How to use query in arcpy.Append_management

[deleted-user-yC5VkbyXzrQR]

it's weird that the arcpy.Append_management function does not have any arguments for SQL Expressions. 

Does anyone know a way around this ? 

Below is my code. Basically I want to take a feature layer with a sql statement and put it in a sde. 

Would I have to use arcpy.MakeFeatureLayer_management() then append? 

And I want to ensure that the expression only grabs 1 feature, if there are more than 1 features trying to append it will fail. Would I do this in the validation or could I do this in the script ?

Hi Adam,

Would I have to use arcpy.MakeFeatureLayer_management() then append? 

Yes, this correct.  You will then pass the Feature Layer as the input for the Append.  Before doing so you can execute Get Count function and only run the Append if the count is equal to one.  Ex:

arcpy.MakeFeatureLayer_management(fc, "fLayer", "OBJECTID = 1")
result = arcpy.GetCount_management("fLayer")
count = int(result.getOutput(0))

if count == 1:
    arcpy.Append_management("fLayer", target",....)‍‍‍‍‍‍

Thanks Jake. 

Thats exactly what I did. It worked!
