Hi,I have a SOE that is enabled on a MapService. This map service has one feature layer. what I am trying to do is to query features in this feature layer during SOE request process. I tried following query function:public ICursor PerformAttributeQuery(ITable table, string whereClause)
{
if (table == null)
{
return null;
}
IQueryFilter queryFilter = new QueryFilterClass();
queryFilter.WhereClause = whereClause; // create the where clause statement
try
{
// query the table passed into the function and use a cursor to hold the results
ICursor cursor = table.Search(queryFilter, false);
return cursor;
}
catch (Exception ex)
{
}
return null;
}
I used IMapServerDataAccess.GetDataSource to get this feature layer;Then this function is called to query a given feature layer, such as:ICursor cursor = PerformAttributeQuery((ITable)featureLayer, "OBJECTID = 120");
if (cursor != null)
{
//processing
//release cursor
Marshal.ReleaseComObject(cursor);
}
But during the query, I got the error saying:The workspace is not connectedI also tried directly using SpatialQuery via IFeatureClass.Search but didn't work either.I feel maybe featureclass query is only partly supported in SOE environment?does anybody have some inputs on this one? thank you!
