there a way to reduce the time for the
ExecSql?
You must prepare the desttable query before starting the loop.
Then it does not need to prepare/unprepare.
the faster way is using a foreign table definition in Postgres, though.
You can then do the copy w
rew/lib to the link search
path.
So good to go.
For next release can we change the gmp.pas source to:
{$ifdef darwin}
{$linklib gmp.dylib}
{$endif}
Done.

It seems to be a windows-specific problem. Here is the result of your
program when executed on Linux:
Const_Ans1 = 2.85714298486709594727E-0001
Var_Ans1 = 2.85714298486709594727E-0001
As you can see, the result is identifical.
As for the explanation, I will have to leave that to the comp
ant type to use.
(incidentally, this is one of the reasons the FPC team does not want to make
inline variables as Delphi does, since there the type will again be determined
by
the compiler - just as for constants, leading to ambiguity...)
