I really only used the template table for the field names. You could easily just put the field names in a list variable instead of calling list fields on the template table. ... View more

No, you're correct, arcpy.da.Walk() would probably be the best thing to use. I am so used to using it just in a geodatabase that I forgot that it listed folders too. ... View more

You could put your particular subdirectories in a list. Then you could add the shapefile copy loop code that forest knutsen wrote inside a loop that iterates through the subdirectory list. rootdir = r"C:\xxx\xxx\shp" subfolders = [     "Folder1",     "Another Folder",     "AndAnother", ] for folder in myfolders:     arcpy.env.workspace = os.path.join(rootdir, folder)     for shapefile in arcpy.ListFeatureClasses():         print 'copying: ' + shapefile[:-4]         arcpy.CopyFeatures_management(shapefile, os.path.join(out_path, shapefile[:-4])) Or you could utilize Python's own os.walk() to navigate your folders instead of listing them out. ...

My first thought is to use Python and arcpy.AddField_management(). This assumes all the fields are the same type and length. If they are all different, it can still be done but the code would have to be changed a bit. import arcpy testtable = r"C:\temp\mygdb.gdb\Test" newfields = [     "Test1",     "Test2",     "Test3",     "Test4",     "Test5" ] for field in newfields:     arcpy.AddField_management(         testtable,  ## in_table         field,  ## field_name         "TEXT",  ## field_type     )     print "{} added".format(field) ...

Well, I didn't end up using any joins after all! Like you mentioned, it was always writing the fields from both feature classes and I got tired of fighting with it. Here's my solution: def main():     import arcpy     import os     # Local variables     sourcegdb = r"C:\temp\83629_Baseline.mdb"     panels = os.path.join(sourcegdb, "AllSignPanels")     supports = os.path.join(sourcegdb, "SignSupports")     template = os.path.join(sourcegdb, "SignPanelTemplate")     # Get all SupportIDs for where clause IN() statement     supportid = tuple(i[0] for i in arcpy.da.SearchCursor(supports, "SupportID"))     # Optional truncate     arcpy.TruncateTable_management(template)     # Retreive only panel records that have a support and write to output table     fields = [f.name for f in arcpy.ListFields(template)]     where_clause = "SupportID IN{}".format(supportid)     with arcpy.da.SearchCursor(panels, fields, where_clause) as s_cursor:         with arcpy.da.InsertCursor(template, fields) as i_cursor:             for row in s_cursor:                 i_cursor.insertRow(row) if __name__ == '__main__':     main() Since you had that nice SignPanelTemplate table, I just used that for the field names. If you want to overwrite the table each time, just truncate the table before you start writing the rows again. ... View more

To Mody Buchbinder‌ Running compress on Linux/Unix We have ArcSDE in Oracle 11g on a Linux server. We perform database maintenance operations (including compress) with a Python script executed by Task Scheduler on a Windows Server 2012r2 machine. We use a process very similar to the one Esri recommends‌ and it works quite well; no SDEMON required. However, we did find that killing all users did not clean up the processes and sessions correctly on the Linux server. See my thread here for more information. ... View more

If you feel like posting some sample data we can look at how to get this working the way you want. ... View more

There is nothing special you have to write to the file to close it, but you do need to close the CSV open object in the code. If you have it in a with statement (like in my code) it will always close automatically. In the code you posted, you do not have it in a with statement so you need the f.close() at the end. Glad you got it working. Keep in mind that when you open the CSV file for writing, you have different modes to open it as. Use 'r' when the file will only be read, 'w' for only writing (an existing file with the same name will be erased), and 'a' opens the file for appending. Any data written to the file is automatically added to the end. The mode argument is optional; 'r' will be assumed if it’s omitted. If you try using the append mode, make sure you don't write the field name header row again! ... View more

I don't know what outLayerFile is so this is the best I can do for you. See if you can make this work. import arcpy import os import csv lyrFile = arcpy.mapping.Layer(outLayerFile) for lyr in arcpy.mapping.ListLayers(lyrFile):     if lyr.name == "Routes":         # Create CSV         CSVFile = r'F:\Workspace\Sandy\GM_costAnalysis\analysis2\allRoutes.csv'         with open(outputCSV, "w") as csvfile:             csvwriter = csv.writer(csvfile, delimiter=',', lineterminator='\n')             ## Write field name header line             fields = ['OrderCount', 'TotalTravelTime', 'TotalDistance', 'Block', 'Scale']             csvwriter.writerow(fields)             ## Write data rows             with arcpy.da.SearchCursor(lyr.dataSource, fields) as s_cursor:                 for row in s_cursor:                     csvwriter.writerow(row) ...

After further investigation, I should clarify that the feature class needs to be a feature layer before you can do the join. Once you do the join, the field names on the feature layer are indeed "featureclassname.fieldname". ... View more

After further investigation, JoinFields might be a better option since you can specify fields you want. And to clarify, if using a feature classes, you have to make a feature layer first before doing the join. After the join is done, field names will be like "feactureclassname.fieldname". ... View more
