This parameter is only valid when the spatial relationship is specified ( Match Option is set to Closest or Closest geodesic ). The value of this field is -1 if no feature is matched within a search radius. If no field name is provided, the field will not be added to the join.If a data path is used, the layer will be created with the join. The join will always reside in the layer, not with the data. To make a permanent join, either use the Join Field tool or use the joined layer as input to one of the following tools: Copy Features, Copy Rows, Export Features, or Export Table.If the field already exists, and you run arcpy.AddField_management() for that same field, it will do nothing.

I don't think there is a page mapping parameter types. As you are developing an arcpy toolbox, stick to the naming conventions used in the geoprocessing tools as they only accept those. You just have to assume that your users are savvy enough to realise "Text" is "string" and vice versa.Interesting: When I'm going to add those fields sequentially using arcpy.AddField_management everything works as expected. Unfortunatelly this is not an option, since I'm going to add a lot of fields to that table (more than 40), which costs a lot of time when I'm doing it field after field (more than a hour per table!)tbl = arcpy.da.FeatureClassToNumPyArray(dg, ave_fields) print sum(tbl[0]) # this allows me to sum a row within the array #now i loop through each row and sum the values within the array, and return this value in the weekly_ave field for each row with arcpy.da.UpdateCursor(dg, "Weekly_Ave") as ucursor: for urow in ucursor: print sum(tbl[0 ...An overview of ArcPy functions.
