Delphi工作笔记

 当对查询出来的数据进行修改时

delphi 的Dataset.RecordStatus会记录对当前数据状态

TRecordStatus = (rsOK, rsNew, rsModified, rsDeleted, rsUnmodified, rsInvalid,
    rsMultipleChanges, rsPendingChanges, rsCanceled, rsCantRelease,
    rsConcurrencyViolation, rsIntegrityViolation, rsMaxChangesExceeded,
    rsObjectOpen, rsOutOfMemory, rsPermissionDenied, rsSchemaViolation,
    rsDBDeleted);

批量更新时可对数据进行筛选再进行更新操作
