tfieldlink updates a field value (typically to initialize it on insert) in onupdatedata; ttimestampfieldlink is a descendant that sets a field to the current timestamp before post. See also tfieldfieldlink, to update a field from the value of a field in another dataset (e.g. to copy a master key into a new detail record), and tfieldparamlink (unit msesqldb), to feed a field value into a query parameter of another dataset — useful for a server-side lookup, or for master/detail filtering.
