hi,
i'd like to make a calculation field from arcgis Rest services directory (from AGOL) with a concatenation from 3 fields.
i've tried many things, but not one worked.
here is what i want to do: put field1 + field2 + field... in the field "conc_hors_CCM".
Many thank if you give me a solution.
I'm novice in SQL expression for information...
Just to precise that is from Arcgis online feature service
Assuming your where statement is correct, try this statement in the update box (note the use of double quotes around the expression and not the field names):
[{"field" : "conc_hors_CCM", "sqlExpression" : "code_mag1 + code_mag2"}]
Regarding the where statement, is "concatenation" a field name?
Hi,
works perfectly!!!
thank you very much. i definitly have to learn sql expression !
Yes, concatenation is a fieldname.
