  1. TUniLoader with Firebird - automaically calulate maximal value for RowsPerBatch

    For Firebird the possible value for RowsPerBatch depends on the number of rows in the table because the maximal length of an SQL statement is 64KB.
    For RowsPerBatch=0, UniDac should calculate the maximal possible value itself.

  3. Allow Joined tables' columns to be updated in TDBGrid, as ADO allows

    When using TADOConnection / TADOQuery to create datasource for TDBGrid, columns from main tables as well as joined tables may be edited in the grid. With TUNIxxx components, only the first table in the query can have its columns updated in the grid.

  4. TUniMetaData data-types

    the TUniMetaData data-type field now returns different data for different databases - Example:
    currently for MySql it returns a string e.g. 'float'
    but for MS SQL server it returns a number: e.g. 5 (for float fields)

    so the recommended improvement is to add a new field to the result that returns a string representing the native database type.

    this feature is useful if you want to show a list of columns including data-types to the user - it can also be used to generate a create script, etc.

  5. dbMonitor shows string fields as <BLOB:19> Should show the actual data

    dbMonitor, which is a great feature, shows any string values as <BLOB:19> instead of the actual data in that field. This might only apply to postgresql

  6. Migration Wizard (Strip the .DB from tablenames if Paradox)

    When converting from Paradox to SQLite, I ran into 2 problems.
    1) the TableName.DB I used in paradox does NOT have a .DB ending in the actual tablename...
    2) The data module where the "database1" was declared for the TUniConnection was not included in the files, and then the connections were not set to them. I had to open all the forms and remove the .db and set them

    I think that the Migration Wizard should handle those better...

  15. UniDac should support ElevateDb

    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.

  17. Create UniAlerter support for DB2

    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.

  19. Native driver for Filemaker Server database

    The only way to access a Filemaker Server database is via ODBC, which is not supported in iOS. There is a large installation of Filemaker databases out there, backed by Apple, and with the increasing market share of Mac, iPad and iPhone, it will likely gain in popularity.
