Re: [Lazarus] TFMTBCDField problem
I am almost convinced that the problem is not what i am seeing...this code works if VSQLVar^.sqlscale = 0 then i := AParams[ParNr].AsIntegerelse//i := Round(AParams[ParNr].AsCurrency * IntPower10(-VSQLVar^.sqlscale)); i := Round(BCDToDouble(AParams[ParNr].AsFMTBCD) * IntPower10(-VSQLVar^.sqlscale)); the reason i think that this is not a *real* fix, is that the TParam.asCurrency returns a Varriant and this raises the error, but TParam.AsFMTBCD returns a TFMTBCD Value converted from a variant! This *should* raise the same error, but it doesn't How could i have debug info in FMTBCD unit? i would like to take a look at this BCDFactory PS : I am really trying to fix the problem and not just patch around it, i have the highest hope in your understanding and help :) Regards,Chris On Sunday, November 9, 2014 12:08 PM, Joost van der Sluis jo...@cnoc.nl wrote: On 11/09/2014 03:37 AM, Chris Rempas wrote: I copied the binaries that were missing in my FPC 2.7.1 from FPC2.6.4 i run make clean all and make install again and VOILA! i have debug! :))) (it seems all the binaries must be in the same directory for some reason) I don't really understand which binaries you did copy. But I'm glad you have the debug-info. FILE dsparams.inc, LINE 519 Function TParam.GetAsCurrency: Currency; begin If IsNull then Result:=0.0 else Result:=FValue; 519 end; For 'BCD' fields, the Currency type is used. In your case you have 5 decimals, so you can not use .AsCurrency... when the parser gets the values of the params, this param is BCD and as you can see it tries to get it as currency In a quick check, methods [AssignToField] [AssignFromField] [GetData] [SetData] are not fully ready for every FDataType some are missing BCD Fields, some are missing FMTBCD Fields and sometimes it gets the same treatment as Currency... Currency and BCD are the same. So apparently support for FMTBCD fields is missing here. As the FMTBCD support is relatively new this could just be missing. I am guessing at this point that i don't have the latest code if i could have a copy of the latest component, i would be able to test and maybe help debug with real testing 2.7.1 is the latest version? Yo have to find out where/why the FMTBCD param is accesses as AsCurrency (Assign, GetData, SetData?), and fix that. Then you can simply recompile fcl-db and see if your program works. Oh, and if you have fixed the problem, send us a patch. ;) Joost. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

That's really strange. Here it works, and also the testsuite has some
tests for this.
What you could do is build fcl-db with debug-info. Search for the fcl-db
sources (packages/fcl-db). Open a command-line (powershell) and make
fcl-db the current directory. Then do 'make clean all OPT=-gl'. And then
do 'make install'. Note that it could be that you have to run pwoershell
as administrator to be able to do a 'make install'.
Now rebuild your application and try again. Now you should be able to
see where the problem arises, and get some more information using the
debugger.

Joost.
