  2. Add DefaultFormat property to TIBCQuery for Date and Numeric fields.

    It would be nice to have more control over display formats for Date and Numeric fields.
    So having a DefaultFormats property like FIBPlus has, would be of great value.

    FIBPlus implementation:
    DefaultFormats: TFormatFields;

    TFormatFields = class(TPersistent)
    DisplayFormatDateTime:string;
    DisplayFormatDate:string;
    DisplayFormatTime:string;
    DisplayFormatNumeric:string;
    EditFormatNumeric:string;
    ....
    end;

  4. Transaction should be closed when TIBCQuery (DataSet) is closed, and Transaction was started by that component. Same as IBX TIBTransaction.

    When I use TClientDataSet + TDataSetProvider + TIBCQuery and I open the ClientDataSet and also the TIBQuery is opend and closed, but the transaction is automaticlally started but not closed. In a n-tier solution (e.g. DataSnap) I open the ClientDataSet in the the client but have no access to the underlying Query and Transaction which is on the server side.

    The TIBTransaction has that feature implemented and is very handy to use.

  5. DataSet memory Container

    My problem today.
    I developed a system that is going to be sold to many clients. The problem with firebird nowadays is that anyone can copy the database file and open it in its computer. Using SYSDBA and masterkey the database file can be opened in any computer and then, all your register can be copied.
    My dream would be that the user and password could be into the database file and not in the server. But I think this is so far away to come true.
    Then, I see a possibility to have all my strings rows encrypted, but…

  8. SaveToXml method from tIBCStoredProc or tQuery splited into several files

    Sometimes results is to big to be save or more often to be loaded into a tVirtualTable (not enough memory). Solution should be to split the result files into several smaller ones (according to line numbers or size).

  9. Extend TIBCLoader beyond event driven design when loading data.

    Currently TIBCLoader allows only to Load data by handling particular events. If I want to save something to database I need to handle OnPutData event. Unfortunately this solution requires usage of global variables because to know what I want to insert I need to look for some data beyond the scope of an event.

    Even the simple demo of yours shows this problem. You are using a global variable Count to know how much data you want to put it. Rest of the data you are using in a demo is random so it could be generated locally in the…

  10. Display Computed fields values and exclude from SQL Generator

    I really like to see a new option in the TIBCQuery component to display the computed field automatically like the option defaultvalues

    Also to exclude all the table computed fields from insert and update SQLs automatically when using the SQL generator tab in TIBCQuery so I dont get errors about modifying read only dataset

    This small enhancement but will boost development time

    thanks

  11. Eliminate parethesis when using AddWhere

    I would like complete control on how the parenthesis are added to the where clause. The way they are added now, it can result in a where clause that won't return what you're looking for.

  12. Add threaded module to connect and performce SQL operations inside thread

    Currently when I tried to perform some SQL operation like connect or use filtersql for table the db bound control flashes and I get many errors like "system out of resource" , etc...

    I wish to see IBDac add a new special module to use as a holder for the IBDac components. this module can work inside a second thread but at the same can be bound to the main thread VCL UI controls....is that possible ?

  13. IBDAC - is there multiple overlapping transactions support ?

    inidac page claims multiple transaction supports. IBDAC is rumored to be slcie of UniDAc but it does not claim overlapped and evenmere nested transactions support at http://www.devart.com/ibdac/features.html

    I think that should be stated clearly whether this feature been removed from IBDAC or stays there.
