If I recall correctly, if you set the property "Ignore CSV Header Column
Names" to true, then it'll take the columns in the same order as defined in
Same on the DB side (PutDatabaseRecord), with the property "Translate Field
Names". If false, the field names must match the column names exactly, or
the column will not be updated. If true, I think it'll assume that fields
in the input are in the same order as in the database.
Someone more familiar with PutDatabaseRecord can chime in to correct me :)
