SQL: Seeking an advise for tables structure etc


SQL: Seeking an advise for tables structure etc

Hope that helps First: Don't denormalize your data with "array" columns. That makes it a horror to query, and even worse to update.
Instead, you need two separate tables: small_group_visibility and big_group_visibility. Each of these two tables will consist of msgID and groupID. Basically, it's a many-to-many relationship that's pointing out to both the group and the message it is concerned with.
code :
SELECT DISTINCT msgID, msgSubject, msgBody -- and so on
FROM messages m
LEFT JOIN small_group_visibility sg
  ON sg.msg_id = m.msg_id
LEFT JOIN big_group_visibility bg
  ON bg.msg_id = m.msg_id
WHERE
  sg.group_id IN (1, 2, 3) OR
  bg.group_id IN (10, 20);

it should still fix some issue We put the entire eclipse project folder under version control (with an svn:ignore for the directory containing the compiled classes).
This allows us to share not only the build configuration, but also launch configurations (with the proper VM-parameters), the configuration for compiler warnings the team considers relevant, and the formatter configuration for the coding conventions in use. We can also set text file encodings that way.

I hope this helps you . REST is probably the best architecture for what you're looking for. The more RESTful you get, the better.
OAuth is an authorization protocol, which handles what websites has the authorization to use your credentials. Authorization is different from authentication, although one can use Authorization from another party to ensure authentication.

will be helpful for those in need Under iOS and OS X, Apple provides a great way to do threads without headache: Grand Central Dispatch. Threads aren't expensive, and the system take care of creating the threads for you.
You can use serial queues to process your data and then sync it on the main thread using blocks:
code :
// create the queue that will process your data:
dispatch_queue_t dataProcessQueue = dispatch_queue_create("data process queue", NULL); // the name is there for debugging purposes
    //dispatch to the newly created queue, and do not wait for it to complete
    dispatch_async(dataProcessQueue, ^{
        //your asynchronous job
        dispatch_async(dispatch_get_main_queue(), ^{
            // the work that has to be done on your main thread using data from above
    });
});
// don't forget to release the queue
dispatch_release(dataProcessQueue);

hop of those help? I would advise setting an ENV variable in your Rakefile before each test is run, like this:
code :
ENV['TIMESTAMP_CONTROL'] = Time.now.to_s
assert_equal ENV['TIMESTAMP_CONTROL'], @email_response_text

Hope this helps So off the top of my head you can look at 2 things.
1) Asyncio (be careful this example uses threading and is not thread safe specifically the function asyncio.gather)
code :
import asyncio
for work in [1,2,3,4,5]:
    tasks.append(method_to_be_called(work))

results = await asyncio.gather(*tasks)
