ArcSDE query attribute

[Hallgren Johan E]

Hello

 

I have tried to query a sde-layer but it fails.

 

I'm using mapserver-4.8.1

And ArcSDE 9.0 clientlib (windows XP)

And ArcSDE 9.0 on a Oracle 10.1 (windows Server)

All code is written in c#/mapscript/SWIG.

 

Drawing the layer is no problem but when querying, it gives an error
message:

"Error allocating layer items array."

 

The error occur when I run the oLayerObj.open() -command

 

Se the code below, I have used the same approach as with shapefiles. 

 

 

 

 

mapObj mo = new mapObj(mapFile.Text);

layerObj oLayerObj = mo.getLayerByName("SJ_large_sde");

oLayerObj.queryByRect(mo, oLayerObj.getExtent());

 

oLayerObj.queryByAttributes(mo, "KKOD", "", mapscript.MS_MULTIPLE);

resultCacheObj oResultCacheObj = oLayerObj.getResults();

oLayerObj.open(); // <-- Gives the error.

 

textBox1.Text = oResultCacheObj.numresults.ToString();

 

if (oResultCacheObj.numresults > 0)

{

int iFeatureLimit = oResultCacheObj.numresults;

 

           int lFeat = 0;

           for (lFeat = 0; lFeat < oResultCacheObj.numresults; lFeat++)

           {

                      if (lFeat == (iFeatureLimit + 0))

                                 break;

                      shapeObj oShapeObj =
oLayerObj.getFeature(lFeat,-1);

 

           }

}

 

 

Best Regards

Johan
