  2. Currently such options as FetchAll, QueryRecCount, and others can be set for each DataSet separately. If you need to change these settings, you need either to do it manually at design-time or set them in cycle for all DataSets at run-time.

    We may add an option to set these values for all DataSets for a connection. For example, if FetchAll is set to True for a connection, all DataSets in this connection will use this value. You need to set this property only for those DataSets, that must have different value of this option.

  3. You should implement a feature to avoid moving a lot of records over the network. The components should keep a record position pointer.
    So if a dbgrid is 20 lines (the system should read only 20 records en send 20 records over the internet of lan. At next page, read the next 20 records and at page back read the 20 previous records.
    It is a feature that is present in ElevateDb and Anydac.
    I am very happy with your components and I know we can set the number of records to return, but the described option should be a…

  9. When using mySQL as the provider it is possible to add drop and create table statements to the "backuptofile"-file. This option is not possible when using the Microsoft SQL server provider. Could you please add this option ? :-)

  14. PostgreSQL 9.2 has a new feature that allows results sets to be returned row by row instead of the whole result set at once.
    This is a huge improvement for larger result sets.
    See here for more info:

  15. FillFieldsDefaultValues (in TCustomDADataSet.DataEvent) procedure is called everytime for a dataset, if Options.DefaultValues is True. It creates a query to get the default values. It might be a good idea to cache the defaults and avoid the query.

  16. ElevateDb is a powerful embedded and C/S database and should be supported by Unidac. It has been around for years and has many features found in PostgreSQL, like bi-drectional replication.

  20. UniAlerter - is a component to receive notifications from DB server.
    Currently UniDAC supports Interbase, Oracle and PostgreSQL in UniAlerter.
    It will be great if UniDAC could support IBM DB2 (module DBMS_ALERTER) in UniAlerter component.
