get field valule and calculate field in modelbuilder

[soniaS]

Hello,

I'm using ArcGIS Pro V 2.8.1

I'm trying to make a modelbuilder with thoses steps :

1) get a geodatabase in a folder

2) get a specific table in this geodatabase

3) get a field value from an other table (with a test condition)

5) calculate a new field with calculate field (it's a text field), and fill it with the get value function

  So, my problem is that the calculate field function doesn't fill the table with the selected value.

when I select the data type " string" in the get field value, I have this error;

but when I select the data type " field",  in the get value, I dont have errors but the new field in my table is empty.

Thanks for your help!

The Get Field GP tool only returns the first row according to the ESRI documentation (Get Field Value (ModelBuilder)—ArcGIS Pro | Documentation). If you are trying to copy a field value from one table to another I believe you need a common ID field to join the tables together before you perform the field calculation.

Hello, thank you for your answer,

Indeed, I was trying to retreive a value from an other table in order to add this value in a field, ( the same value for all features, as the calculate field does).  In fact, my goal is to realise a join with those tables and on this common ID field after this step. So thanks to your answer, gess that it is not the good method.

Maybe do you know a good way to add a value from an other table in a new field ?

Thanks a lot!
