I am trying to do a SQL dump of a table to excel but I can't get past the error, what am I doing wrong? Error line 14 'utf8' codec can't decode byte 0xc3 in position 0: invalid continuation byte import pyodbc

I was able to figure it out and it wasn't as complicated as I thought. if int(arcpy.GetCount_management("Parcels").getOutput(0)) > 0:
arcpy.Select_analysis("Parcels", "SelPar")
unique_values = set(row[0] for row in arcpy.da.SearchCursor("SelPar", "Field"))
format1 = ("_".join(unique_values))
Name = format1
for elm in arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT"):
if elm.text == "Par Text":
elm.text = Name

Working with Arcmap 10.6 and ArcToolbox script, I would like to select polygons and pass the attributes of a field of those selected polygons to arcpy.GetParameterAsText , I would then pass the arcpy.GetParameterAsText to update the TEXT ELEMENT of arcpy.mapping.ListLayoutElements to something like R2875103700_R2875103600_R2875300000_R2829301100. Is this possible if so how?

I am working with a table that I am making trying to query and take the features that are selected from the query to a new layer/feature class but I am not sure why it is not working. I don't get any error's, using Python 3.6.8. I have tried Copy features and Table to geodatabase conversion but nothing gets created. env.workspace = r"D:\Temp\temp.gdb"
origin_table = "LV"
Clause = "group_code IN ('01','02','03','05')"
arcpy.MakeQueryTable_management(origin_table, "tmp_view", "NO_KEY_FIELD", "", "",Clause)
arcpy.TableToGeodatabase_conversion("tmp_view", r"D:\Temp\temp.gdb")
#arcpy.CopyFeatures_management("tmp_view", r"D:\Temp\temp.gdb\LV_1")

I was able to get to select features with the following but i was trying to use the arcpy.da.SearchCursor . sql = "[Shape_Area] in (SELECT max([Shape_Area]) FROM fc2 GROUP BY [PIN])"

My bad, Arcmap and would be using arcpy.SelectLayerByAttribute_management not ByLocation. I have tried the following I don't get an error but nothing is selected sql = "select MAX(Shape_Area) from fc group by PIN"
with arcpy.da.SearchCursor(fc2, ['SHAPE@']) as cursor:
for row in cursor:
arcpy.SelectLayerByAttribute_management(fc2,"NEW_SELECTION", sql)

Something like below but It might just be easier to use the Use append tool to append your selected features including all attributes. import arcpy
from arcpy import env
fc1 = "" #Feature class to copy from
fc2 = "" #feature class to copy to
arcpy.env.workspace = "" #Workspace "C:/Temp"
arcpy.env.overwriteOutput = True
# Start an edit session. Must provide the worksapce.
edit = arcpy.da.Editor(arcpy.env.workspace)
# Edit session is started without an undo/redo stack for versioned data
# (for second argument, use False for unversioned data)
edit.startEditing(True)
# Start an edit operation
edit.startOperation()
arcpy.Append_management(fc1, fc2, "NO_TEST")
# Stop the edit operation.
edit.stopOperation()
# Stop the edit session and save the changes
edit.stopEditing(True)
arcpy.RefreshActiveView()

Can you elaborate a little more on what you are trying to accomplish, are you trying to copy all the points from one feature class to another or just copy the selected ones or ones with a certain attribute?

Got it to work with making a feature layer. and adding row 10 lyr = r'C:\Temp\TaxParcels.shp'
subs = r'C:\Temp\SubsOutsideCities_Temp.shp'
arcpy.MakeFeatureLayer_management(lyr, "parLyr")
with arcpy.da.UpdateCursor(subs, ["VxCount", "Shape@"]) as cursor: # cycle through outer polygon layer
for row in cursor:
arcpy.management.SelectLayerByLocation("parLyr", "HAVE_THEIR_CENTER_IN",row[1]) # row[1] is SHAPE@
count = int(arcpy.GetCount_management("parLyr")[0])# row[0] to be updated with count
row[0] = (count)
cursor.updateRow(row) # update row

If i run the following in stand alone python, every value in VxCount1 has the same number. subs = r'C:\Temp\SubsOutsideCities_Temp.shp'
lyr = r'C:\Temp\TaxParcels.shp'
with arcpy.da.UpdateCursor(subs, ["VxCount1", "Shape@"]) as cursor: # cycle through outer polygon layer
for row in cursor:
arcpy.management.SelectLayerByLocation(lyr, "HAVE_THEIR_CENTER_IN", row[1]) # row[1] is SHAPE@
row[0] = int(arcpy.GetCount_management(lyr)[0]) # row[0] to be updated with count
cursor.updateRow(row) # update row

Randy I was able to get to work, thanks for the help. import arcpy
mxd = arcpy.mapping.MapDocument("current")
df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]
lyr = arcpy.mapping.ListLayers(mxd, "Taxlots")[0]
subs = arcpy.mapping.ListLayers(mxd, "SubsOutsideCities")[0]
#arcpy.MakeFeatureLayer_management(par, "parLyr")
with arcpy.da.UpdateCursor(subs, ["VxCount1", "Shape@"]) as cursor: # cycle through outer polygon layer
for row in cursor:
arcpy.management.SelectLayerByLocation(lyr, "HAVE_THEIR_CENTER_IN", row[1]) # row[1] is SHAPE@
row[0] = int(arcpy.GetCount_management(lyr)[0]) # row[0] to be updated with count
