I would like to create an application from a database schema using seam-gen, unfortunatly informix isn't supported out of the box.
Where can I add another db?
This line:
used_emails = [row.email for row
in db.execute(select([halo4.c.email], halo4.c.email!=''))]
Returns:
['[email protected]', '[email protected]', '[email protected]', '[email protected]', '[email protected]']
I use this to find a match:
if recipient in used_emails:
If it finds a match I need to pull another field (halo4.c.code) from the database in the same row. Any suggestions on how to do this?
I want to create a Rails (2.1 and 2.2) model with ActiveRecord validations, but without a database table. What is the most widely used approach? I've found some plugins that claim to offer this functionality, but many of them don't appear to be widely used or maintained. What does the community recommend I do? Right now I am leaning toward coming up with my own solution based on this blog post.
I would like to get a list of well-known buildings(museums, castles etc..) within X meters radius of the current coordinate. I would like to query them in PHP.
Do you know any such database that can be queried?
I'm looking for a way to get all rows as insert statements from one specific table within a database using pg_dump in postgres.
eg I have table A and all rows in table a I need as INSERT STATEMENTS, it should also dump those staements to a file
Is this possible?
I am using SQLite to store school classes. I want to fill in a Spinner with the classes that get stored in the database. How would I grab all the classes in the DB and load them into a spinner?
I am integrating LDAP authentication in my web enterprise application. I would like to show listing of people name and email. Instead of querying the LDAP server for the name and email each time a listing containing several users I thought about caching the data locally in the database.
Do you guys know about caching LDAP data best practices?
Should I cache LDAP user data?
When should I insert and refresh the data?

Edit :
Here is some code I already wrote using attachment-fu gem :
http = Net::HTTP.new('awebsite', 443)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
http.start() { |http|
req = Net::HTTP::Get.new("image.jpg")
req.basic_auth login, password
response = http.request(req)
attachment = Attachment.new(:uploaded_data => response.body)
attachement.save
}
And I get an "undefined method `content_type' for #" error

I currently have 5 tables in MySQL database. Some of them share foreign keys and are interdependent of each other. I am displaying classes accordingly to their majors. Each class is taught during the fall, spring or all_year. In my database I have a table named semester which has an id, year, and semester fields. The semester field in particular is a tinyint that has three values 0, 1, 2. This signifies the fall, spring or all_year. When I display the query instead of having it show 0 or 1 or 2 can I have it show fall, spring etc? Extra: How can I add space to the end of each loop so the data doesn't look clustered?
Key
0 Fall
1 Spring
2 All-year

try {
$pdo = new PDO ("mysql:host=$hostname;dbname=$dbname","$username","$pw");

}
$query = $pdo->prepare("SELECT course.name, course.code, course.description, course.hours, semester.semester, semester.year
FROM course
LEFT JOIN major_course_xref ON course.id = major_course_xref.course_id
LEFT JOIN major ON major.id = major_course_xref.major_id

Hey all
i am working at my project where it collects information from two database, one is supplied by the program lets name it DB Y and the other supplied by the user lets name it DB X , now i have an query that depends on companies which is on DB x so i want to transfer this table from DB x to DB y at run time and also checks if there is new updates in DB x and transfer them but i am confused
i have a txt file stored in my sql DB, in that .txt file i have certain numbers like
99435
87889
33455
33555
34556
how to get the count of these numbers from the txtfile stored in the database and also to read the file and fetch the number one bye one in a string.
using asp.net (C#)
Why is that when I search a row in my database, it ended up 0 results? In fact, there are rows that meet my search criterion when I view them manually, but the search button doesnt work as it is. Heres how
you can see there are rows that have '0000-00-00 00:00:00' in them, but when I used the search feature, it ended up like this:
take note that Im entering it in the right field which is 'AcctStopTime'.
TIA
Lets say I'm running a long worker-script in one of several open interactive rails consoles.
The script is updating columns in a very, very, very large table of records. I've muted the ActiveRecord logger to speed up the process, and instruct the script to output some record of progress so I know how roughly how long the process is going to take. That is what I am currently doing and it would look something like this:
ModelName.all.each_with_index do |r, i|
puts i if i % 250
...runs some process...
r.save
end
Sometimes its two nested arrays running, such that there would be multiple iterators and other things running all at once.
Is there a way that I could do something like this and access that variable from a separate rails console? (such that the variable would be overwritten every time the process is run without much slowdown)
records = ModelName.all
$total = records.count
records.each_with_index do |r, i|
$i = i
...runs some process...
r.save
end
meanwhile mid-process in other console
puts "#{($i/$total * 100).round(2)}% complete"
#=> 67.43% complete
I know passing global variables from one separate instance of ruby to the next doesn't work. I also just tried this to no effect as well
unix console 1
$X=5
echo {$X}
#=> 5
unix console 2
echo {$X}
#=> ""
Lastly, I also know using global variables like this is a major software design pattern no-no. I think that's reasonable, but I'd still like to know how to break that rule if I'd like.
Writing to a text file obviously would work. So would writing to a separate database table or something. That's not a bad idea. But the really cool trick would be sharing a variable between two instances without writing to a text file or database column.
What would this be called anyway? Tunneling? I don't quite know how to tag this question. Maybe bad-idea is one of them. But honestly design-patterns isn't what this question is about.
I am developing a WPF client program for some websites. It uses XML database. I am new to XML. Would someone please explain how to create,append(Most important),edit,read&encrypt XML file.

I've made 2 apps, App A and App B. App A's sole purpose is to allow users to sign up and App B's purpose is to take select users from App A email them. Since App A & B were created independently & are hosted in 2 separate Heroku instances, how can App B access the users database in App A? Is there a way to push certain relevant rows from App A to App B?
This is the query to update table in one database that is of other
Update
test.temp a,
test2.temp b
Set a.name=b.name
Where a.no=b.no;
Now I don't want to write every field i.e a.name=b.name
Is there any solution?
