Extracts the fields to save to the database from the objItem.SaveFields function. The fields are then written to the database using either an SQL INSERT or UPDATE depending on whether the object has already been saved. If the collection has implemented IDatabaseObjects.KeyFieldName then objItem's key is also validated to ensure it is not null and unique within the collection. If objCollection has implemented IDatabaseObjects.Subset then objItem should exist within objCollection. If not, a duplicate key error may occur if the obItem's key is being used in another subset in the same table. If a record is being amended (IDatabaseObject.IsSaved returns true) then the function will "AND" the collection's IDatabaseObjects.Subset conditions and the objItem's IDatabaseObject.DistinctValue value to create the WHERE clause in the UPDATE statement. Therefore, the combination of the IDatabaseObjects.Subset and IDatabaseObject.DistinctValue conditions MUST identify only one record in the table. Otherwise multiple records will be updated with the same data. If data is only inserted and not amended (usually a rare occurance) then this requirement is unnecessary.
