The parameters in the tool properties list corrispond directly to the GetParameterAsText values. There is a second kind of cursor that can be used at version 10.1 and later; skip to the final step for that sample. The Input Table can be a feature class (including shapefile) or a table.. All fields in the Input Table will be kept during the join.

Attachments are only extractable if the output data format is a file geodatabase and the extract method is set to Select Features. The Expression parameter can be created with the Query Builder or simply typed in. Floating point attribute values are written to the text file with six significant digits. You'll more less just have to tell the tool where the script is and then setup each parameter with a name and the appropriate data type. In the selection method, you first select features from a larger data set, then export those selected features to a data file. When exporting lines or areas to a CSV file, only non-spatial attributes are extracted. Below are the general steps for the procedure followed by code examples using a zip code polygon shapefile. In this article we’ll examine how you can use Python with Arcpy and Numpy to create a list of unique attribute values from a field. This is sort of a continuation of my previous post. 001,003,005...) If the table to table way doesn't work, any suggestions would be helpful. '''This code will export the attachments associated with a feature class features into : a folder naming output files using the feature's attribute provided''' import arcpy: import os: ##define input parameters for the tool: #input attachments table: in_table = arcpy. import arcpy arcpy.SelectLayerByAttribute_management("states", "NEW_SELECTION", "[NAME] = 'California'") SelectLayerByAttribute example 2 (stand-alone script) The following stand-alone script shows how to use the SelectLayerByAttribute function in a workflow to extract features to a new feature class based on location and an attribute query.

This page from the help document should help (the other pages from that section may be useful too). Construct a loop that runs all the needed processes on each value from the field, in this case, Select Layer by Attribute and Select Layer by Location. I got the getparameterastext() part. workspace = "c:/data/mexico.gdb" # Make a layer from the feature class arcpy. I guess my problem is the creating the tool part. This step is completely contained within the loop. The rest of your code should work the same but you will use the variables in place of the 'hard coded' values. On the sqlclause portion, how do I get it to loop through the list with a different parameter each time. Creating a New Layer from Selected Features In using ArcGIS, we found that it was overly complicated to create a new layer from a selection of features. The following are 7 code examples for showing how to use arcpy.SelectLayerByAttribute_management().These examples are extracted from open source projects. Build another search cursor within this loop to iterate through all the values associated with the rows found in the Select by Location process and write those values in the text file. If it does not already exist, Python will create it in this step. Set up the environment and define needed variables: Convert the input shapefile into a Feature Layer, so it can be used in the Select Layer by Attributes and Location tools.

Instructions provided describe how to select a feature by an attribute, select all the features that share a boundary with it, and then export the values of all of the features to a text file. If a layer is used for Input Features and no expression is entered, only the selected features are written to the output feature class. ... Model builder can export the algorithm in Python scripting as well. For practical purposes just say that the main file that I am pulling the data out of is called "Customers" and I would like to export the individual years into new shapefiles called "Customers_20xx". Select the polygons based on the attribute using the function available under Selection Menu / Select by attribute. For instance, on the list portion of my code.
