Add Feature Class to Map in ArcGIS Pro

JaredPilbeam2

How do I add a feature class from an SDE to a Map in Pro? This is where most of our data is stored.

Here's what I've tried:

<SPAN class="keyword token">import</SPAN> arcpy
p <SPAN class="operator token">=</SPAN> arcpy<SPAN class="punctuation token">.</SPAN>mp<SPAN class="punctuation token">.</SPAN>ArcGISProject<SPAN class="punctuation token">(</SPAN><SPAN class="string token">"CURRENT"</SPAN><SPAN class="punctuation token">)</SPAN>
map <SPAN class="operator token">=</SPAN> p<SPAN class="punctuation token">.</SPAN>listMaps<SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">[</SPAN><SPAN class="number token">0</SPAN><SPAN class="punctuation token">]</SPAN>

<SPAN class="comment token">#this returned a ValueError</SPAN>
map<SPAN class="punctuation token">.</SPAN>addLayer<SPAN class="punctuation token">(</SPAN>r<SPAN class="string token">"Database Connections\path\to\gisedit.DBO.Address_Points"</SPAN><SPAN class="punctuation token">)</SPAN> 

<SPAN class="comment token">#this returned a RuntimeError</SPAN>
map<SPAN class="punctuation token">.</SPAN>addDataFromPath<SPAN class="punctuation token">(</SPAN>r<SPAN class="string token">"Database Connections\path\to\gisedit.DBO.Address_Points"</SPAN><SPAN class="punctuation token">)</SPAN>

‍‍‍‍‍‍‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

All the methods for using classes seem to be referencing layer files, and nowhere do I see a reference to feature classes.

EDIT:

The confusing thing is that when feature classes from the SDE are in the Map they're referred to as layers. The CURRENT project I'm testing on already has two feature classes from an SDE in it. You can list them with the following:

<SPAN class="keyword token">for</SPAN> lyrname <SPAN class="keyword token">in</SPAN> map<SPAN class="punctuation token">.</SPAN>listLayers<SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">:</SPAN>
    <SPAN class="keyword token">print</SPAN><SPAN class="punctuation token">(</SPAN>lyrname<SPAN class="punctuation token">.</SPAN>name<SPAN class="punctuation token">)</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

In your original post, it looked like you are using the 'Database Connections' ArcGIS application alias. Have you tried specifying the full Windows file system path to the SDE connection file and feature class?

I was working on the same problem with a SQL enterprise geodatabase. I had to use the fully qualified feature class name for it to be added to the map: DatabaseName.SchemaName.FeatureClassName.

Joshua,

I ran the same few lines of code that you have, but instead I'm directing the path to a Feature Class in an .SDE.

Here's the full error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "c:\program files\arcgis\pro\Resources\arcpy\arcpy\_mp.py", line 1248, in addDataFromPath
    return convertArcObjectToPythonObject(self._arc_object.addDataFromPath(*gp_fixargs((data_path,), True)))
RuntimeError‍‍‍‍‍‍‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Ok, Thanks. I'll have to get back to this on Thursday. Our building is being closed because of the cold weather.

Yes, FGDB feature class. Regarding your error, it is helpful to provide the full error with traceback.

JaredPilbeam2

I'm using Pro 2.0.

If you look at line 9 above that's what I did pretty much (also noted the errors above)

Is your feature class coming from a FGDB? Because I'm able to add a feature class from a FGDB. The thing is I'm trying to bring in a feature class from an SDE.

From the interactive Python window in ArcGIS Pro, the following code works for me, i.e., adds a feature class as a new layer in an open map window:

<SPAN class="keyword token">import</SPAN> arcpy

fc <SPAN class="operator token">=</SPAN> <SPAN class="comment token"># path to feature class</SPAN>

p <SPAN class="operator token">=</SPAN> arcpy<SPAN class="punctuation token">.</SPAN>mp<SPAN class="punctuation token">.</SPAN>ArcGISProject<SPAN class="punctuation token">(</SPAN><SPAN class="string token">"CURRENT"</SPAN><SPAN class="punctuation token">)</SPAN>
map <SPAN class="operator token">=</SPAN> p<SPAN class="punctuation token">.</SPAN>listMaps<SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">[</SPAN><SPAN class="number token">0</SPAN><SPAN class="punctuation token">]</SPAN>
map<SPAN class="punctuation token">.</SPAN>addDataFromPath<SPAN class="punctuation token">(</SPAN>fc<SPAN class="punctuation token">)</SPAN>
<SPAN class="operator token"><</SPAN>arcpy<SPAN class="punctuation token">.</SPAN>_mp<SPAN class="punctuation token">.</SPAN>Layer object at <SPAN class="number token">0x000002549A35FF28</SPAN><SPAN class="operator token">></SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Are you getting errors? What version of Pro are you using?
