I am having a beginner question about writing a Sqlite query that I can't seem to figure out:
So you have a table called "D", one column that is called "PersonName", one that is called "DrinkName" and one that is called "CountryName" and you are now looking too see which PersonName has had all DrinkName where CountryName='France' for example.
I have tried by using HAVING COUNT in a numerous different ways but it never works out and I didn't really know where to turn, which is why I am asking you here! Sorry if this question isn't relevant to Stackoverflow or hard to understand, it's my first time here :)
Thanks in advance!

So I have a dictionary of dictionaries. And I want to create a new dictionary containing the exact same data but such that the order of the dictionaries is swapped. (So if I have 'years-->countries-->data about that country in that year' the new dictionary is structured 'countries-->years-->data about that country in that year' and despite studying this for a while (and many many hours of trying) I still can't see to get anywhere. I think part of the problem is I don't know where to start! Any help would be appreciated! Thanks in advance. (Doing this in python btw so help in that language would be especially appreciated!)
I would really like to take the data that would normally be seen by hovering over each column at once. The graph is an interactive one so its hard to extract all the data at once. I would really like it.
I suggest that you pick a programming language that you know fairly well.
Then load the web pages, use a selector to select the desired elements, and output the data in the format you like.
Please begin writing the code, and update your question when you have something working at least partially, so you can ask precisely where you need help
I am creating a table with a lot on columns, and i get the Numeric Overflow error. Is it possible to see for which column i have this error. I do not want to cast everything in there, or comment out chunks until i find it.
Thanks
Andrew's comment is important, so this answer is only related to creating a table, not an insert.
Currently, the only way to know which column is causing the error is to comment out until you find it.
You can help narrow the search by only focusing on numeric related fields.
I want to use the semanticvectors API. I am completely new at this. I want to make a program which takes some documents and searches keywords and returns the documents which are conceptually similar to the search keywords. I want to know if there is any document from which I can get all the function and their functionality description and from which I can learn or if there is any example to do so.
I have checked
https://code.google.com/p/semanticvectors/
and
http://semanticvectors.googlecode.com/svn/javadoc/latest-stable/index.html
but couldn't understand anything. Please help me. Thank you.
It is not clear what you want to do with SemanticVectors. Here is where you should start off with:

And for specific questions, it would be fruitful if you ask on project's forum itself:

What it says on the tin: I have an XMLList, and I want to find where in it a particular XML item falls. First index is good enough for my purposes.
Note that I have no problem writing a function to do this by hand... but I was hoping that the API has something buried somewhere that'll do it for me. I didn't see it, though.
Just loop through the xmllist until you find one that matches, then return the index in your loop (for loop with an index).
Without a code example it's a bit difficult to know what you're trying to do exactly, but maybe XML.childIndex() could the solution?
