I am using C# 4.0, how can I avoid the problem of writing lots of similiar methods because they are each parameter-unique (how can the new parameter features avoid overload hell?).
Thanks
Hi.
Scala implicits are very powerfull. I'm curious if they are a new/unique feature of Scala, or the concept already existed in other programming languages.
Thanks.
Note: I have used the tag "implicit" instead of "implicits" because it doesn't exists and I can't create new tags...
The goal of this query is to get a total of unique records (by IP) per ref ID.
SELECT COUNT(DISTINCT ip), GROUP_CONCAT(ref.id)
FROM `sess` sess
JOIN `ref` USING(row_id)
WHERE sess.time BETWEEN '2010-04-21 00:00:00' AND '2010-04-21 23:59:59'
GROUP BY ref.id
ORDER BY sess.time DESC
The query works fine, but its using a temporary table. Any ideas?
I'm surprised by the number of general education classes computer science students must complete to get their bachelors. For example, I must take:
three English classes
two history classes
public speaking
economics
biology
I hardly think these general education requirements are unique to the university I attend. My question is (for those of you who have degrees), in what ways have these general education requirements improved your career as a programmer?
I have a model:
class Example(models.Model):
unique_hash = models.CharField(max_length=32,unique=True)
content = models.FileField(upload_to='source',blank=True,verbose_name="HTML Content File")
I would like to be able to set the content filename to default to a callable, but I don't see any way to have the callable reference unique_hash (or vice versa). Is this possible?
Here's the situation. I have a bunch of objects that implement Serializable that I want to store in a SQL database. I have two questions
Is there a way to serialize the object directly into the database
Is that the best way to do it or should I
Write the object out to a formatting String and put it in the database that way and then parse it back out
Write each member to the database with a field that is unique to each object
Hi,
If I have a column, set as primary index, and set as INT.
If I don't set it as auto increment and just insert random integers which are unique into it, does that slow down future queries compared to autincrementing?
Does it speed things up if I run OPTIMIZE on a table with its primary and only index as INT? (assuming only 2 columns, and second column is just some INT value)
(the main worry is the upper limit on the autoincrement as theres lots of adds and deletes in my table)
Hi,
I have a very unique requirement for a rich text box with spell check and auto text. The spell check will not happen on any other site thus i need to have the dictionary and the spell check logic in my site only. It should be open source as i will then add auto text feature to that text box. Any help will be appreciated.
Thanks.
The official documentation says they are optional. I know COM interop requires a unique identifier for each interface but every interface example I see has a GUID whether it's used with COM or not? Is there any benefit to including a GUID if its not going to be used with COM?
I'm looking for a way of mapping a uid (unique number representing a system user) to a user name using Perl.
Please don't suggest greping /etc/passwd :)
Edit
As a clarification, I wasn't looking for a solution that involved reading /etc/passwd explicitly. I realize that under the hood any solution would end up doing this, but I was searching for a library function to do it for me.
Each input field in the CKEditor dialogs are renamed with a unique number, but the number changes depending on what options are visible.
I need to reference 'txtUrl' which has an id something like #35_textInput.
So far I have discovered that something like this should work:
alert(CKEDITOR.instances.myElement.document.$.body.getId('txtUrl'));
But it doesn't. Please help.
Does the original data type of the username string in a call to FormsAuthentication.SetAuthCookie(...) make any difference with regards to security or code maintainability?
As I understand it, the cookie is encrypted and used to identify a user on each request. I'm curious whether it should affect the design of the primary key on my Users table in my database, eg. Guid vs int or a unique username string.
Hi, I believe this is a tough one...
I'm trying to create a collection of variable binding in a class.
It is intended to look something like this:
Dim x as integer, s as string
Dim c as new VBindClass
x = 1
s = "Hello"
c.Add x, s
Debug.Print c.value(x) '= 1
Debug.Print c.value(s) '= "Hello"
Is there some function that allow us to retrieve a unique ID for a given variable and also get/set based on variable?
I am using a D2k 6i form and getting the error on form throught stored database(oracle9i) procedure ORA-00001 Unique constraint but i m not able to trace out from where it is coming
can anybody help me regarding this
I have more than 1000 access databases with the same table names.Each database has a unique name. In each database, I want to add column to one existing table and populate that new column (all rows in the table would be the same) with the database name. I found the example below - How can I alter this to give the new column the name of the database.
ALTER TABLE TestTable ADD NewColumn INT;
UPDATE TestTable SET NewColumn = 0;
I am trying to parse a list of operating system instances with their unique identifiers. I am looking for a solution to parse a text string, and pass the values into two variables. The string to be parsed is as followed:
"Ubuntu 9.10" {40f2324d-a6b2-44e4-90c3-0c5fa82c987d}
What is the easiest and most efficient way to create an auto-increment counter for every data row in google appengine?
basically I want to give every row a unique row_number so that I can overcome the issue of only being able to get the first 1000 results in a select query. I can thus add a counter lies between condition and mine all the entires in the table.
How can I use randomize and rnd to get a repeating list of random variables?
By repeating list, I mean if you run a loop to get 10 random numbers, each random number in the list will be unique. In addition, if you were to run this sequence again, you would get the same 10 random numbers as before.
Hey all,
I have a table Logins { Id, AccessTime }, I'd like to write a query that returns 3 columns, Total Logins during a time period, Unique Logins for a time period, and the Id of the user.
I know I could do this with two passes and a join, is there a better way to do it in a single pass?
Thanks,
~P
Suppose I have my models set up already.
class books(models.Model):
title = models.CharField...
ISBN = models.Integer...
What if I want to add this column to my table?
user = models.ForeignKey(User, unique=True)
How would I write the raw SQL in my database so that this column works?
Hello all,
How do I get the id of an input element based on its value? The values will always be unique and there are only 7 of them. I have tried this:
$('#wrapper').find("input[value='"+value+"']").each(function(){
return this.id;
});
But nothing is returned!
Thanks all for any help
Hi,
I'm using Views in Drupal.
I want an exposed filter selecting the ndoes containing a specific word. But I noticed I cannot search more then one CCK field per filter.
Since I want to expose it, I want an unique text-input field for all CCK Fields: is that possible ?
At the moment I can only add a new filter for each CCK field.
Thanks
Will the following piece of code work as expected in a multi-threaded scenario?
int getUniqueID()
{
static int ID=0;
return ++ID;
}
It's not necessary that the IDs to be contiguous - even if it skips a value, it's fine.
Can it be said that when this function returns, the value returned will be unique across all threads?
Does Doctrine 1.2 support importing indexes with Doctrine_Core::generateModelsFromDb() function?
I need to make a migration between 2 database connections, one of them having unique index on 2 fields and one doesn't. And my migration is empty. It looks like Doctrine doesn't support indexes when importing from databae, other than those tied to relationship foreign keys.
$changes = Doctrine_Core::generateMigrationsFromDiff($migrationsPath,
array('doctrineOld'),
array('doctrine'));
