Hi Nicol and Bart,
It's a strange problem for Linux box, what GCC are you using, 4.0?
I will check this problem, I saw a problem here with query's when I
defined a filter parameter for my layer. But it isn't the problem in
your case, or did you denine any filter for the layer in your mapscript?.
Here I used in a project this code to retrieve the data from Oracle
layer:
$camada->open();
for($i = 0; $i < $total_results; $i++)
{
$sindex = $camada->getResult($i);
$result = $camada->getShape(-1,$sindex->shapeindex);
if ($result->type == 0)
{
$x = $result->bounds->minx;
$y = $result->bounds->miny;
$ponto_temp = ms_newpointObj();
$ponto_temp->setXY($x, $y);
if ($rectangle->contains($ponto_temp))
{
$arraytmp =
array($result->values[$nm_campo_sel],$result->values[$desc]);
array_push($resultado_selecao[$nm_campo_array],
$arraytmp);
}
$ponto_temp->free();
}
else
{
if(($rectangle->intersects($result) == MS_TRUE))
{
$arraytmp =
array($result->values[$nm_campo_sel],$result->values[$desc]);
array_push($resultado_selecao[$nm_campo_array],
$arraytmp);
}
}
$result->free();
}
$camada->close();
In this code I executed a "open" before retrieve the shapes ($camada
is a layerobj). Did you execute this function before the getshape? (I
used "-1" for tile index too).
The problem with Oracle Spatial and "--enable-point-z" flag was
solved, you can see this in #1244 Mapserver bugzilla.
Thanks.
