sqljdbc driver UNION querys
Hi all,
i am having a problem with the sqljdbc driver related with Union querys.
My sql query is in the form QUERY1 Union QUERY2 Union Query3.
At the sqlServerManager i can get the data of the 3 querys, but at my application i only get data of the first query.
Can anyone tell me if this is related with my driver?
thanks in advance

Doubt it.
The driver simply passes the SQL to the database.
If you showed us your code we might be able to point out the problem.

ok, this is my code:
Java Code:Statement statment = con.createStatement(); ResultSet resVentasCadenas = statment .executeQuery(Querys.queryVentasTotal); .......... .......... while (resVentasCadenas.next()) { .................... }

Which says nothing about your query.
What is the SQL?

Sorry about the delay,
the sql query sintax is as folllows and it is working in the sqlservermanager:
Java Code:select sum(v.importeConIva * p.cambioreferencia) as importeTicket, t.cadena, v.seccion, 'TTTT', p.pais, p.nombre from XXXXXX v, XXXXXX t, XXXXXX paises p where v.tienda = t.tienda and t.pais = p.pais and v.fecha = CONVERT(DATETIME, '02/14/2011') and t.cerrada = 0 and t.cadena = 1 and v.seccion in (1,2) group by t.cadena, p.pais, p.nombre ,v.seccion  ventas mismas tiendas UNION ALL select sum(v.importeConIva * p.cambioreferencia) as importeTicket, t.cadena, v.seccion, 'MMTT', p.pais, p.nombre from XXXXXX v, XXXXXX t, XXXXXX paises p where v.tienda = t.tienda and t.pais = p.pais and t.cadena = 1 and v.seccion in (1,2) and v.fecha = CONVERT(DATETIME, '02/14/2011') and 0 < (select count (*) from XXXXX v2 where v2.tienda = v.tienda and v2.fecha = CONVERT(DATETIME, '02/15/2010') and t.cerrada = 0 ) group by t.cadena, p.pais, p.nombre, v.seccion UNION ALL select sum(v.importeConIva * p.cambioreferencia) as importeTicket, t.cadena, v.seccion, 'MMTT_A1' , p.pais, p.nombre from XXXXXX v, XXXXXX t, XXXXXX paises p where v.tienda = t.tienda and t.pais = p.pais and v.fecha = CONVERT(DATETIME, '02/15/2010') and t.cerrada = 0 and t.cadena = 1 and v.seccion in (1,2) group by t.cadena, p.pais, p.nombre, v.seccion order by t.cadena, p.pais

Then you should get all of the information (in a single resultset of course). If you can prove that you do not, then create a small, selfcontained, compilable, executable program and the explicit data to go with it, that demonstrates the problem and submit that as a bug to the vendor from which you got the JDBC driver.

Java Code: ventas mismas tiendas
Since I suspect you are concatenating that String together then the above comment is actually commenting out all the remaining bit of the SQL, since it's all on one line as far as the database is concerned.
ETA: And in case anyone is wondering, yes I have done this. In Hibernate, on a large stored query that I wanted to try and document. Funnily enough the query didn't work since 90% of it was actually commented out.

Ok, thank you Tolls, i have changed what you said about comments.
Now my sql code is as follows, but now i am only getting data of the 3 sql union query. I have no results about the 2 first querys.
¿what's happening now?
Java Code:select sum(v.importeConIva * p.cambioreferencia) as importeTicket, t.cadena, v.seccion, 'TTTT', p.pais, p.nombre " + " from XXXX v, TTTTT t, PPPPPP p " + " where v.tienda = t.tienda " + " and t.pais = p.pais " + " and v.fecha = CONVERT(DATETIME, ?) " + " and t.cerrada = 0 and t.cadena = ? and v.seccion in (1,2) and p.pais = ? " + " group by t.cadena, p.pais, p.nombre ,v.seccion " + " UNION ALL" + " select sum(v.importeConIva * p.cambioreferencia) as importeTicket, t.cadena, v.seccion, 'MMTT', p.pais, p.nombre " + " from VVVVVVV v, TTTTTTTT t, PPPPPPP p " + " where v.tienda = t.tienda " + " and t.pais = p.pais and t.cadena = ? and v.seccion in (1,2) and p.pais = ? " + " and v.fecha = CONVERT(DATETIME, ?) " + " and 0 < (select count (*) " + " from VVVV v2 " + " where v2.tienda = v.tienda " + " and v2.fecha = CONVERT(DATETIME, ?)" + " and t.cerrada = 0 )" + " group by t.cadena, p.pais, p.nombre, v.seccion" + " UNION ALL" + " select sum(v.importeConIva * p.cambioreferencia) as importeTicket, t.cadena, v.seccion, 'MMTT_A1' , p.pais, p.nombre " + " from VVVVVVV v, TTTTTTTT t, PPPPPPPP p " + " where v.tienda = t.tienda " + " and t.pais = p.pais " + " and v.fecha = CONVERT(DATETIME, ?) " + " and t.cerrada = 0 and t.cadena = ? and v.seccion in (1,2) and p.pais = ? " + " group by t.cadena, p.pais, p.nombre, v.seccion

You've lost me there.
There are 3 parts to your query, which are UNIONed together.
You say you are getting data from these, so what are you having a problem with?
