QUESTION
The question says:
Retrieve all unique countries of all publishers.
The column from where I'm supposed to retrieve the countries is the following:
Table: Publisher
Column: Address
Rows:
- Hoboken, New Jersey, United States
- London, United Kingdom
- New York, New York, United States
- New York, New York, United States
- New York, New York, United States
Now, I understand that the answer is asking me is to display: Unites States, United Kingdom. However, the countries are in a string with city, state and country in the case of USA and city and country in the case of UK.
I don't know how to separate the column address into columns, so then I can retrieve the unique values for the countries.
I tried using SUBSTR() and SUBSTRING(), but I have to write the string inside, and I don't know how to write it all into one function.
...ANSWER

QUESTION
I am using a future builder to grab data from a snapshot and filter that data into another Future function that creates markers. I get the results from filtering the locations for all of the restaurants but, the function constantly updates and the data just flickers.

...ANSWER
Answered 2020-Jan-27 at 10:50It's a little hard to tell what's going on without a full code snippet - it'd be much more helpful if you created a small working sample that showed what was going on.
However, I believe there's a few things that might help.
Stop building widgets with functions wherever possible. If it's complex enough to need a function to build it, you should most likely be building it in a widget of its own. This allows flutter to optimize the building of different widgets as well as cleaning up your code.
It's unclear what
_setRestaurants
is, but you're referencing it in the FutureBuilder. The right away of doing this would be for_setRestaurants
to be a Future, and have it only change when a new server request is done. Treat the_setRestaurants
object as part of the state of the widget, and assume that when it changes the widget will be rebuilt. So that would look something like:

I'm working on a dataframe (account
) with two columns containing "posting" IP location (in the column city
) and the locations at the time when those accounts were first registered (in the column register
). I'm using grepl()

I know this may seem easy. I have already entered a code to try and get this to work, but ran into one problem. The format on the link below is the same for all city and states. As long as you can type the name of the city ("City_Search") and the State ("State_Search") you should be able to access the website with the information as seen below.
I have attached the formula I am using below. If anyone can assist me with the search I would appreciate it.
...ANSWER
Answered 2018-Jul-12 at 05:16You need to hyphenate cities that have spaces in their title. Counties need to be the correct abbreviation and both are case sensitive i.e. need to be all lower case. So you need to add these hyphens, if missing, using a function like Replace
in vba, to swop Chr$(32)
with "-" or Chr$(45)
, and potentially LCase$
to convert to lowercase.
You should also fully qualify the range with the worksheet you intend to use.
With data already in correct format in cell:
E.g. with los-angeles-ca
or los-angeles-county-ca
in a cell.

Answered 2018-Apr-09 at 08:12You are having trouble with white space. Normally, sequences of white space are collapsed into a single character, so your displayed HTML document will not have the line breaks from your XML file.
Instead of div
you could use PRE
or you would have to adress the linebreaks within your XSLT to group the content of description
into seperate elements.
QUESTION
I am reading a book about databases and I was wondering if someone could explain something that I can't understand / visualise. I have used relational databases and understand foreign keys etc. My question is, what is a "physical pointer" in a hierarchical data model?
The earlier hierarchical data model is suitable for data structures that are naturally hierarchical, with each data structure placed at a certain level in the hierarchy. However, in the business arena, many of the data structures and their relationships cannot be readily placed in a hierarchical arrangement. The network data model evolved to dispense with the arbitrary restriction of the hierarchical model. Nevertheless, in both of these models, you need physical pointers to connect related data occurrences. This is a serious drawback because you have rewrite the physical addresses in the data records every time you reorganize the data, move the data to a different storage area, or change over to another storage medium. The relational model establishes the connections between related data occurrences by means of logical links implemented through foreign keys.

...ANSWER
Answered 2017-Dec-14 at 07:20A physical pointer is any value that indicates where something is located, e.g. a memory address, position in an array or collection, a file system path, OID, etc.
In contrast, the relational model identifies things by their own attributes - natural keys or assigned surrogate keys. This adds a layer of abstraction and complexity to the DBMS, but isolates users from the organization of system data structures.
For example, in hierarchical data structures, each child record might contain the address of its parent record, while a parent record might hold an array of its children's addresses.
