I am working on updating an outdated database with extension db1, which was created in 2002. But the problem is I can access the structure of this database to create a new one to work with a program that I use it.

as you can see I can't open it correctly. Is there any way to open this file .db1 and update it for this year 2022??
I have this program to access DB and check the data as you can see the rows, and column.
I'm trying to get an array with the following output:
["", "7", "02156567848", "CORTIER EP. ENGERANT ROSE JOSE MARIE", "059 NOMBRE DE LA PERSONA ES DIFERENTE"]
But using next code the result is different, because split is considering any non word character to separate the strings.
a = " 7 02156567848 CORTIER EP. ENGERANT ROSE JOSE MARIE. 059 NOMBRE DE LA PERSONA ES DIFERENTE"
b = a.split(/\W\W+/)
p b
Output:
["", "7", "02156567848", "CORTIER EP", "ENGERANT ROSE JOSE MARIE", "059 NOMBRE DE LA PERSONA ES DIFERENTE"]
Any idea how to solve this?
Thanks and regards!
Split on \s{2,} -- two or more white-space characters.
a = " 7 02156567848 CORTIER EP. ENGERANT ROSE JOSE MARIE. 059 NOMBRE DE LA PERSONA ES DIFERENTE"
a.split(/\s{2,}/)
# => ["", "7", "02156567848", "CORTIER EP. ENGERANT ROSE JOSE MARIE.", "059 NOMBRE DE LA PERSONA ES DIFERENTE"]

I extracted SIFT features from two videos to make a matching.
I need to compare each of the second video features with those stored in an array of features of the first video. I'm having trouble set the code so that when I have the correspondence I can get the frame in which the feature is present. How can I do? Can anyone show me a code example?
This is my code:
obj = VideoReader('video2.avi');
lastFrame = read(obj, inf);
numFrames = obj.NumberOfFrames;
%estrazione frame e sift
for k = 1 : 3 % numFrames / 5
disp(['Processing frame #', num2str(k)]);
this_frame = read(obj, k * 5); % leggi solo un fotogramma ogni 5 per velocizzarle la cosa
this_frame = imresize(this_frame, 0.5); % rimpiccioliamolo per questioni di efficienza!
I = single(rgb2gray(this_frame)) ;
[f,d] = vl_sift(I); % estrazione feature
features{k} = f; % salviamo le feautre e i relativi descrittori in delle celle
descriptors{k} = d;
end
save('feature_input', 'features');
save('descrittori_input', 'descriptors');
%%% un esempio di come ripescare i dati...
pippo = load('feature_input');
newfeat = pippo.features;
pippo = load('descrittori_input');
newdesc = pippo.descriptors;
for k = 1 : 3
disp(['Le feature del fotogramma', num2str(k), ' sono: ']);
f = cell2mat( newfeat(k) );
f(:, 1:10) % ne mostriamo solo un pezzetto... le posizioni delle prime 10 features
end
obj2 = VideoReader('video2u.avi');
lastFrame = read(obj2, inf);
numFrames = obj2.NumberOfFrames;
%estrazione frame e sift video2
for k2 = 1 : 3 % numFrames / 5
disp(['Processing frame #', num2str(k2)]);
this_frame2 = read(obj2, k2 * 5); % leggi solo un fotogramma ogni 5 per velocizzarle la cosa
this_frame2 = imresize(this_frame2, 0.5); % rimpiccioliamolo per questioni di efficienza!

[f2,d2] = vl_sift(K); % estrazione feature
features2{k2} = f2; % salviamo le feautre e i relativi descrittori in delle celle

You are matching using [matches, scores] = vl_ubcmatch(d, d2, 1.5) ;. d contains only the descriptors of the latest frame. You should do something like:
for nFrames=1:3
[matches{nFrames}, scores{nFrames}] = vl_ubcmatch(descriptors{nFrames}, descriptors2{nFrames}, 1.5);
end
From here, you should be able to get the matches between the frames.

I need help.
How to pair base on FLIGHTYPE A=Arrival and D=Departure into a single row ?
Just inner join the same table again. In the example below, f1 will contain arrivals and f2 departures.
select f1.*, f2.* -- replace with the list of columns you need
from flights f1
inner join flighs f2
on f1.FLIGHTNO = f2.FLIGHTNO
and f1.FPL_ID <> f2.FPL_ID
and f1.FLIGHTYPE = 'A' and f2.FLIGHTYPE = 'D'
I have a sql database with data about headers of news. Example:

872 Defensoria P blica requer anula o
873 Marcelo Miranda diz que n o possui obriga o
874 Ex-assessor diz que Coimbra lhe deu dois cheques
I need to get each title and see if there are other news to talk about the same subject.
How i do it? My plataform is .Net and use sql server 2012.
You will probably want to put a Full-Text Index on this column and/or table. It's a complex subject, but you can start reading up on it here: http://msdn.microsoft.com/en-us/library/ms142571.aspx
