Changing the default merge rules for fields in Spatial Join

Discussion created by pasquale.lanera on Jan 26, 2013
I have a problem with a Spatial Join in a Model.
The join features is a feature class with many fields and I have to change the merge rules for many numeric fields, about 30, from "First" (default value) to "Mean" and it is a long time procedure.
There is a procedure (a script or others) to change in my Model all the numeric field merge rules in "Mean" in one go ?
Or is it possible to chenge the merge rules defoult value from "First" to "Mean"
Or could be set the merge rules like a variable from a parameter in the Model ?
