How to Rename Fields

[oknotsen]

Could you please give an example of what you are trying to achieve?

Please include example data / source data.

[maxgro]

TableA:

load

  rowno() as field1,

  rand()*100 as field2,

  1 as field3

AutoGenerate  100;

if you stop the script here you get

FieldNameMap:

Mapping Load * inline [

OldFieldName, NewFieldName

field1, newfield1

field2, newfield2

];

Rename Fields using FieldNameMap;
