArticulos.executeQuery("SET 
SQL DIALECT 1;"); I obtain this exception:

interbase.interclient.SQLException: [interclient][interbase] Dynamic SQL 
Error
SQL error code = -206
Column unknown
TIPO_IVA
Client SQL dialect 1 does not support reference to 64-bit numeric datatype

�Someone can help me?
