Re: Firebird + empty strings, a problem

No problem and thank you for your work. Mormot souce code has since been modified to take this into consideration i.e. it checks the Len parameter in order to determine if string is actually empty so a Mormot example would no longer show a problem, but I think it's still worth making a change in Zeos.

Re: Firebird + empty strings, a problem

Can an admin move this to 7.2 please?

Also I can provide a sample project if needed, using Mormot, but not using zeos because I am not familiar enough with how it works sorry.

Re: Firebird + empty strings, a problem

Which function did you test?

GetPAnsiChar function that doesn't have Len parameter fixes the problem within itself by doing

Code: Select all

  ZSetString(P, Len, FRawTemp);
  Result := Pointer(FRawTemp);
but the one that does have Len param leaves the string content as-is.
