Configure Attribute - Attribute Expression

Calvin_GIS — Fri, 25 Mar 2022 04:11:11 GMT

HI ESRI Community,

I am very new to Arcade expression and is seeking for assistance. I am hoping to create something like:

IF $feature A is <= 75000

then $feature B = "Yes"

IF $feature B is => 75001

then $feature B = "No"

Looking forward the solutions.

Also seeking for doco and video to improve my coding skills.

Thanks 🙂

// Calculation Attribute Rule on your feature class // field: B // triggers: insert, update return IIf($feature.A <= 75000, "Yes", "No") // if condition is true, then "Yes", else "No"

The ArcGIS Developer page for Arcade is a good place to start:

Getting Started | ArcGIS Arcade | ArcGIS Developer

I find the function reference especially important, this is a page that I have bookmarked:

Function Reference | ArcGIS Arcade | ArcGIS Developer

If you want to play around, you can do so in the Arcade Playground:

If you're looking for examples, there is a Github with Arcade expressions for diffferent profiles:

Legend! Thank you so much for your help. Sorry to be a pain but I am just wondering what would the syntax if it's between 1 to 75000?

Then you use a logical AND to concatenate the conditions (A >= 1 AND A <= 75000)

return IIf($feature.A >= 1 && $feature.A <= 75000, "Yes", "No")
