target fields are mapped by field name, not by position in
the record.
Note that the generated flags in \a values are preserved
and determine whether the corresponding fields are used when
changes are submitted to the database. The caller should
remember to set the generated flag to FALSE for fields
where the database is meant to supply the value, such as an
automatically incremented ID.
Note that the generated flags in \a values are preserved to
determine whether the corresponding fields are used when changes
are submitted to the database. By default, it is set to \c true
for all fields in a QSqlRecord. You must set the flag to \c false
using \l{QSqlRecord::}{setGenerated}(false) for any value in
\a values, to save changes back to the database.
For edit strategies OnFieldChange and OnRowChange, a row may
receive a change only if no other row has a cached change.
