Question

I’m working on an application that requires the following regional settings (Delphi 7 and PostgreSQL 9.0):

   1. DateSeparator:='/';
   2. TimeSeparator:=':';
   3. ThousandSeparator:=',';
   4. DecimalSeparator:='.';
   5. ShortDateFormat:='MM/dd/yy';
   6. ShortTimeFormat:='hh:mm:ss';

I need to change the regional setting only for my application and not system wide.

In OnCreate of the form I set the above separators, and
my current system separators are:

   1. DateSeparator='|';
   2. TimeSeparator='|';
   3. ThousandSeparator='|';
   4. DecimalSeparator='|';

(This is for the test purpose.)

Now in Postgres I have a table from where I get dates to display in my application but somehow the dateseparator doesn’t seem to work (as seen in label1)!

Check the image.

I fire a query to get the dates from the table

                    Label1.Caption:=(Fields(1).Text);
                    Label2.Caption:=datetostr(Fields(1).Data) ;

The query is

 select min(dat), max(dat) from diary where survey in (2008401) and event not in ('E','C','R') and region=6100;

now the same date if I take as .data differ in the date separator from .text dateseparator
why this is happening?

Why are the regional settings not applied to label1.caption (as shown in the image)?

Answer 1

ok i found on one site
enter link description here
for getting the appropriate format all i had to do was get the fire the query as

select to_char(min(dat),'mm/dd/yy'), to_char(min(dat),'mm/dd/yy')
from diary
where survey in (2008401) and
event not in ('E','C','R') and region=6100;

This gave me the proper result in the format i wanted
