  1. Hi, I got FireDAC functionality working with the EMPLOYEE table. I wanted to load/save data using a json file for simple app config data, but as soon as I placed a TFDMemTable on the data module, I get an Access Violation when I request anything from that resource. (E.g. a GET on the original Employee table). The call stack says the a/v occurs in MARS.Data.FireDAC.TMARSFireDAC.InjectMacroValues(nil, True) which is in turn called from TMARSFDDataModuleResource.Retrieve. I have not changed any properties on the FDMemTable nor added any code. When I delete the component and recompile the server, the a/v goes away. This can be easily replicated using the FireDACBasic demo, by adding a TFDMemTable to the Server.MainData datamodule. Thanks for your help Stuart
  2. Hi, anybody had troubles performing a backup of a FB3 embedded database through the TIBBackup component? Firebird 3 uses fbclient.dll as client library also for embedded connections so it seems there's something wrong in the TIBBackup component when determining the client library to use (FireDAC.Phys.IBWrapper unit, TIBLib.GetLibraryInfo function. Given sLib var is always 'fbclient.dll' it misses it is a Firebird embedded connection). We tried to force fbclient.dll as vendor lib (giving a proper value to the DriverLink property of the TIBBackup instance, we also tried to set Embedded property of the driver link manually) but no way, it is always looking for fbembed.dll instead of the specified one (fbclient.dll). A quick and dirty workaround is to copy the DLL (fbclient) with the old name (fbembed) but I would like to avoid this, if possible. Any help would be appreciated. Maybe @Dmitry Arefiev may enlight us 😉 Thanks in advance

    Which type will hold better a TBCDField value?

    #Delphi, #FMX, #FireDAC. I have a DB Field defined as DECIMAL(15, 3); This produce permanent fields on my program of the type TBCDField. All of this is correct. Sometimes I need to Assign the value of one of this fields to a local or class variable. Which type do you recommend for this variable to assure I do not go to lost precision and the value is going to be near to an unaltered form?
