Are there known problems using a string field as the key field in an SDF
file?
I'm trying to zoom to a filtered object, and it seems to work on an SDF
with a default integer FeatId key field, but fails when I try it on an
SDF with a string key field. The FeatureReader is always empty when I
try to get
Scenario #1 Works with an SDF with FeatId integer key
queryOptions.SetFilter("FeatId = 410");
MgResourceIdentifier featureResId = new
MgResourceIdentifier(layer.GetFeatureSourceId());
MgFeatureReader featureReader =
featureService.SelectFeatures(featureResId, layer.GetFeatureClassName(),
queryOptions);
Scenario #2 Fails with an SDF with a string key
queryOptions.SetFilter("ParcelID = '0102000'");
MgResourceIdentifier featureResId = new
MgResourceIdentifier(layer.GetFeatureSourceId());
MgFeatureReader featureReader =
featureService.SelectFeatures(featureResId, layer.GetFeatureClassName(),
queryOptions);
Any ideas greatly appreciated
