Hi All,

I hope someone can spot why i cannot get a result of a search in
ewb2/dbisam.

Dataset "tider" -> points to a dbisam table containing 2 fields, timerid
(autoinc), time (timestamp)..

Sample data from table:

Timerid,Time
=========
1,00:00:00
2,00:15:00
3;00:30:00

etc..

Code in ewb:

FormatSettings.DateSeparator := '-';
FormatSettings.TimeSeparator := ':';
FormatSettings.ShortDateFormat := 'dd-MM-yyyy';
FormatSettings.ShortTimeFormat := 'HH:mm';

   with Tider do
      begin
      Columns['Timerid'].SortDirection:=sdAscending;
      SortCaseInsensitive:=True;
      SortLocaleInsensitive:=True;
      Sort;
      InitFind;
      Columns['Time'].AsTime:=strtotime(StartTidEdit.Text);
//      Columns['Time'].AsTime:=strtotime(StartTidEdit.Text + ':0');
//      Columns['Time'].AsTime:=strtotime(StartTidEdit.Text + ':00');
      if Find(False,True) then begin
         Aktuelstarttid := Columns['Timerid'].AsInteger;
         Result:=True;
      end
      else
         Result:=False;
      end;

Does initfind not work with timestamp fields or?

Thanks in advance.

Hüseyin A.

I don't know anything about this, but my first check would be what this
actually gives you. Does strtotime give you a small number, or the
local time which includes "today"? Not clear from the help, and I
suspect it is "2pm today" rather than a generic 2pm. You need the
latter to match your table, I think?

Hi Matthew,

Showmessage(StartTidEdit.Text) returns 00:30 and does not find any
records in table, but following does not work either:

//      Columns['Time'].AsTime:=strtotime(StartTidEdit.Text + ':0'); ->
returns 00:30:0
//      Columns['Time'].AsTime:=strtotime(StartTidEdit.Text + ':00'); ->
returns 00:30:00

Yes, i need to get the timerid of the table where time are selected by
user from a dropdown box. Kind of dblookupcombox function like in delphi

Hüseyin

It would, but that isn't what you are setting the field to. You are
setting it to strtotime('00:30'). Do a showmessage on the integer value
that this returns. If it is under 10,000 or so, I'd think it right. If
it is a few billion, then it is "today".

If your field is timestamp then where is the date portion ?

"00:30:00" is not what i would call a normal timestamp field in dbisam
(looks lie time fieldtype to me).

Either way these will get translated into EWB date type which is NOT
same is dbisam - its integer from approx 1970.

If you're just entering '00:30' then yes nothing will be found.

Just do this and see what you get back :

ShowMessage( DateTimeToStr(strtotime('00:30')));

In my case i'm seeing '31-12-1969 00:30' since EWB has to supply the
date portion.


> Does initfind not work with timestamp fields or?

Yes it does - you have to provide a properly formatted EWB datetime.

In my test table i have a time type data field which contains "00:30".
In EWB side this is represented as -2209159800000 or as UTC foramtted
string it is  "30-12-1899 00:30".


So assuming user just enters the time (i.e. '00:30') i could construct a
datetime as

StrToDateTime('30-12-1899 ' + StartTidEdit.Text,true)

and then Find should find your record just fine.

Raul,

You are correct, it was not timestamp but time that was the field type
(can see now i could use another name for the fieldname as it's the same
as the type)

Matthew,

See my reply to Raul, it was my mistake, the field type is time and not
timestamp.
